Battery, NoSubGridsThe keyword NoSubGrids will restrict the search to those blocks which are on the same grid as the programmable block running FSD v2 (PB).

Battery, OnlySubGridsThe keyword OnlySubGrids will restrict the search to those blocks which are noton the same grid as the programmable block running FSD v2 (PB).

Battery , AddInfoThat will help telling the two output modes (alternative data sources) apart, by putting one of the following small texts between the central symbol and the percentage value.

FSD can clone the text content of other displays. These texts can be fixed or could be generated by other scripts (like Automatic LCDs 2 by MMaster or Isy"s Inventory Manager)

LCD Panel, clone:0 position(100,50) fontsize=0.5 TextColor(255,128,0)This would clone the text contend of the first screen of the block "LCD Panel" to the position (x=100 y=50) in an orange color with a font size of 0.5.

This way you can ether reduce the number of LCD Panels needed or greatly enhance the amount of information you can display with a given set of screens/panels.

Caution: There has to be no space between "layoutrate" and the equals sign "="This will set the rate of changes for the screen layouts. (in changes per minute)

You can overide individual LCD/Cockpit screen settings by using a special keyword line starting with "FSD options:" in the Custom Data field of the Programmable block itself.

All keywords for this override options must be in a single line and this line must be located above an optional "ShowStats" line or else the used keywords affect only the LCD panels of the Programmable block.

Visual Script Builder allows you to create Space Engineers scripts with a user interface. You don"t need to know anything about programming. Just enter the name of the block you want to control and choose what to do with it. Chain logic statements together to create complex behaviors.

A large number of Space Engineers players are unable to utilize programming. The scripting documentation is poor, and the in-game editor doesn"t provide any help. Many people are unfamiliar with coding, and C# in Space Engineers doesn"t make for a simple beginner language. There are scripts available on the Steam Workshop, but those rarely work for custom applications.

I developed this tool to let anyone capable of playing Space Engineers write their own custom scripts. I tried to make it as feature-rich as possible while still being easy to use.

In Visual Script Builder, everything is driven by logic chunks. One logic chunk can either check a condition (e.g. If Light X is ON), or apply an action (e.g. Turn Light Y ON). You can insert logic chunks and remove logic chunks at any point in the script. There is no limit to the number of logic chunks you can use. Each logic chunk consists of the logic type, the in-game Space Engineers block it applies to, and the in-game block"s data.

For example, if you want to get only Batteries that have a name including "Station", you can enter "Station" in the block name field, and choose All Blocks of Type. This will select only the Batteries that have "Station" somewhere in their name. It will get Batteries named "Station Battery 5" and "Battery 3 [Station]" but would not get a battery named "Battery 2", because it does not include the filter text.

You can add to numeric variables using a plus sign (+), or subtract from them using a minus sign (-). If you wanted the total stored power in all of your batteries, you could add each Stored Power value together by choosing All Blocks of TypeBattery, then saving the Stored Power as +totalpower to create a variable totalpower, which would have the sum of all Stored Power values from your Batteries.

When writing the text you want displayed on an LCD panel, you can use any variables that you created in your script by surrounding them with brackets. For example, if you saved a variable called totalpower, you could display its value on an LCD panel by writing [totalpower]. This can be combined with any other text, or any other variables. Total Power: [totalpower] would display Total Power: 3.00MW. See additional information about using LCD panels below.

Don"t worry about highlighting and copying, just click the button to copy your entire script to the clipboard and paste it into the editor in Space Engineers.

As you can see, our variable (here named variableName) is followed by a question mark (?), the text to display when true (trueText), a colon (:), and the text to display when false (falseText). For use on the LCD panel, we must enclose this whole string in brackets. In a more realistic scenario, we might want to display ON when our Reactor is on, and OFF when our Reactor is off. We can create a boolean variable called reactorOn for the Reactor"s On/Off state by typing a new variable name (reactorOn) into the Save As box for the OnOff property of the Reactor. For this property, true means the reactor is on. To get the text to display correctly, we can type the following into an LCD panel.

As of Update 1.0.3, it"s also possible to do calculations right inside the text of the LCD panel. This allows you to display your power percentage. Mathematically, power percentage is:

The Block Name box is where you enter the name of the Space Engineers block you want to work with. If this is left blank, the default value will be used for the chosen block type. Leave this blank.

That"s it! You"re now ready to try the script out. Click the Copy Script To Clipboard button, and paste the code into a Programmable Block in Space Engineers. Running the code will toggle on/off an Interior Light with the name "Interior Light".

In Space Engineers, create a Programmable Block. Go into the Programmable Block"s menu and click Edit. Delete everything in the editor and paste in your script. CTRL-C and CTRL-V work in the editor. Click Check Code to check the code for errors, then click Remember & Exit to save. Be careful, as using ALT-TAB to switch out of Space Engineers will revert your script to the last saved script. It is easy to lose your changes.

To run the script, open the Programmable Block"s menu and click Run. You can also assign this action to your toolbar in a ship, or to a button panel by dragging the Programmable Block to the bar and choosing Run with default argument.

If you want your script to be run constantly (for example, waiting for a door to open and triggering the lights to turn on) you can use the Frequency dropdown in the Script Settings menu. It will automatically run your script every 1, 10, or 100 ticks. There are 60 ticks per second in-game. This feature was introduced in version 1.0.8, but can cause issues when trying to use Arguments in the Programmable Block. With older versions, or to avoid issues with Arguments, you have to use a timer block. Create a Timer block and set the Trigger Delay to 1 second. Click Setup Actions, and drag your Programmable Block to the first space on the bar. Again, use Run with default argument. Then drag your Timer block to the next space on the bar and choose Start. Now start the Timer block, and your script will be executed every second.

Samsung is unquestionably the leader in the mobile display space. Its OLED panels are second to none, and the Korean giant is far from complacent in its leading position. Quite the contrary. Samsung Display is constantly innovating, and the Galaxy S22 gets to reap the benefits of the latest and greatest up on offer. This is actually one aspect in which the trio of Galaxy S22 devices differs rather significantly. Unfortunately, Samsung has been struggling a bit to properly communicate the subtle display performance nuances within the Galaxy S22 line and has been forced to clarify certain points multiple times already.

Let"s start with brightness. There are major brightness improvements across the board on the Galaxy S22 phones. However, the S22+ and S22 Ultra are expected to reach higher max brightness values than the vanilla S22. Specifically, Samsung claims both phones should be capable of a whopping 1,750 nits of peak brightness. This is obviously not achievable while the entire display is shining white. That"s just how OLED panels work in general.

It is a bit hard to say exactly what made this feat of engineering possible. Official resources are a bit scarce too. Best we can gather, Samsung is using a new generation of LED emitters, which some sources refer to as the M12 OLED panel (as opposed to the M11 found in the Galaxy S21 Ultra and allegedly, the iPhone 13 Pro and Pro Max). This new generation of OLED pixels manages higher brightness and better efficiency. About 16% better if this one slide we found is to be believed.

On the subject of colors, we expect nothing short of excellence from Samsung"s flagships and, for the most part, were not disappointed by the Galaxy S22+. The S22+ has just two color modes in typical Samsung fashion - Vivid and Natural. The first aims for the DCI-P3 color space and gets pretty close to what we would consider color-accurate. The color volume is there, but the default palette is just a bit too cold. Using the manual slider to warm up the colors by one move on the slider results in deviation within what we would consider DCI-P3 color accurate.

Netflix was more than happy to serve us the maximum 1080p resolution needed to saturate the native 1080p+ resolution of the S22+ in gorgeous HDR, which, as you can imagine, really pops thanks to the incredible maximum brightness of its panel.

From what we managed to gather, only the S22 Ultra actually uses an LTPO 2.0 substrate for its OLED panel, allowing it much better flexibility in automatic refresh rate adjustment. The S22+ and vanilla S22 rely on the simpler LTPS tech, which Samsung still managed to expand for this generation

In order to properly explain our findings, we need to make a distinction between screen refresh rate and UI rendering or framerate. Checking the Android 12 support APIs on the S22+ reveals that its panel can refresh in one of the following modes: 10Hz, 24Hz, 30Hz, 48Hz, 60hz, 96Hz and 120Hz. The actual fps the UI is being rendered at is not the same figure as the ones quoted above. In order to monitor that, Samsung has included a nifty tool in the Developer menu called GPU Watch, which exposes an overlay for what the Android SurfaceFlinger is outputting to the graphical buffer. In other words, this is an fps counter rather than a refresh rate setting for the display.

The lowest refresh rate the S22+ reaches while idling on a static image is actually 24Hz. Despite the phone"s display reporting in software that it can switch down to 10Hz, we never actually managed to get that figure in any scenario during our testing. What we did manage to see, however, were fps readings from the Android SurfaceFlinger as low as 1fps, though not officially advertised. Oddly, this falls in line reasonably well with Samsung"s revised statements regarding the behavior of the S22+ and how it achieves battery savings. What is happening in practice is a refresh rate drop to as low as 24Hz accompanied by an fps drop to as low as 1fps in order to save power.

One exception to the norm we noticed was related to HDR video playback in particular. Once HDR gets actually triggered and the display enters "HDR mode," its refresh rate gets locked to 120Hz regardless of the fps of the HDR content being played. This is not ideal for battery savings, but it seems to be a limitation of the hardware rather than software, since the S22 Ultra maintains its refresh rate switching logic during HDR playback, likely thanks to its LTPO 2.0 tech. This, however, is a case of the S22 Ultra excelling at what it does, rather than a deficiency to attribute to the S22+.

In one of Samsung"s more controversial decisions this generation, the Galaxy S22+ and S22 have both lost battery capacity over last year - 300mAh each, to be exact. That has left the S22+ with 4,500 mAh instead of the 4,800 mAh in the S21+. Samsung"s hope was likely to make the difference up through its more efficient 4nm chipsets, as well as software and specifically adaptive refresh rate tricks.

Unfortunately, the S22+ does not excel in the battery department, scoring 97 hours in our standardized test. To be clear, that"s a solid, even if unimpressive, showing from the S22+, which in practice managed to get us through about a day and a half on a single charge.

In any case, the S22+ does still manage better overall endurance than the Galaxy S21 FE on the same battery capacity even if it does fall notably behind the Galaxy S21+ with its 114 hours on a 4,800 mAh battery.

Our battery tests were automated thanks to SmartViser, using its viSerDevice app. The endurance rating denotes how long the battery charge will last you if you use the device for an hour of telephony, web browsing, and video playback daily. More details can be found here.

Video test carried out in 60Hz refresh rate mode. Web browsing test done at the display"s highest refresh rate whenever possible. Refer to the respective reviews for specifics. To adjust the endurance rating formula to match your own usage patterns check out our all-time battery test results chart where you can also find all phones we"ve tested.

After testing the S22+, as well as the Ultra with genuine Samsung 25W and 45W chargers available at the time of writing this, we can confirm that nothing has really changed, and in practice, these chargers still top-off the battery at effectively the same rate. That is to say, a full charge takes right around an hour.

While on the topic, we definitely appreciate the addition of the new option (even if well-hidden) to limit battery charging to 85% on top of the already available toggles for turning off Fast Charging. Still, there is room for improvement in this department. We would love to see some sort of smart charging system be implemented, akin to Qnovo or Apple"s relatively new Optimized Battery Charging option as ways to safely overnight charge. But, we digress.

If you do insist on going down the third-party road and can at least test the charger, there are some clues to tell if it is charging the S22+ at the maximum speed. When you connect it on a 1% battery, the estimate for a full charge should be around an hour. Also, the charging text changes according to the kind of charging speed the S22+ has negotiated with the charger. While there is no official info on this, according to our testing, a charging rate of 12W or less will simply say Charging. The text Fast Charging appears with a charging of around 15W to 18W. These figures could potentially be higher, but some of Samsung"s own "Super Fast Charging" conditions aren"t met.

Various cells and batteries (top left to bottom right): two AA, one D, one handheld ham radio battery, two 9-volt (PP3), two AAA, one C, one camcorder battery, one cordless phone battery

A battery is a source of electric power consisting of one or more electrochemical cells with external connectionselectrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode.redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.

Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead-acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.

Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers. Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting electrical energy to mechanical work, compared to combustion engines.

In the 1930s, the director of the Bagdad Museum and Iraq Antiquities Department Wilhelm König reported the discovery of the Baghdad battery, a first century device consisting of a ceramic pot, copper, and iron. His assumption was that it was used for electroplating, but later theories suggest it may have been a medical device used for electrotherapy.

Batteries in vacuum tube devices historically used a wet cell for the "A" battery (to provide power to the filament) and a dry cell for the "B" battery (to provide the plate voltage).

Between 2010 and 2018, annual battery demand grew by 30%, reaching a total of 180 Gwh in 2018. Conservatively, the growth rate is expected to be maintained at an estimated 25%, culminating in demand reaching 2600 Gwh in 2030. In addition, cost reductions are expected to further increase the demand to as much as 3562 GwH.

Distributed electric batteries, such as those used in battery electric vehicles (vehicle-to-grid), and in home energy storage, with smart metering and that are connected to smart grids for demand response, are active participants in smart power supply grids.vehicle electric batteries that have their battery capacity reduced to less than 80%, usually after service of 5–8 years, are repurposed for use as backup supply or for renewable energy storage systems.

A battery consists of some number of voltaic cells. Each cell consists of two half-cells connected in series by a conductive electrolyte containing metal cations. One half-cell includes electrolyte and the negative electrode, the electrode to which anions (negatively charged ions) migrate; the other half-cell includes electrolyte and the positive electrode, to which cations (positively charged ions) migrate. Cations are reduced (electrons are added) at the cathode, while metal atoms are oxidized (electrons are removed) at the anode.

Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless.

Primary batteries, or primary cells, can produce current immediately on assembly. These are most commonly used in portable devices that have low current drain, are used only intermittently, or are used well away from an alternative power source, such as in alarm and communication circuits where other electric power is only intermittently available. Disposable primary cells cannot be reliably recharged, since the chemical reactions are not easily reversible and active materials may not return to their original forms. Battery manufacturers recommend against attempting to recharge primary densities than rechargeable batteries,loads under 75 ohms (75 Ω). Common types of disposable batteries include zinc–carbon batteries and alkaline batteries.

Secondary batteries, also known as secondary cells, or lead–acid battery, which are widely used in automotive and boating applications. This technology contains liquid electrolyte in an unsealed container, requiring that the battery be kept upright and the area be well ventilated to ensure safe dispersal of the hydrogen gas it produces during overcharging. The lead–acid battery is relatively heavy for the amount of electrical energy it can supply. Its low manufacturing cost and its high surge current levels make it common where its capacity (over approximately 10 Ah) is more important than weight and handling issues. A common application is the modern car battery, which can, in general, deliver a peak current of 450 amperes.

A wet cell battery has a liquid electrolyte. Other names are flooded cell, since the liquid covers all internal parts or vented cell, since gases produced during operation can escape to the air. Wet cells were a precursor to dry cells and are commonly used as a learning tool for electrochemistry. They can be built with common laboratory supplies, such as beakers, for demonstrations of how electrochemical cells work. A particular type of wet cell known as a concentration cell is important in understanding corrosion. Wet cells may be primary cells (non-rechargeable) or secondary cells (rechargeable). Originally, all practical primary batteries such as the Daniell cell were built as open-top glass jar wet cells. Other primary wet cells are the Leclanche cell, Grove cell, Bunsen cell, Chromic acid cell, Clark cell, and Weston cell. The Leclanche cell chemistry was adapted to the first dry cells. Wet cells are still used in automobile batteries and in industry for standby power for switchgear, telecommunication or large uninterruptible power supplies, but in many places batteries with gel cells have been used instead. These applications commonly use lead–acid or nickel–cadmium cells. Molten salt batteries are primary or secondary batteries that use a molten salt as electrolyte. They operate at high temperatures and must be well insulated to retain heat.

A gel battery. A common dry cell is the zinc–carbon battery, sometimes called the dry Leclanché cell, with a nominal voltage of 1.5 volts, the same as the alkaline battery (since both use the same zinc–manganese dioxide combination). A standard dry cell comprises a zinc anode, usually in the form of a cylindrical pot, with a carbon cathode in the form of a central rod. The electrolyte is ammonium chloride in the form of a paste next to the zinc anode. The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolariser. In some designs, the ammonium chloride is replaced by zinc chloride.

A reserve battery can be stored unassembled (unactivated and supplying no power) for a long period (perhaps years). When the battery is needed, then it is assembled (e.g., by adding electrolyte); once assembled, the battery is charged and ready to work. For example, a battery for an electronic artillery fuze might be activated by the impact of firing a gun. The acceleration breaks a capsule of electrolyte that activates the battery and powers the fuze"s circuits. Reserve batteries are usually designed for a short service life (seconds or minutes) after long storage (years). A water-activated battery for oceanographic instruments or military applications becomes activated on immersion in water.

On 28 February 2017, the University of Texas at Austin issued a press release about a new type of solid-state battery, developed by a team led by lithium-ion battery inventor John Goodenough, "that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage".

Sony has developed a biological battery that generates electricity from sugar in a way that is similar to the processes observed in living organisms. The battery generates electricity through the use of enzymes that break down carbohydrates.

The sealed valve regulated lead–acid battery (VRLA battery) is popular in the automotive industry as a replacement for the lead–acid wet cell. The VRLA battery uses an immobilized sulfuric acid electrolyte, reducing the chance of leakage and extending shelf life.

In the 2000s, developments include batteries with embedded electronics such as USBCELL, which allows charging an AA battery through a USB connector, nanoball batteries that allow for a discharge rate about 100x greater than current batteries, and smart battery packs with state-of-charge monitors and battery protection circuits that prevent damage on over-discharge. Low self-discharge (LSD) allows secondary cells to be charged prior to shipping.

Standard-format batteries are inserted into battery holder in the device that uses them. When a device does not uses standard-format batteries, they are typically combined into a custom battery pack which holds multiple batteries in addition to features such as a battery management system and battery isolator which ensure that the batteries within are charged and discharged evenly.

It covered 2,000 square metres (22,000 sq ft)—bigger than a football pitch—and weighed 1,300 tonnes. It was manufactured by ABB to provide backup power in the event of a blackout. The battery can provide 40 MW of power for up to seven minutes.Sodium–sulfur batteries have been used to store wind power.

Many important cell properties, such as voltage, energy density, flammability, available cell constructions, operating temperature range and shelf life, are dictated by battery chemistry.

Smaller volume than equivalent Li-ion. Extremely expensive due to silver. Very high energy density. Very high drain capable. For many years considered obsolete due to high silver prices. Cell suffers from oxidation if unused. Reactions are not fully understood. Terminal voltage very stable but suddenly drops to 1.5 volts at 70–80% charge (believed to be due to presence of both argentous and argentic oxide in positive plate; one is consumed first). Has been used in lieu of primary battery (moon buggy). Is being developed once again as a replacement for Li-ion.

Very expensive. Very high energy density. Not usually available in "common" battery sizes. Lithium polymer battery is common in laptop computers, digital cameras, camcorders, and cellphones. Very low rate of self-discharge. Terminal voltage varies from 4.2 to 3.0 volts during discharge. Volatile: Chance of explosion if short-circuited, allowed to overheat, or not manufactured with rigorous quality standards.

A battery"s characteristics may vary over load cycle, over charge cycle, and over lifetime due to many factors including internal chemistry, current drain, and temperature. At low temperatures, a battery cannot deliver as much power. As such, in cold climates, some car owners install battery warmers, which are small electric heating pads that keep the car battery warm.

A battery"s capacity is the amount of electric charge it can deliver at the rated voltage. The more electrode material contained in the cell the greater its capacity. A small cell has less capacity than a larger cell with the same chemistry, although they develop the same open-circuit voltage.amp-hour (A·h). The rated capacity of a battery is usually expressed as the product of 20 hours multiplied by the current that a new battery can consistently supply for 20 hours at 68 °F (20 °C), while remaining above a specified terminal voltage per cell. For example, a battery rated at 100 A·h can deliver 5 A over a 20-hour period at room temperature. The fraction of the stored charge that a battery can deliver depends on multiple factors, including battery chemistry, the rate at which the charge is delivered (current), the required terminal voltage, the storage period, ambient temperature and other factors.

Batteries that are stored for a long period or that are discharged at a small fraction of the capacity lose capacity due to the presence of generally irreversible side reactions that consume charge carriers without producing current. This phenomenon is known as internal self-discharge. Further, when batteries are recharged, additional side reactions can occur, reducing capacity for subsequent discharges. After enough recharges, in essence all capacity is lost and the battery stops producing power. Internal energy losses and limitations on the rate that ions pass through the electrolyte cause battery efficiency to vary. Above a minimum threshold, discharging at a low rate delivers more of the battery"s capacity than at a higher rate. Installing batteries with varying A·h ratings does not affect device operation (although it may affect the operation interval) rated for a specific voltage unless load limits are exceeded. High-drain loads such as digital cameras can reduce total capacity, as happens with alkaline batteries. For example, a battery rated at 2 A·h for a 10- or 20-hour discharge would not sustain a current of 1 A for a full two hours as its stated capacity implies.

The C-rate is a measure of the rate at which a battery is being charged or discharged. It is defined as the current through the battery divided by the theoretical current draw under which the battery would deliver its nominal rated capacity in one hour.h−1. Because of internal resistance loss and the chemical processes inside the cells, a battery rarely delivers nameplate rated capacity in only one hour. Typically, maximum capacity is found at a low C-rate, and charging or discharging at a higher C-rate reduces the usable life and capacity of a battery. Manufacturers often publish datasheets with graphs showing capacity versus C-rate curves. C-rate is also used as a rating on batteries to indicate the maximum current that a battery can safely deliver in a circuit. Standards for rechargeable batteries generally rate the capacity and charge cycles over a 4-hour (0.25C), 8 hour (0.125C) or longer discharge time. Types intended for special purposes, such as in a computer uninterruptible power supply, may be rated by manufacturers for discharge periods much less than one hour (1C) but may suffer from limited cycle life.

Battery life (and its synonym battery lifetime) has two meanings for rechargeable batteries but only one for non-chargeables. For rechargeables, it can mean either the length of time a device can run on a fully charged battery or the number of charge/discharge cycles possible before the cells fail to operate satisfactorily. For a non-rechargeable these two lives are equal since the cells last for only one cycle by definition. (The term shelf life is used to describe how long a battery will retain its performance between manufacture and use.) Available capacity of all batteries drops with decreasing temperature. In contrast to most of today"s batteries, the Zamboni pile, invented in 1812, offers a very long service life without refurbishment or recharge, although it supplies current only in the nanoamp range. The Oxford Electric Bell has been ringing almost continuously since 1840 on its original pair of batteries, thought to be Zamboni piles.

The active material on the battery plates changes chemical composition on each charge and discharge cycle; active material may be lost due to physical changes of volume, further limiting the number of times the battery can be recharged. Most nickel-based batteries are partially discharged when purchased, and must be charged before first use.

Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, which slows the side reactions. Such storage can extend the life of alkaline batteries by about 5%; rechargeable batteries can hold their charge much longer, depending upon type.Duracell do not recommend refrigerating batteries.

A battery explosion is generally caused by misuse or malfunction, such as attempting to recharge a primary (non-rechargeable) battery, or a short circuit.

When a battery is recharged at an excessive rate, an explosive gas mixture of hydrogen and oxygen may be produced faster than it can escape from within the battery (e.g. through a built-in vent), leading to pressure build-up and eventual bursting of the battery case. In extreme cases, battery chemicals may spray violently from the casing and cause injury. An expert summary of the problem indicates that this type uses "liquid electrolytes to transport lithium ions between the anode and the cathode. If a battery cell is charged too quickly, it can cause a short circuit, leading to explosions and fires".hydrogen, which is very explosive, when they are overcharged (because of electrolysis of the water in the electrolyte). During normal use, the amount of overcharging is usually very small and generates little hydrogen, which dissipates quickly. However, when "jump starting" a car, the high current can cause the rapid release of large volumes of hydrogen, which can be ignited explosively by a nearby spark, e.g. when disconnecting a jumper cable.

Overcharging (attempting to charge a battery beyond its electrical capacity) can also lead to a battery explosion, in addition to leakage or irreversible damage. It may also cause damage to the charger or device in which the overcharged battery is later used.

Many battery chemicals are corrosive, poisonous or both. If leakage occurs, either spontaneously or through accident, the chemicals released may be dangerous. For example, disposable batteries often use a zinc "can" both as a reactant and as the container to hold the other reagents. If this kind of battery is over-discharged, the reagents can emerge through the cardboard and plastic that form the remainder of the container. The active chemical leakage can then damage or disable the equipment that the batteries power. For this reason, many electronic device manufacturers recommend removing the batteries from devices that will not be used for extended periods of time.

Many types of batteries employ toxic materials such as lead, mercury, and cadmium as an electrode or electrolyte. When each battery reaches end of life it must be disposed of to prevent environmental damage.electronic waste (e-waste). E-waste recycling services recover toxic substances, which can then be used for new batteries.

Batteries may be harmful or fatal if swallowed.button cells can be swallowed, in particular by young children. While in the digestive tract, the battery"s electrical discharge may lead to tissue damage;gastrointestinal tract. The most common place for disk batteries to become lodged is the esophagus, resulting in clinical sequelae. Batteries that successfully traverse the esophagus are unlikely to lodge elsewhere. The likelihood that a disk battery will lodge in the esophagus is a function of the patient"s age and battery size. Older children do not have problems with batteries smaller than 21–23 mm. Liquefaction necrosis may occur because sodium hydroxide is generated by the current produced by the battery (usually at the anode). Perforation has occurred as rapidly as 6 hours after ingestion.

In the United States, the Mercury-Containing and Rechargeable Battery Management Act of 1996 banned the sale of mercury-containing batteries, enacted uniform labeling requirements for rechargeable batteries and required that rechargeable batteries be easily removable.

The Battery Directive of the European Union has similar requirements, in addition to requiring increased recycling of batteries and promoting research on improved battery recycling methods.
