It is bad to touch an exploded battery as the chemicals can get onto the skin and cause rashes or chemical burns or other irritation.
You should only touch the exploded battery wearing gloves or by using a shovel tongs etc.
You can know if a battery explodes by hearing a loud explosion or popping sound depending on the size of the battery.
Larger batteries that explode may sound like a loud gunshot and smaller batteries may sound like a firecracker.
Other signs that a battery is about to explode are the battery swells up, the battery gets hot, the device gets hot, you smell a bad chemical smell, the battery is smoking or liquids are leaking from the battery.
If a battery is about to explode you should use a pair of tongues or something else to safely hold the battery and take it outside and place it in a fireproof container such as a metal can that is sealed or metal bucket of sand or put into some sand or on a concrete surface.
Batteries explode or leak due to hydrogen building up in the battery which causes pressure buildup in the battery's insulating seals to come open and leak.
Lithium and lithium ion batteries can burn underwater which is why spraying and blasting lithium fires with water does not put the fire out right away.
Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen.
The colorless solution is highly alkalic.
The likelihood of a lithium battery fire is very low and it's very unlikely that you would have a lithium battery fire as long as you follow proper discarding, charging and storage procedures for the lithium ion batteries.
Lithium ion batteries do start fires but it's not as common as most people think.
Lithium batteries swell because of chemical reactions that produce power no longer completing fully which results in the creation of gasses which cause the battery to explode.
Lithium and other batteries also swell due to electrolyte decomposition.
Too much current flowing through the batteries can also cause the battery to swell due to a buildup in gasses and heat.
A battery explosion is almost as loud as a gunshot.
The plastic case blows apart and then the sound of toxic and highly concentrated sulfuric acid bubbles to the ground.
And automotive battery explosions can cause severe injury and can even be fatal, depending on where one is standing during the explosion.
The chemical that makes batteries explode is hydrogen gas which is explosive in certain concentrations in the air.
The flammability or explosive limits for hydrogen gas is 4.1% to 72% hydrogen in air.
The most explosive battery is the Lithium based batteries which are very powerful and can be highly explosive and when recharged repeatedly dendrites can form and trigger a short circuit which causes the battery to burst into flames and explode.
The white powder from battery is potassium carbonate which is electrolyte potassium hydroxide that is reacted with O2 in order to form Potassium Carbonate.
When in this condition with the white powder from the battery the battery is no longer usable and Potassium carbonate is a very strong alkaline and water soluble material.
If you pierce a AAA battery or AA battery or any other battery then the acidic material or alkaline can leak out of the body and lead to corrosive injury to the body if touched.
AA, AAA and other batteries can sizzle when hydrogen gas is building up inside the battery and the battery is trying to open to vent the hydrogen gas.
The battery may also be leaking and may be going bad as well.
All AA batteries are the same although some AA batteries are made to last a bit longer than other AA batteries and some AA batteries are also designed to work in more extreme temperatures and have a longer storage life than other AA batteries.
The AA battery that lasts the longest is the Energizer Ultimate Lithium AA battery.
The Energizer Ultimate Lithium AA battery has a 20 year storage life and can work in temperatures of 104 F to 140 F.
Amazon batteries are worth it and they work just as good as name brand batteries and are cheaper.
I buy Amazon batteries and find them just as good as other batteries and they are cheaper as well.
Amazon has the best AA battery price when you buy the AA batteries in bulk.
It's cheaper to buy the AA batteries in bulk than it is to buy them in smaller amounts such as a single package from a store.
Generic AA batteries are just as good as name brand for most devices.
However if you need a longer lasting battery in high drain devices then buying the name brand batteries can be a better choice.
But for lower drain devices such as remote controls, clocks etc, led flashlights etc then the generic AA batteries are just as good as the name brand and will work fine.
Some AA batteries do last longer than others.
Some of the name brand AA batteries last longer than some of the generic cheaper brands.
For example Duracell and Energizer AA batteries tend to last a bit longer than cheaper batteries do.
Cheap AA batteries last for 18 hours to 24 hours when used and when unused the cheap AA batteries last from 3 to 5 years.
Higher drain devices will drain the batteries faster than lower drain devices.
The brand of batteries that last the longest are Energizer batteries and Duracell Batteries.
You can make your AA battery last longer by keeping the batteries cool, turning off any gadgests or devices using the batteries when not in use.
You can also buy longer lasting AA batteries or use rechargeable AA batteries which cost more upfront but can be reused several times.
When it comes to the best and longest lasting battery nothing outlasts Energizer Ultimate Lithium AA batteries.
The Energizer Ultimate Lithium batteries are not only the #1 longest-lasting AA batteries…they are complete with leak resistance and performance in extreme temperatures (-40ºF to 140ºF or -40ºC to 60ºC).
If your AA batteries are draining so fast then it could be that your batteries are not good enough and you need a better longer lasting AA battery.
Some batteries have smaller amounts of power in then than others.
Or your device is a power hungry device that drains the batteries.
Also the chemicals and the plates inside the AA battery will eventually corrode over time which renders the battery powerless.
So if you have older batteries they may not last as long.
The average life of AA batteries is 3 to 5 years when unused and 24 hours when in use.
The average life of a AA battery in use is 24 hours to 28 hours depending on what it is being used in.
Unused AA batteries do eventually go bad and all batteries including the AA batteries have an expiration date.
The AA battery may still work after the expiration date but it will not have as much charge and will not last as long as a new battery.
Most AA batteries as well as AAA and C and D cell batteries will last up to 10 years unused and 9 V batteries last up to 5 years unused.
A battery is a chemical product which produces electricity by chemical reactions at its inside.
When the battery has passed the recommended usage period, the components that make up the battery will deteriorate, leading to performance degradation.
That is why there is an expiry date on the battery.
This loss of capacity (aging) in batteries is irreversible.
As the battery loses capacity, the length of time it will power the product (run time) decreases.
Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage.
Routinely check the battery's charge status.
AA batteries start off with 1.5 volts of energy, but the voltage goes down as the batteries are used up.
Once the batteries dip below 1.35 volts, they appear to be dead, even though they still have a lot of juice left.
