Batteries store and release their energy using chemical reactions, that continue at a far slower rate when in storage. These reactions may very occasionally cause explosions under extreme circumstances. So the answer to your question can batteries explode in storage is ‘perhaps’ depending on how you use them.
Circumstances Under Which Batteries May Explode
Batteries explode when their internal chemical reactions become unstable. Possible causes include physical damage, careless storage, high ambient temperature, and substandard manufacturing. Any of these can disturb the chemical balance.
The resulting instability can lead to the abnormal release of flammable gases inside battery cases. These fumes can leak out and catch fire, or increase the internal pressure until the battery explodes.
Batteries can explode in storage or in use. Now you know that for a fact, your next question is naturally how to prevent this. Your first defence is to handle them thoughtfully, and not to store them under the conditions we mentioned earlier.
If a battery starts behaving differently, disconnect it from any device or charger, if you can do so safely. Put the battery on a non-flammable surface and hope it stabilizes.
But, and this is important, move away from the battery if it starts swelling, smoking, or smelling different. Call your local emergency services for advice or assistance. Do not touch the battery.
Which Batteries Could Potentially Explode?
- Regular reports in the media confirm that lithium-ion batteries can explode in storage, and in use. Cheap, substandard, and counterfeit batteries are the most likely culprits.
- Lithium-polymer batteries are in soft cases that allow for natural expansion when charging. This makes them relatively vulnerable to external damage, leading to leaks and even explosions.
- Valve-regulated lead-acid batteries emit flammable hydrogen gas when charging. These starter batteries are easy to spot, because you have to open the caps and top them up with distilled water.
UPS Battery Center’s deep-cycle lead-acid batteries are safely sealed for life. They recombine the hydrogen gas internally so you never need to top them up. This makes them arguably one of the safest, most reliable batteries on the market.
