Exploding Battery

It is a well-known fact that the battery could explode and even start a fire.  I’ve seen many exploded battery, still never encounter a fire started by a elec’ device = When its fails, such as a short-circuit or a component failure, it makes a big bang (exploded electrolytic capacitor may make a lots of mess = blow out a chemical) = the circuit was burnt out therefore no more power to start a fire. (so far)

The photo here above was a Ni-MH Rechargeable Battery which has been exploded with big bang  (= blow out the hydrogen gas) !    The battery itself came from Lidle with a price of  £2.99 for 4x AA (said to have 2500mAH !) —– We can’t expect a quality from such a price but the manufacturer needed to get lid of the dead-stock which was rejected by the good vender or brand, even for a scrap price — still I didn’t anticipate an explosion.  I’ve seen many coin type battery exploded but this is the first time to see AA type exploded in such severe way. 

In this case, I was near by and disconnected the charger from the main at once.   But if it was happened while I was away, it could be rather dreadful to be happened ! (Don’t leave the battery in a charger while it was ON not attended.)   Be careful.    Prepare for the worst.
