Why do batteries explode in flashlights?

Why do batteries explode in flashlights?

If H2 accumulates within batteries or battery compartments without sufficient release, the buildup of pressure can cause the battery or compartment casing to rupture. Also H2 and oxygen (O2) mixtures are highly explosive, and if ignited by a spark or excessive heat can produce powerful explosions.

What should I do if my battery holder is corroded?

4. Dispose of the batteries in a plastic bag. Next thing to do is to remove all of the corroded terminals. It can be tricky sometimes to do this if they are severely corroded as bits can break off and the grooves in the battery holder can get clogged-up.
