Overcharging or short-circuiting of the battery is the only reason for swelling up of the lead acid battery. When a battery gets older its chemicals start to undergo chemical reactions that produce a gas. A swollen lithium-ion battery may catch fire or explode. On the other hand the battery can chemically react in a way that causes solid material to build up inside.
