As the sealed care-free batteries work on "Recombine-gases to make water to replanish lost water during charge/discharge process; if the rate of charge/discharge is too high for long time the recombine process can not do as fast as the gases are produced, hi pressure will develope causing leak or even burst/ bulge of Caese.

This normally in Overcharge conditions where the charger is a simple rectifier type & does not go to trickle-charge after full-charge is obtained by battery.
