Had one explode on a travel trailer once, too. The battery was in a
plastic battery box on the front A-frame and had been on trickle charge
for about three months. This was in the middle of winter. It threw
shrapnel a foot or two on either side.

Froze up?

Probably. To say that the battery chargers in RV power converters are
often poorly designed would be, perhaps, too kind.
