This is a new one for me. Didn’t do anything differently than any other year when I put the boat away this winter. Topped it off on the charger, disconnected, and let it sit. This Interstate 27dc lives in the bow compartment for the trolling motor. Cracked open the hatch today to put the battery on the charger and found a leaky mess of partially frozen fluids in the tray and on the carpet around the tray. The battery is swollen and the case split open in 4 separate areas. Any ideas? I’m thinking trapped gasses, internal short circuit, boom? No signs of damage or debris anywhere else in the hatch though. Guess I’ll be bringing the batteries in the house for the winter from now on.
