TJ doesn’t get driven a lot, so I keep the battery on a float charger. Battery is 9 years old, though.
Last week I took it out - no problems starting, all ran fine. Got it quite wet and muddy on farm tracks with standing puddles - at times I had to go fast enough that the water splashed up over the windscreen but it was never more than 3-4 inches deep. Parked it for an hour, started up fine.
I wasn’t going straight home so I took it to a gas station jet wash to get the worst of the mud off. Stopped for an hour, it started but was a bit reluctant to start. Parked it up, put the battery on charge.
2 days later, my son went to start it and the battery was dead. Odd, as the charger said the battery was fully charged. Put it on a different charger which showed weirdly fluctuating voltage levels like it couldn’t decide what voltage to charge it at.
Dead battery all of a sudden (it is old, I guess, but absolutely fine) or did the jet wash get water somewhere it shouldn’t? If it’s the latter, where do I look first?
