Hot Starting Battery...funny smell when charging??
I have a 2 battery system...1 starting battery and 1 deep cycle. The starting battery was dead and I was not sure how...so when I motored to Catalina I thought I'd charge it...so I left the switch on Battery 1 to charge it. About 3 hours in, we noticed a smell, looked at the batteries and there was smoke coming from the terminals, and it was HOT...switched to the 2nd battery for the rest of the trip...no issues. I just moved to a slip, and I was charging the batteries from shore power to make sure it was indeed the battery and not something else. Same issue. I plan on replacing battery 1...battery 2 the deep cycle works perfectly...can I assume that Battery 1 is toast from just age? Its at least 8 years old...probably more like 10. I'd hate to buy a new battery and fry it for other reasons...
