I've already talked to a couple of local forum members about this subject. I have the 2 battery set up on our boat and I religiously maintain them in the off season. I usually just keep the onboard battery plugged in all winter but now that we're keeping it in dry storage they don't allow the charging or maintaining of batteries in the storage area amongst other boats. So once a month this past winter I had them take the boat out and put it at the wash rack and I would plug it in for a good 24 hours then they would put it back the next morning. (Yes, I was too lazy to take the batteries out and bring them home this winter) So this was the next best thing. Anyway, I'm coming up on the 4th season on these batteries. They say the average lifespan of a marine battery is 3 to 5 years. Just had the battery die in my wife's Cadillac and also in my lawn tractor. Both purchased in 2019! How long have your batteries lasted in your boats?!? The interstate cranking battery in my old Bennington I/O lasted 10 seasons...... Even though I have 2 batteries I still carry a lithium jump pack out of habit.....
