you may think i'm crazy but now i have NINE. Generator, two boat batteries, two garden tractors, a motorcycle, two cars and a sump pump. I literally paid the price for not maintaining lead-acid batteries. And today, one of them is close to $100. Since I don't travel much, the batteries don't charge and all self-discharge, especially with age. The more you leak them, the more they sulfate, the faster they die, and then you have a (forever) dead battery and can't go where you want to go. garageโฆ
