Whats everyone do for winter with their race car battery? in short I have a wet cell 16V turbo start..charged occasionally last winter and just before I went out in the spring, end result was the battery did not have any stamina. Once back at home, discharged completely then recharged, discharged recharged once again and it was fine the rest of the year. Should I leave it on the maintainer all winter? or let it die and cycle it again..or?
