List' Ditto for me also, I've had my optima batt for 9years now and no problems of any kind. I do use a small Harbor Freight "float charger" (#42292-1RHH $9.99 or sometimes on sale $4.99) that I keep on all of the time. It's not a charger; it only keeps a small charge of 600ma at 13 or 14 volts, but it does the job. Jerry Christopherson 9473187
