Golf Cart Battery Lifespan Question
Bought my six Johnson Controls golf cart batteries at Sam's Club three years ago. Other than a handful of discharges to the 75% SOC just to test them, they are almost virgin. Verified again today that they'll still run my 3/4HP well pump through my 6-Kilowatt MSW inverter & a GE-1.5Kw 120v:240v Transformer. How much more lifespan should I reasonably expect to get out of them?
