KyDan good solution
We do the same as KyDan. I have numerous Battery Minders going at all times on occasional use machinery; motorcycle, tractors, RV. My batteries last "forever" and are always at peak performance. My tractor batteries go 8 to 10 years using this product; really . . . my motorcycle battery is 7 years old. no problem. awesome product. has anti-suffation technology too.
