+ | The question is this: **what voltage can starter batteries be held at without damage**? | ||

+ | ==== staged charging ==== | ||
+ | |||
+ | CTEK's starter battery charger designed to be left on charges thusly: | ||
+ | |||
+ | * 14.4v Absorption | ||
+ | * 13.6v Float | ||
+ | |||
+ | So a smart charger fitting that profile should be gentle enough on the battery. | ||

+ | ==== single voltage charging ==== | ||

+ | * folks who shallow cycle might charge to 14.4v to help counteract the cycling | ||
+ | * folks who non-cycle might charge to 13.6v as if the battery is simply being maintained. | ||
