OptiMate 7 6V/12V 10A Charger & Maintainer for Deep-Cycle Batteries

The OptiMate 7 is built for deep-cycle batteries in your RV or other craft, with selectable 6V or 12V charge modes to match your lead-acid battery. Three charge levels for each voltage let you fine-tune for flooded, sealed AGM, or lead-calcium batteries.

Ampmatic charge control automatically adjusts the charge rate to the battery size, giving smaller batteries less current and larger ones more, while temperature compensation keeps the battery from being over- or under-charged. A safe selection feature won't start charging if the battery voltage doesn't match the chosen mode, and the charger can recover deeply discharged batteries from as low as 0.5V. Once set, it's safe to leave connected for months.
