OptiMate 5 Select 6V/12V Charger & Maintainer for Deep-Cycle Batteries

The OptiMate 5 Select is designed to optimize performance and extend the life of 6V and 12V deep-cycle batteries in your RV or other craft, and it also works great for any 12V starter battery in cars, trucks, ATVs, or motorcycles. Select the right charge voltage for flooded, sealed AGM, GEL, or lead-calcium batteries.

Your charge-mode selection stays in memory even if AC power is lost, and a safe selection feature keeps you from accidentally charging a 6V battery in 12V mode. Ampmatic charge control with built-in temperature compensation adjusts the rate to battery size, condition, and ambient temperature, and the 8-step program recovers deeply discharged batteries from as low as 0.5V before switching to long-term maintenance.
