OptiMate 6 Select Battery Chargers

The OptiMate 6 Select battery chargers are designed to optimize performance and extend the life of 12 V battery in your car, pickup truck, ATV, speed boat or motorcycle. These battery chargers also work great for your RV! The automatic 9-step program saves a deep discharged battery from as low as 0.5 V with Optimate's smart DE sulphation modes recovering the battery, so that it can once again accept charge, all automatically. Once charged, Optimate's 24-7 long-term maintenance mode keeps battery at its optimal level, ready to start vehicle or craft.
