OptiMate 3, the all in one tool for 12V battery care at home. Diagnoses, recovers, charges, tests and optimally maintains, automatically. The latest version of OptiMate 3 retains all easy-to-use characteristics of the over 2 million OptiMates produced since 1995, but is now lighter and more efficient than ever. The OptiMate 3 recovers sulphated batteries and then tests after charging. The maintenance program delivers only what the battery needs, never overcharges, never undercharges.
If you own a snowmobile, atv, motorcycle, lawn tractor, and you want to keep the battery fresh, you need one of these. They work great and are very easy to use. It will pay for itself many times over. I have batteries that are over 8 years old and still work like new.
