Lithium-ion (LiFePO4) batteries take a charge in a different way from lead/acid batteries. Attempting to use an automotive or motorcycle charger intended for lead/acid batteries can permanently damage a lithium-iron battery. The OptiMate brand is a technology leader well known for high-quality battery chargers. That is why we are pleased to offer the OptiMate Lithium charger specifically designed for LiFePO4 batteries. This charger will safely test, charge, and maintain lithium-technology batteries, protecting your investment.
Note: YANMAR models that come stock with a Lithium-Ion battery require this battery charger for battery activation and maintenance.B&S Enterprises, Inc. your Yanmar Dealer Sales, Parts and Service Technicians- Ready to handle any requests or issues to keep you going.
