The OptiMate 3 2-Bank puts two independent OptiMate 3 chargers in one weatherproof case, so you can charge and maintain two 12V lead-acid batteries from a single wall outlet. Each bank delivers 0.8 Amps and runs its own fully automatic 7-step program: diagnose, recover, charge, test and maintain.
The banks are electrically isolated, so each battery is handled on its own, and you can even charge batteries wired in series. It's the easy way to keep a garage full of motorcycles, ATVs, PWCs and mowers ready to ride. For lead-acid batteries only; for lithium, see the OptiMate Lithium 4s 0.8A 4-Bank.
