The OptiMate 1 VoltMatic is a simple, set-and-forget battery maintainer that recognizes 6V and 12V lead-acid batteries on its own, so it's just as happy on a vintage 6V bike as it is on a modern 12V one. It delivers a steady 0.6 Amp, never overcharges or undercharges, and keeps a stored or seasonal bike's battery ready to go.
Its 4-step program starts from as low as 4V, charges and then maintains the battery around the clock. The plug-in case goes right in the wall outlet with a long 12 ft charge lead to reach the bike. It's for lead-acid batteries (flooded, AGM, GEL); for a lithium battery choose the OptiMate 1 Duo.
