The OptiMate 4 Quad Program Premium Edition is the same 1.25 Amp, four-program charger, tester and maintainer as the standard Quad Program, with one extra in the box: the O-19 compact SAE-to-DIN adapter, so BMW and Triumph owners can charge straight through the bike's 12V DIN power socket without touching the battery.
Choose from 12V lead-acid, 12V BMW CAN-bus, 12.8V lithium or 12.8V lithium BMW CAN-bus programs. It tests the battery before and after charging, recovers deeply discharged batteries from as low as 0.5V, and then maintains the battery at full charge for as long as it stays connected.
