TECMATE Optimate 4 - Quad - Premium Edition TM631PR

Keeping your battery in peak condition between rides is just as critical as maintaining your engine—neglect it, and you're looking at premature failure, weak starts, and shortened lifespan. The TECMATE Optimate 4 Quad Premium Edition is a fully automated, set-it-and-forget-it charger designed for serious riders and racers who depend on their vehicles. Whether you're storing a bike for winter, maintaining a fleet, or keeping your battery healthy year-round, this charger combines smart desulphation technology with lithium LFP compatibility to handle both traditional lead-acid and modern battery chemistry without supervision.

What sets the Optimate 4 Quad apart is its ability to select your specific battery type and let the integrated microprocessor handle the rest—no guesswork, no overcharging risk, and no damage to delicate lithium management systems. The included O-19 DIN socket adapter makes it compatible with BMW and Triumph motorcycles right out of the box, while the weatherproof IP54 rating means reliable performance in any garage or outdoor storage setup, even in extreme cold down to -40°F.
