OptiMate 4 Quad Program 12V 1.25A Battery Charger and Maintainer
The OptiMate 4 Quad Program handles whatever battery chemistry your motorcycle runs, covering the full lifecycle from deep discharge recovery through top-up maintenance with equal precision for lead-acid and lithium LFP. Its nine charging stages adapt to the battery’s real-time condition rather than following a fixed timer, which protects cells and extends useful life across many seasons.
Key Features
- Dual-chemistry program charges both 12V lead-acid (4-60Ah) and 12.8V/13.2V lithium LiFePO4 (2-15Ah) batteries without manual switching
- 9-step automatic program includes deep-discharge recovery from as low as 0.5V for both lead-acid and LFP chemistries
- BMW CAN-bus compatible via programs 2 and 4 – charges through the factory 12V socket on CAN-bus controlled BMW motorcycles
- IP54 weatherproof and rated to -40 C/-40 F for year-round outdoor use in all climates
- LED diagnostic display indicates battery condition and charge status throughout the program
- Float maintenance mode keeps the battery at full charge safely for extended storage periods
