Description
Lithium battery technology demands intelligent charging—and standard chargers won’t cut it. The TECMATE Optimate TM391 is purpose-built for lithium (LFP) batteries, delivering precision charging that balances cell voltage, recovers deeply discharged packs, and maintains optimal battery health. Whether you’re storing a race vehicle between seasons or maintaining a daily driver with a modern lithium setup, this charger ensures your battery stays in peak condition.
Unlike conventional chargers that can damage lithium cells through incorrect voltage profiles, the TM391’s multi-step program and Ampmatic technology automatically adjust charge rates based on your battery’s capacity and current state. The included TUNE mode gives you stable power for diagnostics and troubleshooting without firing the engine—invaluable for electrical system work.
