Tecmate TA-31 Optimate Pro 1 Duo

Charger, tester and power supply for 12V lead-acid and 12.8V lithium batteries. Power supply function allows for tuning and running diagnostics while the engine is off. Automatic fast new battery activation. Smart recovery mode for deep discharged batteries. Push-button Battery Management System (BMS) reset. The high-voltage and pulsing recovery mode is able to save a neglected sulfated 12V lead-acid battery unable to accept charge from a standard charger. Battery power is optimized during bulk, absorption and cell balancing charge modes by the microprocessor-controlled Ampmatic program, a unique feature that automatically ensures the battery receives optimal current every second, and then tests to verify charge retention. Automatic safety features include quick identification of a severely shorted battery, 12-hour maximum program for used batteries and electronic reverse-polarity protection.
