OptiMate 1 Voltmatic: 4-step, automatic charger & maintainer Lead-acid, 6V / 12V , 0.6A

The OptiMate 1 VoltMatic (model: TM-401) is a compact automatic battery charger and long-term maintainer for smaller 6V and 12V lead-acid batteries used in motorcycles, ATVs, UTVs, personal watercraft, snowmobiles, vintage vehicles, medical equipment, security systems and other battery-powered equipment.

VoltMatic smart control automatically recognizes whether the connected battery is 6V or 12V and selects the correct charging program—no manual voltage selection required. Simply connect the charger to the battery, and OptiMate 1 automatically charges, optimizes and maintains it without supervision.

The 0.6A charging current is ideal for smaller STD flooded, AGM and GEL batteries. It can provide 24-7 maintenance for batteries from 2Ah to 28Ah and recharge batteries up to 15Ah within 24 hours.

With a low-voltage start of 4V, energy-efficient operation and proven “connect and forget” maintenance, the OptiMate 1 VoltMatic keeps seasonal and infrequently used batteries fully charged, healthy and ready when needed.

VoltMatic: Smart microprocessor control automatically identifies the connected battery as 6V or 12V and applies the correct charging voltage.

AUTOMATIC: Connect the charger to a compatible STD, AGM or GEL lead-acid battery, and the 4-step charging and maintenance program does the rest automatically.

LOW-VOLT START: Begins charging batteries with voltage as low as 4V.

24-7 MAINTENANCE: Safely maintains the battery at full charge for extended storage without overcharging.

SAFE: Fully protected against accidental reverse polarity, short circuits and disconnected batteries. Spark-suppressed operation makes it safe for sensitive vehicle electronics.

ENERGY-SAVING TECHNOLOGY: High-efficiency charging and maintenance with standby power consumption below 0.5W.
