OptiMate 4 Quad Program Gold series: 9-step 12V / 12.8V 1.25A sealed battery saving charger & maintainer

The OptiMate 4 Quad Program is a versatile, fully automatic battery charger and maintainer that independently services up to four 12 V lead‑acid batteries. Ideal for motorcycle dealerships, workshops, RVs, boats, ATVs and fleet applications, it delivers smart charging, recovery and long-term maintenance in a single rugged unit.

Each of the four charging outputs delivers 2 A constant current and runs a complete 6‑step charging sequence: recovery, bulk charge, absorption, optimization, test and maintenance. Independent circuits ensure safe connect-and-forget operation for multiple batteries without cross-interference. The charger recovers deeply discharged batteries from as low as 2 V and automatically recharges any battery that is being used or discharged.

LED indicators show charging status and battery health for each bank. Built-in temperature compensation adjusts voltage and current for ambient conditions, improving charge precision. With a sealed, weather-resistant IP54 enclosure and operation range from –40 °C to +40 °C, it’s engineered for harsh environments. A low standby draw (< 0.5 W), spark suppression, reverse-polarity protection and automatic shut-off enhance efficiency and safety.
