This specially adjusted BatteryMINDer PLUS® is designed to maintain Optima, Odyssey and all known brands of AGM sealed "dry" batteries at full charge, without ever overcharging. Special adjustment ensures complete compliance with battery manufacturer's exact specifications for cyclic long term non-use storage. One (1) Amp (constant voltage) maximum current, when battery is at less than full charge when first stored, complies with AGM battery maker's requirements.

The AGM/Optima BatteryMINDer PLUS® goes two steps further than any known maintenance charger. Using Pulse Width Modulated (PWM) circuitry the unit supplies each battery with just the amount of current needed to raise or maintain the battery's voltage at full charge level. Second step is the full-time automatic process that safely removes harmful sulphation. By using U.S. patented pulse mode technology it dissolves the crystals of sulphate that prevents the battery from delivering its full power and cycle life. It does this without raising the output voltage above the battery maker's maximum recommended voltage levels. Keeping the battery free of sulphate virtually guarantees to significantly increase your battery's life and performance. All units are individually adjusted to ensure compliance with each battery manufacturer's specifications.

VDC Electronics guarantees a sulphate-free battery over its entire life-time or you will receive 100% of your money back. This guarantee is in addition to a five (5) year "no hassle" warranty.

NOTE: Model 12118 AGM/OPTIMA BatteryMINDer PLUS® should only be used on AGM type sealed batteries, not "filler cap" liquid batteries, due to its special voltage settings. This unit is designed primarily as a maintenance charger for long term, safe storage charging of Optima and other similar AGM type batteries, not as a primary or general charging source.
