A 5-stage constant current-voltage charger/maintainer/desulfator, the VDC Electronics BatteryMINDer is an ideal choice for handling 12V and 24V battery charging requirements. Microprocessor controlled, this system works for all sealed, AGM, Gell and flooded (wet cell) lead-acid batteries. Actively monitors a user's battery voltage, amperage acceptance and temperature at all times, and works through a series of charging and diagnostics stages. The temperature compensated long-term float (maintenance) stage can add years of service, and patented full-time high frequency sweep pulse desulfation is designed to reverse and eliminate battery sulfation.
