Product InformationStore Part Number: 28252-AA


BatteryMINDer Model 28252-AA supplies up to 25 amps of ground power from 100-240 VAC, as far as 300 feet (91.44 meters) from the source. Recently featured in Light Plane Maintenance Magazine (Paradigm Shift Charger), Approved by the major aircraft battery manufacturers in the U.S., it safely charges both sealed and wet cell 24 Volt LA aviation batteries in as little as one (1) hour. Dedicated desulfation, optional equalization and long-term float (maintenance) mode help recover lost capacity enabling many marginal batteries to pass the FAA airworthiness test. Power supply mode enables use of glass panel displays and other avionic electronics without draining your battery. LCD panel shows battery voltage, amperage, temperature, time and amp-hour acceptance. 

Using an array of microprocessor controlled sensors, BatteryMINDer Model 28252-AA actively monitors your battery's voltage, amperage acceptance and temperature at all times. Working through a series of charging and diagnostics stages, the internal program adjusts its output several times a second, based on sensor reading, to quickly and correctly charge your battery. When used as a maintainer, the BatteryMINDer is guaranteed to maximize your battery's life and storage capacity. The Temperature compensated long-term float (maintenance) stage can add years of service, and patented high frequency sweep pulse desulfation is designed to reverse and eliminate battery sulfation, the #1 cause of early battery failure.
