AGM Battery Charger Recommendations
Indian Motorcycle recommends using the BatteryMINDer® 2012 AGM - 2 AMP battery charger (PN 2830438) to charge and maintain AGM batteries. The charger can be found on the Indian PG&A website. If not using the BatteryMINDer® 2012 AGM - 2 AMP battery charger, an automatic or constant monitoring AGM battery charger with a charging rate of 2 amps or less is recommended to prevent damage to the battery.
Batteries that fall below 12.5V run the risk of sulfation, a condition whereby sulfate crystals form inside the battery and significantly reduce performance. AGM chargers are designed specifically for charging AGM type batteries and use high frequency pulses to partially reverse sulfation.
