      Location: Missouri | I recommend this brand. BatteryMinder http://www.amazon.com/BatteryMINDer-Charger-Maintainer-Desulfator-M...
I have three of them I bought several years ago. It charges and pulses the battery to break up the "scale" that shorts the battery cells internally. Once charged, it floats to maintain optimum storage voltage. Over winter storage I rotate the three between the atv's, tractors, horse trailer, and truck. |
