For sale, used, 1 BatteryMINDer 12V 2/4/8A Battery Charger / Desulfator Model 128CEC1. This can charge and maintain most deep cycle (Boat / RV), airplane, or car batteries, as long as they are 12V. This can also desulfate, which is an important feature when maintaining most batteries. This can charge at 3 speeds - 2A, 4A, or 8A. You can select Oddssey / PLT, Wet / AGM / Sealed (Lead Acid), or GEL type batteries for charging.

I was using this to maintain an RV Sealed Lead Acid Battery unit I upgraded to a battery type that did not need maintenance charging (LifePo4).

Item is in like-new condition, wall mountable (though this does not include hardware for it), and works great!
