BatteryMINDer 244CEC2-AA-S5: 24 Volt-4 Amp Concorde Aviation Battery Charger, Battery Maintainer, and Battery Desulfator

I got the 24 volt Battery Minder to keep the Concorde battery in my airplane charged between flights. I just works - no problems so far. I keep the battery plugged in when the airplane is in the hangar. So far no signs of over or under charging. I have had it around 3 months now. We will see if it lasts.

Keeps both batteries charged and disulfide.

Keeps my batteries charged between flights. Very happy with the purchase.

I purchased this for my airplane battery and it works perfect. I have owned these in the past with never an issue.
