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

The battery minder in my opinion is a must for aircraft owners/operators. I use this model on a turbine helicopter (for 6 years) and various airplanes (most recently a Cessna 206H). I have used the battery minder for over 5 years and have seen my battery life extended by almost twice the normal interval. The price is reasonable, when you consider the cost of replacing poorly maintained batteries

The charger gives a real time condition check for the battery. It also includes a desulfurization

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

Keeps both batteries charged and disulfide.

As advertised -- no hassle, no worry. Trouble-free charging, and it does make a difference. Having confidence on every start is a good thing.

I bought a Cessna T192T ordering charger to keep battery maintained ready to fly. Battery (located in tail fuselage of plane) was found to be a Gill battery during annual / not pre-buy inspection; Concorde battery’s have different voltages, thus charger could not be used with Gill battery. I called manufacturer in New York, I was informed unit could be returned, for a nominal fee they would reprogram to work with Gill battery. I sent unit to them (brand new, power cord still factory coiled and tie wrapped). I rec’d a phone call a few days later with questions about return, why, any problems, etc. I explained my stupidity in not knowing battery when unit ordered; gave my CC, a few days later I rec’d a new correct charger for my battery. Great service from manufacturer, very supportive and very fair in working with me as my time had lapsed for returning unit from time I purchased airplane to annual date. Cannot sing praises enough for how unit works nor how I was treated with adjustment to secure correct charger for my Cessna T182T from the producer / manufacturer. Best charger and service in market today.

Keeps my airplane battery fully charged and ready to go.

After upgrading our avionics we needed to make sure our batteries were taken care of. It works great

Excellent product!! Made specifically for the Concorde battery. I like the desulfate cycling. It keeps the battery charged and in top condition. With expesnse of the batteries, having this charger seems to be a great investment.
