Wonderful battery that has never let me down. Never, and my first one was badly abused charging with car chargers and depleted to below end voltage on a long flight with a dead alternator. That battery still lasted five years before a cell died. It still started the engine just fine, but it would not pass a capacity test. Nine years later it is still good enough to run the 2000 lb hangar winch once in a while. Along the way I set the ship's alternator to the owner's manual recommendations for summer and winter voltages (14.2 - 14.4v for my average temp). It is also babied because I use the VDC BatteryMinder 12248-AA-S1 and now the -S5 charger/maintainer continuously when the plane isn't flying. I also have a solar charger from VDC for when its parked on the ramp somewhere. The thought isn't to save money: It's to have a reliable battery. The second battery is just turning four years old and still passing the Concorde capacity test. It has been babied more than the first so I expect it will last longer than the first, which beat the competition by about 2x at a similar cost. A word of warning: AGM/RG batteries do not tolerate abuse as well as flooded. Boil a flooded and you can refill it. Boil an AGM and it's toast. Ditto undercharging. To get max life you have to be a bit anal. |

Is this battery a drop-in replacement for my current Gill battery in my 182? Or will I be required to: 1) purchase a volt meter to determine if it is charged. 2) get a torque wrench that measures inch pounds to ensure the terminals are not over torqued. 3) have an a&p ia do the paperwork to approve the install 4) modify the battery box lid so it closes properly 5) get a special trickle charger that works specifically for this battery. As an owner, I just want to replace the battery and go fly. Regards, Greg
Yes, this is a drop in replacement for this aircraft. 1) We maintain the charge in the batteries while they are in stock. A volt meter is a good way to determine present state of charge. 2) Please do pay special attention to avoid over-torquing. Torque information comes with the battery. 3) You need to contact the local FSDO for this question. per the manufacturer, we have an STC and PMA. The STC is available at no charge. Per Concorde, they just need the information sheet completed and they can can email for free. 4) Some installations do require modification of the battery box cover. This is covered in the STC. 5) We only recommend the BatteryMINDers listed under the "Accessories" tab of this web page
Will it hurt this battery to trickle charge it? RG-35AXC
No, trickle charging this battery should cause any harm to the battery.
