Concord is an excellent battery !! I changed mine out with 5 years in service and still starting my twin good. I have heard of Concord batteries going but for the price and dependability you can’t go wrong.

An exact replacement for a 5 year old concorde Rg-axc which was getting sluggish but still firing up my Beechcraft Sundowner. Arrived from ACP East to Tallahassee, Fl., in about 3days, faster than a letter! I left a note to leave on the step so I would not have to carry downstairs. Concorde provides good long service and is about good as they get. Have been buying from AirCraft Spruce when they started out mostly selling spruce, dope and covering supplies near the Griffen airport. Great Company!

My 3rd 35axc. First one went 5years so I replaced it and it’s still going strong on my Polaris Ranger. 2nd one failed at three years. Disappointing but it happens. I have high hopes #3 will be a 5year battery.

I wish my experience was the same as many here. I purchased this battery from Aircraft Spruce 10/4/17. Now (7/11/19), approximately 20 months later, its dead. Replacing with same and hoping for better results.

Battery failed in 20 months 100 cycles. Correct battery minder in use, no unusual environmental conditions (Virginia) or equipment (Cessna 180). Concorde advised that credit under warranty would be $50 +/- for a $340 battery. They sent me to Aircraft Spruce as distributor, who has a warranty card on line with no mailing instructions so I have to wait for someone to call me back with mailing instructions! This isnt my first rodeo. Been flying 50+ years and owned all or part of seven airplanes over than time.

The battery is my standard but getting it from Aircraft Spruce makes it a no-brainer. Fast, cheap, and easy.

Q&A

Q: 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

Q: Will it hurt this battery to trickle charge it? RG-35AXC

No, trickle charging this battery should cause any harm to the battery.

Q: I just purchased a Concorde RG-35 AXC battery. In the Q&A section, it says an STC is available at no charge. How do I go about obtaining the STC?

There is a form that is available in the "Documents" tab. It is the first one listed. Please download it, fill it out, and send it to Concorde and they will send the STC at no charge.

Q: What is the CCA rating of this RG-35AXC battery?

The cold crank amps rating is 440.0.

Q: I've had the RG-35AXC for about2 1/2 years now and haven't been flying to much lately, plane has been sitting for almost a year.. I try to go out and start and run the engine once a week or so. The temps here in Miami and rather high, I mean HOT. anyway the battery appears to be really low and won't turn over the engine. What is the best way to charge it back up...right now I'm using a slow 2amp charge or should I boost that up higher???

Concorde recommends the battery minder part number 11-07739 for charging, this is an 8 amp charger.

Q: Are the Concorde RG-35A and the RG-35AXC batteries the same physical size?

Yes, they are the same size.

Q: Is the RG-35AXC a drop-in replacement for the Concord RG-35?
