One of the best batteries on the market. If you are a piper owner, please read the STC list carefully, older cherokees ned the RG-35, newer cherokees use the RG-25. Dont get this confused or you will make costly mistake that is not Aircraft Spruces fault.

I ordered this battery because it was the only group 35 in stock. I paid more than the Gill but this really spins the prop on start. Installation in a Piper required the removal of the wood hold down in the original box but that wasnt a big deal. Hope it lasts a long time.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

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.
