15 years ago I was paying $100 for a Gill in my 182. 10 years ago I opted for this Concorde RG-35axc. I will repeat that purchase next time I need to replace the battery. More starting power than the old wet cell. I have had the plane sit in the hangar for 3 months in Idahos cold winter, started right up after sitting that long. Also after ten years it performs at least 90% of new, not ready to swap it out yet, very long lasting. Expensive? Sure is. Worth it? damn right.

I recently just replaced my previous RG35 sealed battery with another one and I am very satisfied with my choice. The old battery was showing signs of age and it is definitely noticeable with the new battery and how rapidly it spins the prop and maintains a proper charge. As long as I own an airplane Ill always use Concorde Platinum Series sealed batteries.

I just replaced my first RG-35AXC with a second one after 10 years of use. It was still cranking the engines on my Seneca II albeit a little more slowly than when new. But after 10 years, I think I got my moneys worth. It never let me down once in 10 years. Hope to get 10 years from this one. Didnt hurt that I always kept a battery minder on it in the hangar.

Have had very good luck with these batteries. No battery fluid spillage or evaporation. Cranking power is always there. I strongly recommend it!

My last Concorde RG-35AXC battery lasted 6 years. They are good batteries with no service required and no leaks. Aircraft Spruce shipping speed was excellent. Thanks

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?

Yes, the application is the same for both RG-35A and the RG-35AXC. The XC model is extra cranking and provides the highest cranking power and capacity in the 35 line. It is commonly used in cold weather applications.

Q: What are the dimensions of this RG-35AXC battery? I want to make sure it fits in my battery box.

Please see the link for the "Download RG-35AXC Diagram" in the 'Overview' tab of the web page. The dimensional drawing is included in the PDF.

Q: What is the CCa of the RG-35axc?
