This is the third Concorde RG-35AXC in 13 years of ownership. :: the first was in the airplane when I bought it. :: The second I installed in September, 2011, and consistently used the bespoke desulfating BatteryMinder by VDC Electronics -- except that sometimes when in for maintenance my request to keep the charger hooked up was forgotten. Maintence is *hard* on batteries because the master switch goes on and off many times through the days or weeks, and this, without recharging, causes loss of capacity and sulfation. Finally, in August, a mechanic failed to start the engine properly after maintenance and ran the starter until the battery was flat. Despite the BatteryMinder, the battery had lost so much capacity that the starter labored to turn the engine. So... 2 after 2 weeks short of 9 years of service, I replaced the battery. It was 5 weeks past manufacture, so I put it on the BatteryMinder before I put a load on it. The engine turns over just fine... I expect good service from this one as well.
I have been using Concord batteries since 2001 when I bought my first airplane I believe they are better than the other major brand and I get at least 6 years service from them. Aircraft Spruce delivered the battery quickly after my order and shipping was included in the price which was very reasonable.
Excellent product delivered in a timely manner with no errors made by Aircraft Spruce. Met my expectations and the battery is fully operational. Good Job!
Replaced identical model installed in 2011. Almost 10 years of service. What more can you ask for?
Super fast shipping!
Everything went as planned. Battery arrived safe and secure in a few days.
It starts my O-540 engine and takes a charge from my alternator. What more could you want?
Price was less than Amazon, delivery was quick and on time. Plane was back up in short order. Very happy
Battery came almost immediately (2 days) and was in perfect condition. Great company!
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
No, trickle charging this battery should cause any harm to the battery.
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.
The cold crank amps rating is 440.0.
Concorde recommends the battery minder part number 11-07739 for charging, this is an 8 amp charger.
Yes, they are the same size.
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.
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.
The cold crank amps rating is 440.0.
Yes, per the application chart, the RG-35AXC should be the correct battery for your aircraft.
