I live at south western Arizona and get 6 years of service out of these Concordâs. The cheaper brands last 3 at most. They are expensive but wonât leave you stranded at a strange airport without warning!
Excellent service, as always. The product arrived promptly and was installed on my aircraft that day.
Just got it. Easy install, works fine, hope it will last a long time.
Best battery on the market. I requested the STC application from Concorde, sent it back and within 15 minutes it was in my inbox.
Best battery for my Bonanza
I have had airplanes since 1999. My previous batteries never lasted more than four years. My current airplane has had a Concorde battery installed since 2012 and its now just starting to fail. I am happily ready to purchase a Concorde replacement.
The battery, of course, was perfect. The delivery was exceptional. I had the battery in my hands in 2 days. Could not have been better.
highly competitive price, free delivery, tracked delivery that was on time. Awesome
Battery came on time and is working as advertised. Concorde makes a good battery
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.
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.
