My first order with this company was impressive. I ordered a battery it arrived in two days, but I discovered it was the wrong one. They let me return it for a full refund and I got the correct one the next day. I received credit for the return within 3 days! These people are a great company to do business with!

The battery was just installed, so I will not be able to provide a proper review until we see how long it lasts. I do not fly daily, so I put the battery on a trickle charger after each flight to ensure the plane will start every time I go to fly it. This worked fine with the previous Gill battery. We will see how well this works with the Concorde.

We have been using Concorde batteries in our aircraft for the last seven years. It is important to keep a float charger connected when the aircraft is not flown daily and when installing this battery in a newly purchased aircraft, we added a fused charging pigtail. After a test flight which required two starts (we had to top the tanks), the aircraft was parked and a battery minder was routinely connected.
The next morning when the aircraft was going to be flown, the baterry was completely dead, despite a float charger being connected for nearly 18 hours. The battery was isolated from the electrical system and connected to a different float charger. After five days when the state of charge indicator would not indicate above 75%, a call was made to Concorde Battery to seek warranty advice.
The phone was answered automatically in a coherent manner. Selecting 0 immediately was answered by a comprehendable voice who redirected the call to another person who was equally concerned with identifying our problem. A suggestion was made to take the battery to a nearby distributor for evealuation or get an RMA to have it returned to the factory. Not wanting to purchase another battery while we waited to identify if this battery was damaged beyond repair, the battery was driven to the nearest distributor.
The distributor met us at their door taking the battery directly to the bench where testing revealed it was at 100% state of charge and possessed the necessary cranking amps to start an aircraft.
Weve not experienced this level or qualiuty of service in recent years and delighted we chose a Concorde Battery .

I just got 6 years out of my Concord RG-25 in my Grumman Tiger. It was a gentleman and telegraphed its failure by a gradual decrease in cranking power. I was still able to start the Grumman after sitting for a week, but the battery was speaking to me. I replaced it with another of the same type, and that says what I think of the battery. Much better than the flooded acid type from Gill. SC

Over last 15 years Ive used the RG batteries and have had superior service life and clean battery compartments.

I am just getting ready to purchase another Concord RG25 battery after almost 7 1/2 years. My old battery is just starting to show signs of weakness on initial start up but I never had a problem with it and never put it on charge or had to charge it.

Great Battery, obviously, Im buying another!

Darrin M
March 1, 2015
My Concorde is now 4 1/2 years and about 300 hours old, and has worked perfectly the entire time. In the winter, I periodically put a cheap trickle charger (1 1/2 amps) on it, which charges for maybe half an hour before shutting off if I haven't flown for a couple of weeks.
Cary A
November 5, 2014
We have always used a Gill. The last two Gills have died on us shortly after one year and during that time frame would have to charge it up consistently. I was always afraid of the plane not starting due to a low battery. We purchased a concord in November 2013. We have never needed to charge it. It is an extreme difference on start up in comparison to Gill. You can really just hear and feel the energy on start up. I will keep you posted but so far it is worth the extra money. We may never go back to Gill.

Good batteries, I have been flying concordes for 20 years or so. However they work, it is fantastic to have them sealed and not leaking battery acid fumes in an aluminum airplane.
Five stars basically.
I fly regularly, so dont have any issues with trickle chargers, etc. My only (and this is minor) complaint is that I dont ever stress the battery, it is charged regularly with a modern, properly adjusted voltage regulator in my plane, yet I am lucky to get 4 years out of one. I live in FL so perhaps it is the heat. It just seems like they should last longer.

I previously used Gill flooded batteries with mixed results. Last one lasted 5 1/2 years. (not bad) It was recommended to try the RG 25 because it needed no vent (a problem on my plane) and would last longer. It puked after 3 1/2 years. Will charge and show proper voltage until a small load is put on it then it goes to 3-7 volts. I had a battery maintainer on it most of its life. Now they say you need a special float charger. Battery Minder 12248-AA-5.
Im buying another RG 25 because of the vent issue but if there was a another good alternative I would change.

Mine lasted 26 months as well. It was the original from my new 2014 7GCBC. Im reordering the same battery in the hopes that it was a fluke. I too always kept the battery on an inexpensive battery tender. 1 week ago the battery stopped accepting a charge altogether. I called concorde and they prorate warrant their batteries for 24 months. They did however recommend using CEC Model No. 128CEC1-AA-S5 from battery minder for their batteries. Reviews comparing Concorde to Gill are all highly in favor of Concorde as the better battery company.
Michael H
September 12, 2016
Battery installed 12/13. Knowing plane would not be flown often, purchased battery minder (correct one) which has been connected to plane during periods of non use. Battery has started plane half a dozen times in two year span. Battery failed (short under load) 11/15. Very disappointing to pull a battery that is basically brand new in appearance to replace.

I have used Concord sealed batteries for years. The one I have now is not even 3 yrs. old and it's bad. I fly my plane weekly so it's not like the battery sits around not being used. I'm not happy about this short life cycle of this battery but I have a new one ordered and hoping it will last longer. The main reason I like this battery is that it doesn't cause the battery box to corrode.

I've gotten 30-34 months from the last four Concorde RG-25's in two airplanes. No warning, they just die unexpectedly. Manufacturer says they should last 5-7 years but so sad, it sucks to be you.
Also, watch the free battery shipping with Spruce. I added a foam filter element and it cost $21 in shipping!

Lasted 26 months and almost always kept on a Battery Minder. Disappointing.

I have been replacing these batteries about once every 2 years in my C-177. Not sure what is going on with Concorde quality?

According to compatibility chart it should work in my plane. Wrong size.
