I put the battery in. It fit. I connected the terminals properly. I then started the left engine. Then the right. The engines fired right up. I was relieved. I felt a sensation of relief and a touch of amazement that it worked and it wasnt something else within the electrical system.

This is the third RG-25 we’ve installed in our C-172. The first one lasted seven years, and the second one lasted five years. There is never any spillage or need to repair the battery box. In my estimation this is the least expensive and most reliable battery money can buy.

David P Verified Purchase

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.

Previous Concorde RG 25 lasted a week short of 6 years. Would probably have lasted longer if I had not forgotten and left the master switch on. A little expensive but the best battery I have ever had in my plane. Worth it if it lasts as long as the dead one its replacing

These batteries are very good. Shipping was fast . Good value.

Ordered the battery one day and it arrived the next by UPS ground.

very satisfied with concorde batteries. long life, reliable performance

You guys, are the best thing going , for general, aviation !!!!!!!!!!!!!!!!!

Aircraft Spruce showed their normal high efficiency and shipped immediately. The battery arrived well packed and fully charged. Im very satisfied with the whole process.

Excellent battery, the no spill and no maintenance does the trick. I am not sure if Gill has the same battery or not, but if they do Ill get it next time. Its too much money for a piece of led and plastic.

Product was delivered in a timely manner and in excellent, functional condition.

Fast shipping, very good product

Our previous RG25 lasted nearly 5 years, which seems good for the Florida heat. This battery arrived charged [OCV 12.9] and cranked well. So far so good. Great service from Spruce also, it only took 4 days from order to delivery.

Excellent!

I needed a new Concorde RG-25 for my Alon A-2 Aircoupe. Aircraft Spruce managed to get one to me over the weekend with free shipping. I live in East Texas, and Spruce had the battery shipped from Dallas. Amazingly fast delivery and this, during the virus pandemic.

this battery has the cramking power I nrrded, works just fine.

Bought 2 of these for a Cessna 310.. installed easily with no problems.. they were fully charged and started the engines right up.

I am very pleased with the service from Pilotshop, very dependable with the order and shipping, The battery seems to be very dependable also, time will tell on the duration, Thank You

Battery is perfect for my Cessna 150L

Really love the idea of no acid leaks.

Great Battery. Came delivered in excellent packaging, timeliness and with a full charge. Lycoming O-360 started right up.

Great battery .. purchased as a replacement for the current RG-25 after good experience with Concord. Very satisfied with unit and Spruce had it shipped in 2 days.

Concorde RG-25 last one lasted 5 years, hope this does also!

As always, battery was delivered promptly. Thanks Aircraft Spruce.

Emailed the order...showed up in a couple of days....problem fixed.....no inconvenient trip to buy one locally

Great battery, last one made it 5.5 years. Ordering from ACS was very efficient, got it two days later.

Great Price and Fast Shipping!

Filled order the same day. Received the next day. Great service!

Good service

I have purchased these over the competition because of their higher cold cranking amps.

the product arrived sober perfect, thank you very much

fast shipment, a quality product

Ordered in the afternoon, arrived next day before noon. Great service !

I ordered the battery through Amy Stinchcomb Monday morning and it arrived Tuesday by 2:00pm. I ordered other parts through Amy the next Monday and they arrived Tuesday before noon.The products were delivered without a shipping charge... A real plus. Amy, the products and the service all rated 5 stars.

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 .

The battery showed up a couple days after ordering. Came fully charged and ready to go. I thought Id have to put it on the charger over night to get it full. Working great.

Bought this to replace the one that had been in my airplane for over 8 years. Two day service is outstanding.

Battery arrived fully charged and ready for install. Fit perfectly. Provided all the power it was supposed to provide.

Concorde batteries have always provided the best service and reliability. Several years ago I replaced the battery in our 172 with a Gill battery, A&P recommenced, and it gave up the ghost within 5 months. Company would not honor any warranty and I got a Concorde to replace it and have stuck with them ever since.

I just replaced my 8+ year old Concorde RG-25 battery with a new one. I hope it lasts as long as my old one. The engine now starts really quick! I couldnt be more satisfied with it.

My 2nd RG-25 battery. Easy to install and works great. Delivery from Aircraft Spruce was free and quick. My previous RG-25 was 5 years old and still working but getting a little weak.

I am now replacing my RG25 after just short of 10 years. Once in awhile I will put a Battery Minder on it for a few hours if I havent been flying for a week or so. But I never leave a charger on it over night. I dont think these batteries like having any kind of charger on them for long periods. Very pleased.

As usual same great service from Aircraft Spruce and drop in replacement for my previous battery. Last battery lasted only two years, but that was after I left a map light on and completely drained it.

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. As long as the other electrical system components are serviceable these batteries should last a minimum of 5 years. I always keep ours on a battery minder when inactive, you may want to also.

Last Concorde lasted 7+ years of abuse - never tended, sat unused for 1 year - always started my 150. Finally softly failed - slow cranking. Spruce shipped a new one to my door within 24 hours of ordering. Looking forward to another great run.

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. In fact when I left the plane stored three times during 3 winters, all I did was bring the battery indoors and then reinstall it after the winter and it was good to go. Great Battery, obviously, Im buying another!

Ive noticed on the reviews batteries dying after 2 years even with tender. Ive had mine for the last 5 years. Never tended battery. Still starts and holds charge. Think maybe battery tending the concord bad idea? I do. Some getting 11 years out of their batteries. Concord please advise users on tending practice.

Last concorde lasted 11 years.... Lets go for another 11!

Had mine in the plane going on 9 years and about 1000 hrs. Died suddenly and reordered a new one. Cant beat 9 years of useful life. Plane was tied outside too and flown every two weeks or so. Never took the battery out in the winter either!

My first choice is always a Concorde battery. As a mechanic I have quit putting Gills in Aircraft.

We exclusively recommend sealed Concorde batteries for my customers. Theyve consistently provided solid performance due to their maintenance-free design and dont cause battery box acid corrosion. We use them in our own aircraft as well.

I have put 3 of these in my aerobatic plane and had every one go 5 years or more. Never have used a battery minder charger and only once had it not start and that was due to alternator regulator issue. Have gone as much as 6 months no charge and still started.

14 yrs old and just now starting to lose voltage. Will I buy another one? No, priced out of my range. Going dry.

5 years and 9 months (69 months) - still going strong. No problems. I had problems with the Gill battery brand (I used up two Gill batteries in two years). Regardless of the great performance of my Concorde battery, it may be time to replace it with another Concorde.

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.

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.

Perfect fit and works great. Just kind of expensive.

Lynn A Verified Purchase

Concorde Battery Sealed RG-25

After nearly 6 years of faithful service in a variety of weather conditions, I recently replaced the Concorde RG25 with another one. Stable and dependable when ossaisionally used with a Battery Minder.

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.

Expected it to last longer.

Ronnie M Verified Purchase

Concorde Battery Sealed RG-25

AGMs are superior Batteries, However My Luck with these is not been good average 2.5 years. I Fly frequently and keep on a battery minder. Trying to deciding if I should try a third and quit the battery Minder?

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.

Had one that lasted 2 years, 10 months. Ordering a new one and hoping for longer. (Stored it inside in the winter) Had two Gills before and they both lasted just around 2 years each.

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.

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.

installed RG 25 Concorde battery into my Cessna 140a January 2020, now having to replace it as no longer holding charge and failed load test. Not impressed with the high cost of these batteries and after 4 years fails load test.

battery is less then 2 years old does not hold charge after couple of weeks product not as good as older battery older batterys from concord much better

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