CONCORDE SEALED BATTERY RG-25XC

Excellent battery, best on the market but itll only last you as long as you use a proper Battery Batteryminder thats purpose made for Concorde batteries. Thats the difference between 2 years and 6 years of use. Better than Gill. XC versions give that added bump in power for cleaner startups.

CONCORDE SEALED BATTERY RG-25XC

The last two of these in my own airplane lasted seven and eight years. I use the charger Concord recommends. I recommend these to any customer needing a battery.

Replaced a 7 year old Concorde RG-25 with this XC model. After 7 years the RG-25 was getting a little weak although it still tested ok. Was lucky to get 3 years out of the pink ones.

These are excellent batteries. I replace them every 5 years out of habit, though I suspect they will last much longer. I have never had a problem starting my engine and have never needed to charge the battery. Completely trouble free.

With the appropriate charger, this model has lasted 4-5 years and eliminated battery box corrosion for me.

Gary M Verified Purchase

CONCORDE SEALED BATTERY RG-25XC

I bought an airplane 17 years ago that had a Concorde battery in it. It lasted around 12 years before I bought another one to replace it and it still works just fine. I just bought a C150 that didnt have a battery so naturally I purchased a Concorde battery for it. Sad the price has gone up so much over the years but it is still worth it.

CONCORDE SEALED BATTERY RG-25XC

Great battery ! The first one lasted almost 5 years. (Guess you can’t expect much more) I only fly about 50 to 70 hrs a year. It has about 20 percent more power to turn my 160 hp. 172. Expensive, but so is a dead battery 300 miles from home. I would purchase again and I did.

Infinitely better than a Gill battery and even better than the RG-25. Well worth the small difference in price over the RG-15.

Great battery, great starting power

Product arrived quickly, fully charged and ready to be installed. Makes a find a replacement for the previous battery.

Excellent service and batteries arrived on time in expected condition. These batteries lasted 6 years and I expect these replacements to perform as well also.

Thanks it was quickly and efficiently delivered

I’ve been using this brand battery in my RV-6A since 2000. I have been averaging 250 hours a year since then and find that my batteries go, on average, 600 to 700 hours. I can tell you that there are many many many engine starts during those hours and this battery is perfect for my needs!

Aircraft Spruce has been my go to place for most parts and supplies. Always good service , great website and easy to navigate.

Expensive, but worth every penny. Charged to capacity, fit and connected right up.

havent had time to use it much but does crank better

Just what I needed,

Used Aircraft Spruce for years! Second time with this battery and the service was speedy & efficient!

the battery came quicker than they said. Very easy to place orders

Great battery, got here on time.

I purchased my last Concorde RG-25XC battery for my RV6 in 2014. I did not have to replace it until November 2020. I flew about 300 hours in that period of time. In order to keep a full charge and to help extend battery life, I connect the battery to a trickle charger when my airplane is in the hangar. Getting 6 years of service out of a battery is outstanding. They arent cheap but I highly recommend Concorde batteries.

great

Very expendsive

Batteries came as ordered in 2 days

Excellent quality. Fast Shipping!

Great Battery, arrived in timely manner. Packaging was badly damaged but battery was well protected and undamaged,

Awesome battery! Well packaged and arrived early.

On time, great product, lasts tewixe as long as any other.

Best price, quick delivery from an instate warehouse, whats not to like?

Rating is based on the set these replaced -- I had that set for 19 years!

The battery I ordered arrived the next day and worked perfectly. What else can one say about a battery!? I was very pleased, as I always have been, with Aircraft Spruce’s products and service.

Order shipped same day and arrived fully charged. Always great service

I asked a few mechanics about the best battery to get and they all said that it would be Concord. The battery fit very nice. thanks.

I purchased the RG-25XC as a replacement battery for my Citabria 7GCBC. The prior battery was also the same item and it was installed in 2/2007. I maintain the charge with a battery tender when the aircraft is inactive for periods. Great product

Great battery replacement. Strong and reliable. Overnight service from Aircraft Spruce is awesome!

Does what is should. Our old battery (exact same model) was 9+ years old, and the starter always had a bit of a lag to it. With this battery, it cranks up faster than Ive heard it in the 2 years Ive been with this club. There was a slight confusion with overnite shipping, where I was quoted $104, but the system tried to charge $197, but cust svc got it straightened out once I notified them.

Pitts. NX 1410

Very strong battery and it cranks and starts my O360 Lycoming with a few turns of the prop.

The previous Concorde RG-25XC battery had given me almost 6 years of service, and was still starting the engine reliably. I thought it best to install a new battery of the same model, as the starter was turning a little slower on cold mornings.

Bench tested at 13.0 volts out of the box. No top off charge required at install. I dont know how much, if any, better the XC version is, but its cranking power is impressive. My old RG-25 was still working, but was 4 1/2 years old, starting to get weak and nearly left me stranded so I just replaced it. One thing I noticed immediately was the engine fires better and starts quicker with the higher crank rotation speed so thats nice. This is installed in a C-172L model with an O-320-E2D.

Excelent battery

Excellent battery arrived 2 days earlier than originally promised.

Aircraft Spruce is my go-to for most things airplane. Always buy my batteries from them.

I ordered the Concorde RG 25 XC battery, and had a cell go bad, contacted Aircraft Spruce service dept and the problem was resolved quickly and had a new battery on the way. Excellent service..

Delivery was close to instantaneous! Thanks!

I have been happy with the performance of the RG-25XC batteries. My previous one lasted 8 years before it was noticeable slower turning the starter. Even then, it still had more than the rated ampere hours.

Great batteries. Worked great in the Cessna 150. Super fast delivery. Out of the box and straight into the plane.

Our experience with the Concorde RG-25XC batteries has been excellent. Highly recommend this battery if you have a 12volt aircraft. We have a C310 so we use 2 wired together for the 24volt requirement. No complaints.

Worked great, fast shipping

Great product, Arrive on schedule! Perfect!

I installed this battery in our Cessna 172 as a replacement for a 4 year old Gill battery. Perfect fit, service free. I expect many years of trouble free use.

Ordering, shipping, and receiving happened quickly. I did not have to wait long before the new battery was installed and I was flying again.

Delivered fast, works great

Good battery! My mechanic said I should have checked out Gill brand due to price but this was the one I bought. So check out reviews on both and make an educated decision. But as for this battery it started my overhauled o320 up like a dream. But I also had new light weight skytec starter. But from what mechanic said sealed battery is the way to go. Should not have any acid overflow mess to deal with in future. Clean out battery case good with baking soda as your mechanic will suggest. Also no initial charging or pouring water to deal with. God bless! You do need wrench or socket to tighten bolts to attach battery cables. Keep size of wrench in mind. You might want to add this to your planes tool kit in case it loosens up on long trip.

excellent, perfect replacement!

Excellent battery. I really like the extra capacity and cranking power as the battery in my 150HP conversion Cessna 150 is located aft of the baggage compartment. Being sealed means not having to worry as much about battery box corrosion. These batteries have provided very reliable service for many years.

My last RG-25XC lasted 7 years. I just ordered another one to replace it. When I was using a Gill Battery I was only getting 2 years out of them. Plus with this battery I had absolutely no corrosion issues.

Good battery. My last one lasted 4 years.

Concorde batteries are hands down the best aviation battery on the market. I went through 3 Gil batteries before I purchased a Concorde.

Just replaced the old one with a new one in a Citabria 7GCAA. The old one only lasted 10 years and 10 months.

Ordered for a fellow friend and pilot while he was away at work and he was greatly impressed that we received it the next day and dropped it in and the plane started right up!! Thanks a bunch.

I just replaced an RG-25 battery that has been in service for 6 years with an RG-25XC and this battery is worth the money difference between the two batteries. I highly recommend a Concorde battery as a replacement to any other. Its maintenance free with great cranking power.

Been on the aircraft 18 months and so far so good. This is my first concord. Previously used Gill and they became junk. Last gill held for 12 months and one before that was only 18 months and prior to that 24 months. Hopefully the concord will continue to outlast the Gill. It also has better cranking power from what I can tell, even after 18 months its better than a new Gill.

This battery came from the factory in my plane. During the 4th annual the mechanics helper pried off the caps and announced there was NO WATER in the battery he had just ruined. . The replacement battery worked well but got tired after 10 years so it was replaced. Now with 5 years on my third 25XC I feel it has earned 5 stars

As usual, A/C Spruce did an outstanding job at getting the battery from their place to mine ASAP. As far as this battery is concerned, I cant say for sure, but the one it replaced was the same model and it cranked my Lycoming for 10 years. Cant complain about that.

Great battery. Still going strong after several years.

Very happy with this battery having the strongest reputation among competitors with higher start power! The last one removed had been in use for 9yrs!

5 stars even with the high price tag.

What an upgrade from the two Gill batteries in my 58P Baron! The Gills kept going south with bad cells and never seemed to hold a decent charge. The Concorde sealed batteries are like getting a power boost. Even in winter. I have the same battery in my Cessna 140 (just one, of course), and its been happy sitting for long periods for many years now. Never going back to Gill!!

Great batteries - long lasting and dependable!

CB-25XC just died after 11+ years. about 500 hours. NO complaints, ordering another. In hanger, Houston, Texas

This battery is over ten years old and has spent every day outdoors. I have never had a charger on it and it has sat for up to three months between fall and winter. It is not installed forward of the firewall and I believe this has helped with it's longevity because heat if tuff on batteries. Still turning the Skytec starter on a 160 Lyc just fine.

Just removed 2 of these after 12 years. Still working fine, just thought it was about time...

Approaching 7 years and still strong. If I were flying IFR it would need a capacity test. I hangar and don't let it get drained, which is easy, considering how slowly the AGM's loose charge.

The only issue with these batteries is rather than declining in performance over time, they quit taking a charge quite suddenly.

I received order promptly. This replaceda similar battery that was in plane around 10 years.

Quick delivery, proper product, bit pricey

This Concorde does what its supposed to do just too expensive. Delivery and packaging went well.

I have never had a problem with Aircraft Spruce even though we are in Hong Kong. Fast response to orders and on time delivery. Thanks.

Order process went well, fast delivery. The only negative comment I have is the life of the sealed battery (third RG25XC) seem a little short. 2 1/2 years on the average with normal use, 2 to 4 starts a week. Mounting , cables, starter, alternator new or rebuilt and charging system has been checked. ???

This is my second sealed Concorde 12v battery for my 172. First lasted about 5 years, not as long as the old serviceable battery. Don’t let the Concorde get drained. Keep it charged and it will likely last a long time. I don’t think they are as tolerant of deep discharge. Since I let my first one get weak, it never really recovered.

Ive been using Concorde batteries for the 13 years Ive been flying my RV-8. I especially like XC for its extra cranking power. Dont change a good thing.

This is the second set of Concorde batteries I have purchased, used as a set of two 12v batteries in series for a 24v airplane that flies once every 10 days or so on average. The last set lasted about 4 years before a slow start lead to a failed load test, prompting replacement. The batteries seem like similar quality, design and longevity as a premium car battery, but at twice the price (hence only three stars on the rating).

I just bought this battery to replace the same RG-25XC that was only three years old when it wouldnt turn the starter. That battery subsequently failed a capacity test before and after a conditioning charge. This battery was maintained using a Concorde-specific Battery Minder and was never fully discharged. Concorde usually makes the best aircraft batteries but my last experience was disappointing. Im hoping the replacement fares better.

Have used a series of these batteries in my RV6. The last one only lasted 2 years, instead of the 3-5 of previous units, the reason for only 3 stars on this review. The battery performs well on my 0-320, but the cost keeps going up, making me look into newer technologies. But overall, a good battery.

Good while it lasted, but that was only for 25 months. I used a Concord vs a Gill this last time as my last Gill only lasted 18 months. Well, for the price, I think Ill switch back to Gill and just plan on replacing every 18 months.

Battery quit without any warning. Luckily, I had just arrived at my home airport...had to be towed to my hangar. Battery lasted 3 yrs. and 1 month. It was always in the hangar and never exposed to any harsh elements. This battery is no better than the standard Gill 25 battery--original equipment.

Always thought Concord had the one any only battery and still consider it the only one. But last one, Purchased 3/18, actually started leaking and was failing. Past warranty of course but very surpirsed. The top of the battery was snowing leaking around the seams! Still replaced with the new one but not nearly as confident as in the past.

Started to fail after 18 months, completely unusable at 24 months. This is extremely disappointing. Simply would no longer take a charge.

Started off strong. Battery failed in just 14 months. We actually though it was the starter solenoid so we replaced that. Well that wasnt the problem so we pulled the battery and had a capacity test done on it. It Failed after only 204 hours of use. This was in a hangared 172M that was obviously flown often so the battery never got low until it failed completely. Which by the way it still has over 12.4 volts in it, just not the cranking amps.

Failed without warning away from home after 3 years 9 months. Internal cell short resulting in a 3 volt battery. Kept the battery on a trickle charger. Cold temperatures during the trip may have been a factor.

These batteries used to be built better. Last one only lasted 11 months. I wish they had a better built lithium ion or other battery made.
