I called in my order. I had previously ordered this battery from Wag Aero but had not received information about my order. The sales associate found my information and had the battery shipped out. I received it in a couple of days and am up and flying again.

Great battery. Comes fully charged and ready to go. I have it installed in a Globe Swift GC- 1B, It is lighter and a bit smaller than my previous battery. A reliable, good performer.

CONCORDE SEALED BATTERY RG-35A

Best battery ever. I installed one in a customers Piper August 2010, was kept on a Battery Minder and after 14 years is still passed the capacity test. Same battery in my Cessna 182 passed capacity test for 7 years, but kept on working. Only had 2ea Concord failures in over 20 years.

Replacing RG-35A which I installed on my PA-28 in 2019. I’m hoping to get more than 5yrs out of this one now that I keep it plugged into a Batteryminder with quick connect accessory. Used to get 2-3yrs tops out of the Gill wet batteries so not bad.

good product, timely service

Harry I Verified Purchase

CONCORDE SEALED BATTERY RG-35A

The last RG-35A battery I purchased lasted 13 years. The battery was used to start a Rotax 912S engine (100 hp) during its 13 years of service, as well as to provide power to a transponder and radio when the engine was not running. This was in a motor glider application. I was very please with its performance.

THE LAST BATTERY I HAD OF THIS MODEL WAS ALMOST 40 MONTHS. VERY SATISFIED.

Concorde batteries are excellent and their factory support is top shelf. I ordered this particular RG35A to replace an identical unit that held up well for 7 years. Not too shabby.

This same battery lasted a terrific 63 months. Granted I ran it down a couple of times but also took care of it with the Battery Minder charger for with desulfation circuits calibrated for the Concorde battery. Reliable pair.

Randy S Verified Purchase

CONCORDE SEALED BATTERY RG-35A

Put one in my Archer II back in April of 2015, its just now starting to show a little loss of voltage at idle, 11.6V 5.5 years of service, better than any other batteries Ive used & the longest service life.

I can get over 6 years out of this battery.

Mark D Verified Purchase

CONCORDE SEALED BATTERY RG-35A

Top of the line battery and I will only use a sealed battery any more due to possible acid contamination.

Good quality battery at fair price (for aviation). Hopefully it will last five years like my last one.

Arrived within a two days. Installed it and operates as designed. Quick and efficient service.

Quick service on delivery. Battery is great arrives fully charged.

Came fully charged. Cherokee started right up. Along with the battery tender/charger, Im sure it will last for many years to come.

good value promo service THANK YOU

Excellent and Durable Product for Aircraft...Thank You

In my not so humble opinion the RG series of Concorde batteries are the best available lead-acid General Aviation batteries. A great product at a fair (by aircraft standards) price. And, they are essentially maintenance free which is a blessing considering how hard it is to access many light aircraft batteries that are tucked away in obscure places.

Should last many years

Very very happy with this purchase and even moreover that I ordered this on 9/14 and received it on 9/16. I was so very impressed that Aircraft Spruce is delivering Amazon service... Very...

Great battery that arrived fully charged, in good condition, and very quickly with standard shipping.

Ordered online Friday afternoon, arrived Monday afternoon in good condition.

I installed this battery (Concorde RG-35A) in my Mooney M20C on 2/18/2012. This week (7/25/2020) I started having problems. I attribute the longevity of this battery to a great design and the BatteryMinder which was always connected. I hope I see 8+ years on my next RG-35A. Highly recommended!

The battery that I purchased last year went bad and I replaced it with this one. I have filed a warranty claim to get reimbursed.

Cranks my IO-520 right up, even with 8 ft remote mount. Used to take three attempts to get the current flowing on my last battery. Also, fast delivery in good packaging.

Arrived in perfect condition and was a drop-in replacement for the old battery. I hope this one also lasts almost 5 years.

The battery arrived timely, well packed and appears to be in good condition. Due to the Covid-19 pandemic I cannot leave home to install the new battery in the airplane and use it.

Shipped fast. Item as described. Thanks

Awesome service!!!!

Fine

Great service and free shipping on a battery.

Shipped promptly and was well packaged. Good working Battery.

The Concorde batteries are wonderful. I think the last one I had lasted at least 5 years and one of those years the plane was at another airport where I couldnt recharge it. Aircraft Spruce had the battery to me very quickly.

Works as advertised.

Good

Battery works great and came highly recommended by my A&P.

Quick delivery as always. I got 7 trouble free years from the last Concorde battery - looking forward to the same from this one.

Great Battery. I keep this on the BatteryMinder and fly about 150 hours a year. The last battery started to turn the engine over a little slowly and once refused to after 5 years. I figure after 5 years a battery doesnt owe me anything. Replaced it and It fires up like its eager to go. No acid, no fumes, no trouble.

This was an easy swap for my old Concorde battery. It lasted 5 1/2 years, so I definitely got my money’s worth out of it.

Replace my old Concord after 8 years. Great battery!

Ill never buy a pink one again ! Shipped when promised,very satisfied

I LOVE this battery!!! It cranks my plane right over and continues to impress me!! I’m glad I made the switch to this brand!!!

I noticed the cranking speed is a little slower today when I fired up for a short flight. I was thinking I just replaced that battery. I popped the cover off to see the date I installed it and found out it was in July of 2014. Today is February of 2018. Time does fly.

Reliable and peace of mind knowng with my Concorde Battery that it start my plane everytime

This battery arrived 22hrs after I ordered it. I installed and the airplane turns over amazingly.

I used to have to replace my battery every two years. Switched to Concorde and this last battery lasted 8 years!!!! This truly is the best battery on the market.

My last one lasted 7 years on a maintainer and was still fine when I changed it to a new one. Great battery. Prompt shipping right to the front door, well packaged.

OK so far, just installed new RG-35A. Aircraft cranked right up. My last RG-35A lasted 3 years 2 months. I was a bit disappointed. I use a 2W solar charger when the airplane sits for awhile. I have car batteries that are guaranteed for 5 years and cost a lot less. Why do these aircraft batteries die after 2-3 years.

I installed this in 2012 on my 1968 Mooney M20C Ranger Im just replacing it now after 5 years of flawless service. Im replacing it because I noticed it getting slow and do not want to get caught at night at a small airport with no services. I do carry a portable power pack but never needed it t to jump the plane.

Great battery at a great price

Ive used a competitors brand only once and I quickly learned there is no substitute for the reliability & longevity of the Concorde brand-all with no maintenance!

Customer has installed and used battery and could not be happier. Arrived when it was promised.

My last one lasted 5 years. Beginning to be slow to start my mooney. Aircraft Spruce still the best price and prompt shipping.

The newer line up of sealed batteries have proven to be very solid. Some planes tend to boil acid out sort of no-matter what and the source for corrosion. This battery takes care of that issue. I sell and recommend these batteries over the flooded cells with a very high success rate.

Phenomenal battery. No more battery box required for catching acid. No more fills and spills. I bought this battery in 2007 and its still working just fine at the end of 2016.

Best battery on the market!

On 8.5.08 I installed the RG-35 in our Cessna175 powered by a Franklin 220 hp at with 10.5 to one compression. Today 2.1.16 I am purchasing a new one, not because the battery is bad but it was dropped and broke the case. Before the Concord was installed I could count on replacing the Pink G-35 ever 24 months. This is a great battery.

Good battery. Bit pricey but expected for pmad item

Roland M Verified Purchase

CONCORDE SEALED BATTERY RG-35A

Cost has shot up dramatically. I replaced a 3 year year old a Concord RG35AXC with a RG35A becuase it would not hold a charge. Even with a battery minder, starting power dropped was extremely week, several attempt to turn engine over, starter tested ok

Read numerous reviews of longevity of these. Battery tender and a heat blanket and two years almost to the day, Im looking for a better battery that doesnt feel like Im blowing my money for the equivalent of a cheap battery.

Replaced gill 35 in my c-210. Average three cranks and inadequate amperage to start engine. Needs a booster **hard to find away from home or hanger. Seven months old. Advice *Look elsewhere

Don’t believe the hype, the G-35 I bought will not hold a charge. Total time on battery is 8 hours. I’m a AP, IA and know a piece of junk when I see it.
