Perfect fit in my 210B, unlike Concorde which required trimming the upper plastic extrusion on top to fit in the battery box. Prompt delivery, excellent packaging.

Great battery but rather pricy.

July 7, 2020

Worked as advertised. Very strong. Just dropped into my M231K. Easier than some car batteries.

I was charged freight on my last order which included a gill 12 volt battery’ In the past years aircraft batteries were always shipped freight prepaid’ Has the policy changed ?.. Also I was to receive your 2020 catalog with free shipping but I did not receive it, Thanks

Battery came charged but instructed to fully charge before use and that was easy enough. Great starting power. No longer nervous if it will have enough juice in it to start on hot days while doing my preflight. Very happy with this battery.

This Gil battery is a preemptive replacement for one I bought from Aircraft Spruce over 3.5 years ago and has given me out standing service over that time.

Do not buy a Concorde, this one is cheaper and is as good. The Concorde G35 I bought at a premium price lasted exactly 8 hours. Concorde Tech Support is a joke. I think like most companies, Concorde, once they were known for a great product let quality fall. I will NEVER buy or suggest to my clients at my FBO ever buy Concorde. I have never had a problem with Gill.
