Overview

The Gill Electric Company was founded by Mr. Lawrence Gill in 1920, in Redlands, California, where the factory remains today. At that time, Gill Electric manufactured lead-acid batteries for the automotive industry. During the war years, Gill manufactured batteries for military ground vehicles and aircraft; some of these batteries are still in production today. Gill Electric improved the drycharged process which provides a fresh charged product when the electrolyte is added. Gill has become the OEM "original equipment battery" for Raytheon, Cessna, LearJet, Mooney, Piper, Ayres, Airtractor, Maule, Scheizer and others in the aviation industry and Gill continues to be the industry's choice for quality battery products.

This is the battery I needed and it was the best price I could find. No hassle whatsoever ordering or receiving it. Enough of this review writing, Im going flying.

I have had my Mooney 252TSE for 13 years and have gone through only 2 batteries (G-242) in that time. After 13 years I am now buying a third one. The previous one I bought and installed 4/2012. Thatâs 6 1/2 years of regular usage. In the past year I havenât flown much and had to charge it a couple of times before a flight but overall Iâm happy with the performance. I wish they werenât so expensive though. Kind of crazy beings a car battery is 1/5 the cost.

In our 185 and lasted 6 or 7 years. Not happy about the huge pricetag, but other companies charge the same

Ive been getting 8 years on these batteries! Ive owned my Cessna 185F for 25 years and just now need my third battery! The tech folks at Gill tell me I need to upgrade to the 7242-14 which is sealed and more reserve life. That is nice, but its $150 more, so Im torn which way to go this time. I suspect those experiencing short battery lives arent taking care when they do their initial charge to bring them up very slowly. As advised by a Gill engineer, youll want to initial charge at only 2AMPS! This instant gratification mentality is killing their investment. If youre leaving it up to the mechanic, remember, he makes more money by doing a rush job. Also, clean your battery top before servicing, and then only service with distilled water & do your charge top off out side of the airplane!

OK product. Not durable when compared to other vehicle batteries.

Shipping was fast, and it fits like it was built for the box. I know, the box was built for it, but Im reviewing the battery! Easy to add the acid, only a couple spills.started the 152 right up, no problems there. I am hoping this battery will last longer than my last Gill. The review lost a star for historically short life on this product.

Our experience has been much better than previous reviewers. We have run 242s in Cessna 185s and get usually better than 5 years of service. I just pulled one out with over 6 years on it because the ground post became loose, but we definitely got our money out of it.

The purchase was well executed. The warranty process is flawed. Now the return department is demanding hard copies of all warranty documents when they already have everything scanned and emailed. this is an unnecessary delay in processing a warranty claim.
