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.

Review is based on the ordering and shipping. Shipped and received very quickly! Hopefully with the price of an Airplane battery, it will last for a good five years or more. I do have and plan to keep mine on a battery tender.

I have used both Gill and Concord wet cell batteries since 1981. Plane is always hangared in Phoenix (hot!). No problems, and I usually get at least 5 years on each. I do use a battery tender. I just cant see spending even more money on a non-serviceable sealed battery that may not even last longer than a wet-cell. The batteries already cost way too much (as everything airplane!) so I plan to stick with this type. At half the price, they would be a good deal.

After only a year, I could tell the battery was losing its capacity. Starts were getting more and more sluggish, especially if it sat for more than a week. Very expensive considering the short life. Not happy at all. Next battery will be a Concord.

We also use a Battery Tender (BT). The previous battery lasted 5+ years without a Battery Tender. Our A&P tells us the quality of the recycled lead is relatively low when compared to prior years. So we now use the BT with no issues to report. The battery is used in the heat of Florida in a hangered aircraft.

Excellent battery for C152. Service was excellent - battery arrived in 4 days.

We still have not completely killed it but its time not to push our luck. The battery has given us 10 years of service. We do use a Gill battery charger and are in a hangar in PA. Also our IA does a deep service on it every annual. Cant find an issue with this battery.

I got a solid 5 years out of this battery with no tender on my Cirrus SR22. I do fly about 150 hours a year so the Gill gets charged regularly. My bird is hangered in northern Minnesota (unheated) in some of the harshest conditions on the planet. Im buying another Gill as I write.

My G-243 has started my C-172 for the past 7.5 years. I keep the battery on a Battery Tender.

Q: When ordering the Gill G-243, we have an option for with acid or without acid. I do not have any acid, so do i need to order the battery with acid?

Yes, if you do not already have the electrolyte, we recommend buying the "With Acid" version since it will be shipped with the required amount of acid to use the battery.

Q: I need to replace my old g243s battery. I only see a g243 in your ad. What is the difference?

The difference between the G-243S and the G-243 is that the 243S was a sealed battery and the 243 is a wet battery that you will need to pour the electrolyte into. The G-243S was replaced with the Gill 7243-14 LT battery. See our Part # 11-13534 to order this battery.

Q: If I buy the Gill G-243 battery without acid, will it be shipped overseas as dangerous goods?

No, the battery without the acid is not considered dangerous goods for shipping.
