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.

I am very happy to say the battery arrived in the time promised, packaged very well and un damaged!!!! Unfortunately I cant say the same for my recent order of a can of Royco 756 oil which arrived damaged and leaking.

Product is well known. Dependable. Easy to prepare and install. The 5 stars, however, are more associated with Aircraft Spruces easy ordering process and quick delivery of the batteries.

Arrived the next day. Great instructions on how to add the acid and charge. All went as planned. My last G25 lasted me 6 and a half hears in my C-172, and Im hoping this one delivers as well.

Q&A

Q: What's the advantage of ordering with acid versus without acid?

The battery requires acid. The only reason to order without the acid would be if you already have electrolyte that you can use to fill the battery.

Q: Does free shipping apply to the version "with acid"?

Yes, this battery will qualify for free ground shipping to the lower 48 USA with or without acid.

Q: Will I need to charge the battery, or can I just install it and go?

Gill recommends that you fill it, charge it, and then use it. If it is absolutely necessary, you can pour the acid in, wait an hour, and use it but it will hurt the longevity of the battery.

Q: Hello, I put the G-25 with acid in my shopping cart and I see it says free shipping and I see in a question, someone asked if this is eligible for free shipping and you said it is, but in my shopping cart the battery is flagged with a Hazardous symbol. Is there a shipping charge for the hazardous material? Thank you.

No, these are not considered hazardous for ground shipping in the USA. These do qualify for free ground shipping and you will not incur an additional hazardous charge if you select the free ground method.

Q: I ordered a Gill g25. My question is what type battery is this considered for charging purposes. I have battery type on my charger as Regular/AGM (Absorbed glass mat) or GEL?

It's a Dry-Charged Lead Acid Battery.

Q: What is th weight of the standard Gill G-25 serviced and charged?

Approx 21 lbs filled.
