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 made a mistake ordering this battery. I promised myself years ago never to buy an open cell battery where I need to handle the acid. These kind of batteries should be discontinued. Who in the 20th century needs to fool around with battery acid? Awful. Spruce should only offer closed cell gel batteries! Greetings, great work you Spruce guys.

Battery lasts about 2 years for me, however, I do let it sit in one month intervals between runs. Does the job, Aircraft Spruce was quick & efficient Thank you!

I have had a number of Gill 35 since 1985. No problems. Great shipping packages never a damaged battery. My last Gill lasted eight years. The handle is a nice feature.

This review is not only for the Gill G-35 battery but for several items in the same shipment getting ready for my annual inspection. All the items arrived in good condition, packed very well and quickly processed and shipped like lightning. Thats the main reason I come back to Aircraft Spruce for all my aviation needs.

Good battery, dont get me wrong. I gave it 4 stars only because of the cheesy paper funnel included with the battery acid. Its practically impossible to fill the battery safely with this thing. You WILL spill battery acid, you WILL get it on you , you WILL damage your clothes and you MIGHT injure yourself terribly. Battery acid is scary stuff. What were they thinking??????

Second time I buy. First one lasted 5 years. No complaints. Shipping was quick. Acid and battery are in separate box, so you need to pour in a well ventilated area. Make sure you have a thick paper or card board underneath battery for first charge, it is a bit messy. Neutralize acid overflow with baking soda and clean battery before placing back in plane or you will damage your paint on belly through overflow vents.

I changed over to Concorde this time. Last two Gills did not hold up. From reading the other comments, it appears that it is a hit or miss as to whether you get a good gill battery or a lemon. Prior to the last two, a Gill battery would last 6 to 7 years with out any problem.
