*Batteries up to 50 lbs. 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. |

In service (flown) 85 hours over 2 years 3 months. Always kept on a Battery Tender Jr when not in use. Failed after 2 years 3 months. I have $30 lawn mower batteries that last 4 to 5 years under similar duty. |

Poor performance after 11 months, kept it on battery tender, always checked electrolyte level and added distilled water when needed. One cell always seemed to bubble more than others during charging. Now discharges itself to 11 volts in only 2 days if not left on tender, I can recharge, but capacity is about 1/4 compared to when new. Not worth the $$. |

I have always had Gill batteries. Last one was bought 6/5/11, still going fine. The one before that was 9/18/05. Had a few left on master switch issues that might have killed that one after about five years. Think I'll keep trying my luck with Gill till they prove me wrong. |

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.
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.
