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.

The Gill 7025-20 is a 12 volt aircraft battery, sealed with no electrolyte required. Suitable for GA single and Twin Engined aircraft.

Replaces G-25S

Gill Valve-Regulated Lead-Acid (VRLA) battery technology contains all electrolyte absorbed in glass-mat separators, with no free electrolyte and is sometimes referred to as a sealed battery. The electrochemical reactions in a VRLA battery are the same as a standard flooded-cell battery, except for the Oxygen-Hydrogen gas recombination mechanism that is predominant in VRLA batteries.
