Design & Performance
The 8A27 AGM series uses high-density lead-tin alloy plates and an absorbed glass-mat separator system to deliver exceptional cycle life and deep-discharge recovery. Its recombinant gas technology allows for safe, low-pressure venting and zero electrolyte loss. The robust polypropylene case resists corrosion, impact, and temperature extremes—making it a top choice for solar, marine, and mobility systems.
