Discover EV8DA-A 12V 280Ah AGM Traction Battery – High-Performance Dry Cell for Industrial & Renewable Use

Discover EV8DA-A 12V 280Ah AGM Traction Battery – High-Performance Dry Cell for Industrial & Renewable Use

The Discover EV8DA-A 12V 280Ah AGM Traction Battery is engineered for rigorous industrial and renewable energy applications. With its dry cell AGM (Absorbent Glass Mat) construction, this battery is sealed, non-spillable, and maintenance-free, offering the ruggedness of a traction battery without the need for daily service. Built in the 8D footprint, it delivers heavy-duty deep cycle performance, making it ideal for powering forklifts, floor scrubbers, aerial lifts, and other electrically driven equipment. Its design leverages advanced alloy materials and hydro polymer separators to deliver consistent performance under repeated discharge cycles. 

Beyond industrial use, the EV8DA-A is also well-suited for large renewable energy storage systems and off-grid installations. With a broad temperature tolerance (discharge down to –40 °C and storage up to +60 °C), it remains reliable across diverse climates. The battery’s dry cell AGM nature eliminates the risk of leakage, and its AT terminal configuration allows for easy integration into existing 8D battery racks or systems. Its robust design, combined with strong cycle life and deep discharge tolerance, provides a compelling solution for demanding energy storage and motive power applications.
