The OPG series battery adopts tubular plate and Gel electrolyte technology in accordance with DIN 40472 (OPzV) standards. Compared to normal lead-acid batteries, it provides a significantly longer lifespan under deep discharge conditions. These batteries feature strong temperature resistance, excellent charge reception, and fast charging capabilities. Cells can be mounted horizontally or vertically to suit specific requirements.
