GFM series is a general-purpose battery designed for a 20-year lifespan in float service. Featuring heavy-duty grids, thicker plates, special additives, and advanced AGM valve-regulated technology, the GFM series ensures consistent performance and long service life. The new grid design effectively reduces internal resistance, offering higher specific energy density and excellent high-rate discharge characteristics. This makes it ideal for communications backup power and EPS/UPS applications.
