GFM series is the general purpose battery with 18 years design life in float service . With heavy duty grids , thicker plates , special additives and up-dated AGM valve regulated technology , the GFM series battery provides consistent performance and long service life. The new grid design effectively reduces the internal resistance , which provides higher specific energy density and excellent high rate discharge characteristics.
It is suitable for communication back-up power and UPS/EPS applications.
