  • Utillizes Thin Plate Pure Lead (TPPL) technology. Thin positive grids are produced from high purity lead from a unique manufacturing process to maximize corrosion resistance and service life while maximizing energy density
  • Separators are Absorbent Glass Mat (AGM) made from high purity, superior quality fibers. The electrolyte is absorbed within the AGM, preventing acid spills in case of accidental damage
  • Electrolyte is produced from extremely high purity acid to reduce self discharge rate and float currents
  • Container and cover in flame retardant UL94-V0 material, highly resistant to shock and vibration
  • Top terminal batteries use a copper alloy insert
  • Self-regulating one way pressure relief valves prevent ingress of atmospheric oxygen


  • Designed for operation in traditional float applications and cyclic/hybrid applications
  • PowerSafe® SBS® batteries are designed for use in cabinets or on racks, close to the point of use. A separate battery room is not required.
  • SBS EON Technology® models can be mounted in any orientation except inverted. In cyclic/hybrid applications, EnerSys® recommends to install SBS 320 - 900 cells in horizontal orientation.
  • Up to two year shelf life
