AlphaCell HR

VRLA Battery for High Rate UPS Standby Power Applications
  • Product Line: Batteries
AlphaCell HR
  • Front access threaded copper alloy inserts for reduced maintenance and increased safety
  • Front terminal design maximizes energy density, with direct connect (extrusion fusion) weld technology
  • Reduced headspace creates higher energy density in cabinet or rack applications
  • Removable handles for ease of installation
  • Thermally welded case-to-cover bond ensures a leak-proof seal
  • Description

    The AlphaCell HR valve regulated lead acid battery is designed for UPS standby power applications. This model features Absorbent Glass Mat (AGM) technology for efficient gas recombination of up to 99% as well as flame-arresting one-way
    pressure-relief vent for safety and long life.
    • Specifications
      Operating temperature range with temperature compensation Discharge: -40°F (-40°C) to +160°F (71°C)
      Charge: -10°F (-23°C) to +140°F (60°C)
      Nominal operating temperature range +74°F (23°C) to +80°F (27°C)
      Recommended maximum charging current limit C/5 amperes @ 20 Hr rate
      Float charging voltage 13.5 to 13.8 Vdc average per 12V unit @ 77°F (25°C)
      Maximum AC ripple (charger) 0.5% RMS or 1.5% P-P of float charge voltage recommended for best results.
      Max voltage allowed = 1.4% RMS (4% P-P) Max current allowed = C/20
      Self discharge Battery can be stored up to 6 months at 77°F (25°C) before a freshening charge
      is required. Batteries stored at temperatures greater than 77°F (25°C) will require
      recharge sooner than batteries stored at lower temperatures.
      Equalize charge and cycle service voltage 14.40 to 14.80 Vdc average per 12V unit @ 77°F (25°C)
      Terminal: Inserted - inter-unit connector provided Threaded copper alloy insert terminal to accept 1/4-20 UNC bolt
      Terminal hardware initial torque 110 in.-lbs. (12.4 N-m)

      * Per IEEE 1188-2005, Internal ohmic values are useful as a trending tool. To use these readings effectively, accurate baseline readings should be taken after about six months of battery operation. Internal ohmic readings taken without the benefit of baseline data may be difficult to interpret and of limited value. Values provided are for reference only.
