Caterpillar VRLA Battery Specifications




Valve-Regulated Lead Acid Battery

  • Maintenance Free and low maintenance… accessible or sealed.
  • Deep Cycle and Valve-Regulated (VRLA) Gelled or Absorbed Glass Mat (AGM) batteries.
  • Hefty full frame grids, no sharp edges. Optimum acid/paste combination provides better charge acceptance after deep discharge.
  • Silver (Ag) Calcium Grids for high temperature automotive usage.
  • Commercial batteries have Anchor Lock elements for vibration resistance.
  • Flame Arrestor Safety Vents to direct corrosive gases away from the battery and hold-downs.



Cat Batteries

Gelled (GEL) Electrolyte, Marine/Recreational, Deep Cycle Capability

  • Starting/Deep Cycle Marine or Recreational Use Battery.
  • Could be used for Gen-Sets or UPS type applications requiring a sealed battery.
  • VRLA batteries use recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead acid battery.
  • They are non-spillable, never need watering and should never be opened.

Notes:
MF-AGM/VRLA = Maintenance Free-Absorbed Glass Mat (AGM) Battery. Battery has Flame Arrestor and is low-pressure self sealing
Housed in flame-retardant polypropylene (rated 28 LOI) 12-Volt Monoblocks.
(A) = Battery is 2.5 in. (63.5 mm) taller and .57 in (13mm) longer than standard Group 31.
(H) = Battery has handles.
Sealed Valve-Regulated Lead Acid (VRLA) with electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers.
Preferred for high-rate performance in uninterruptible power supply (UPS) or standby applications.
VPC = Volts per Cell.
WPC = Watts per Cell. Ratings conform to IEEE-485 Standards.
