Batteries

 

 

KCR Lead-Calcium / KAR Lead-Antimony

For switchgear and control applications
Capacities from 180 to 825 Ampere-hours


 
Features and Benefits
  • 20-year environmental and seismic qualification (calcium)
  • Flame-retardant covers enhance battery plant safety
  • Terminals accessible for measurement of individual cell voltages
  • Transparent container allows visual inspection of plates
  • Low-evaporation, flame-arrester vent
  • Electrical testing to 100 percent capacity assures performance of every battery
  • Two-point, top-suspended positive plates permit free growth without pressure on jar and cover
  • Vacuum-assisted, bottom-pour, positive-grid casting assures plate quality and long life
  • Soft rubber post seal minimizes stress on post
