Batteries

   

4LCY Lead-Calcium / 4LY Lead-Antimony
 For telecommunications applications
Capacities from 290 to 660 Ampere-hours

FEATURES AND BENEFITS
 

  • Four-cell design offers reduced length for optimum space utilization
    (shorter racks)
  • Fewer bolted connectors per battery string reduce installation and maintenance costs
  • Flame-retardant covers enhance battery plant safety
  • Suspended positive plate permits free growth without pressure on jar and cover
  • Snap-on, intercell-connector insulating covers
  • Terminals accessible for measurement of individual cell voltages
  • Vacuum-assisted, bottom-pour, positive-grid casting assures plate quality and long life
  • Soft rubber post seal minimizes stress on post
