Replacement battery for CyberPower UPS units

This 12 V sealed lead-acid cell replaces the original RB1290 battery in compatible CyberPower UPS models including the CP1000AVRLCD, CP1000PFCLCD and CP1000PFCLCDTAA. It restores backup power capacity when the factory cell reaches end of life. Installation follows the UPS manufacturer's standard battery-replacement procedure.

Lead-acid chemistry limits

Sealed lead-acid cells lose capacity over time and with repeated deep discharges, so runtime will gradually decrease even with a fresh replacement. The chemistry also requires periodic recharging during long storage to prevent permanent sulphation. Buyers who need longer runtime than a single 12 V cell provides or who want lithium-based cycle life should consider a higher-capacity UPS instead.

Highlights

  • Direct replacement for CyberPower UPS models
  • 12 V lead-acid cell restores backup runtime
  • OEM RB1290 compatibility ensures correct fit
  • New condition guarantees full service life
