  • Weight14
  • Two 12V 9Ah SLA batteries supply reliable backup power
  • Kit matches CyberPower RB1280X2A specifications for direct compatibility

Dual 12 V 9 Ah SLA kit

This two-pack supplies a pair of high-rate-discharge sealed lead-acid batteries rated at 12 volts and 9 ampere-hours each. The kit is built to match the CyberPower RB1280X2A cartridge specification and arrives factory fresh. It is intended for administrators who need a direct drop-in refresh for compatible UPS units.

Replaces depleted UPS cartridges

When the original battery set no longer holds sufficient charge to bridge outages, this kit restores the rated runtime without modifying the enclosure or wiring. The upgrade is worth it when battery self-tests fail or when the UPS reports reduced backup time during utility loss. Installation instructions are included to guide the swap.

Sustained discharge under load

Each cell is engineered for high-rate discharge so the UPS can deliver its full rated power for the duration specified by the UPS manufacturer. Voltage remains stable throughout the discharge curve rather than collapsing after an initial burst. The sealed construction prevents electrolyte leakage during extended operation.
