SKU CH-Q3SD-36B3B

Two 8 Ah lead-acid batteries restore runtime for compatible CyberPower UPS units

  • Two 8 Ah lead-acid cells restore full backup capacity
  • Direct fit for CyberPower CP1500PFCLCD PFC Sinewave UPS
  • New sealed units install without tools or configuration
  • Replaces original RB1280X2B pack with identical specifications
  • UPC 649532612116 confirms genuine CyberPower supply

Direct replacement for CP1500PFCLCD

This two-pack of 8 Ah lead-acid batteries is built to match the original specification for the CyberPower Intelligent LCD CP1500PFCLCD and PFC Sinewave Series CP1500PFCLCD units. It restores the UPS to its factory runtime without modification.

Suits owners of the listed CP1500PFCLCD models

Buyers with a different UPS make or model should look elsewhere because the connector layout and voltage curve are specific to these CyberPower units. The pack also does not apply to larger or smaller VA ratings outside the 1500 series.

Two matched cells simplify installation

Supplying both batteries together ensures identical age and capacity, so the UPS charging circuit balances correctly from the first charge cycle. No extra cables, firmware or mounting hardware are included in the package.

Questions about this item

Which UPS models accept the two 8 Ah lead-acid batteries in this kit?

The RB1280X2B kit is made for the CyberPower Intelligent PFC LCD CP1500PFCLCD and the PFC Sinewave Series CP1500PFCLCD UPS units.

Can I mix these new 8 Ah batteries with the original cells still inside my CP1500PFCLCD?

No — the CP1500PFCLCD requires both battery positions to be replaced together so the series string stays balanced.

How do I confirm the replacement batteries are recognised after I install them?

Power on the UPS, let it run a self-test, and verify the LCD shows a full charge icon with no battery-fault warning.
