Battery configuration

This kit contains four sealed lead-acid cells rated at 12 V and 7 Ah each, designed as a drop-in replacement cartridge for compatible CyberPower UPS units. The pack restores runtime when the original batteries have weakened or failed completely. Installation uses the existing connections inside the UPS and requires no additional fluid or maintenance. Reusable packaging is included for returning the spent cells to a recycling centre.

UPS compatibility

The cartridge fits the PR750LCDRTXL2U, PR1000LCDRT2U, PR1000LCDRTXL2U, PR1000LCDRTXL2UTAA, PR1500LCDRT2U, PR1500LCDRT2UN, PR1500LCDRTXL2U and BP48V45ART2U models listed by the manufacturer. Owners of other CyberPower UPS systems or units from different brands will need a different battery kit. Buyers who require a higher amp-hour rating or a different voltage arrangement should look for an alternative pack.

Pack weight

The complete kit weighs 51.15 lb, so the installer must be able to handle that mass when sliding the cartridge into the rack-mount chassis. Lighter or heavier replacement packs are not covered by this part number. Confirm the weight allowance of your rack and lifting equipment before ordering.

Questions about this item

Which CyberPower UPS models accept the four 12 V 7 Ah batteries in this kit?

The RB1270X4F fits the PR750LCDRTXL2U, PR1000LCDRT2U, PR1000LCDRTXL2U, PR1000LCDRTXL2UTAA, PR1500LCDRT2U, PR1500LCDRT2UN, PR1500LCDRTXL2U and the BP48V45ART2U extended battery pack.

Can I keep my existing BP48V45ART2U battery pack and add this cartridge to it?

The BP48V45ART2U is listed as a compatible UPS system, so the cartridge replaces the internal batteries of that pack rather than connecting alongside it.

How do I verify the kit is working after I install the four batteries?

Power on the UPS, confirm the LCD shows a full charge and normal output voltage, then run a self-test from the front panel to validate runtime.
