Questions about this item

What UPS models does the RB1290X4D cartridge fit?

The cartridge is compatible with CyberPower PR1000LCDRTXL2Ua, PR1500LCDRTXL2U, PR2200LCDRTXL2U, PR3000LCDRT2U and PR3000LCDRTXL2U UPS systems.

How is the pre-assembled cartridge installed, and what step do people often miss?

Slide the cartridge into the UPS battery compartment until it seats firmly, then reconnect the internal battery connector — skipping the connector leaves the UPS running on bypass.

When will the four 12V 9AH sealed lead-acid batteries need replacement again?

Expect 3 to 5 years of service; the 18-month warranty covers early failure, and the reusable packaging lets you return the expired pack for recycling.
