Compatible Battery Kit for Liebert UD900 UPS

This replacement battery kit is designed for the Liebert UpStation 900 UPS. It contains four 6V12A sealed lead-acid batteries that match the original specifications. The kit suits administrators who need to restore backup power to an existing UD900 unit. Buyers requiring a different voltage or capacity should verify their UPS model before ordering.

Sustained Discharge Performance

The batteries are rated for high-rate discharge, delivering consistent current during extended power interruptions. Each 12 Ah cell maintains voltage stability throughout the discharge curve rather than dropping off after a short burst. This behaviour supports server loads that demand steady runtime until generators start or graceful shutdown completes. Systems needing longer autonomy will require additional battery strings.

Thermal and Power Characteristics

Sealed lead-acid chemistry operates without active cooling, so the kit adds no fan noise to the rack environment. Normal float charging draws minimal power and the batteries are rated for a 20 °C ambient operating temperature. Heat output remains low during standby and moderate during discharge, allowing installation in standard UPS enclosures without extra ventilation.

Questions about this item

How much heat does the 900 kit generate during continuous operation?

The sealed lead-acid cells produce minimal heat under normal float charge; keep the UPS vents clear and ambient temperature moderate for best life.

What existing hardware is required to install the four 6V12A cells?

You need a compatible Liebert UD900 UPS cabinet and basic hand tools; the kit includes illustrated replacement instructions.

Will the 12 Ah pack work alongside the original charger in an older UD900 unit?

Yes, the 6 V 12 Ah batteries match the factory voltage and capacity, so the existing charger manages them without modification.
