Hot-swap 9 Ah battery kit

The Vertiv GXT4-9A72BATKIT is a hot-swappable lead-acid battery kit designed for internal installation in compatible Liebert UPS systems. It contains six 9 Ah cells configured to deliver 72 V and is rated as spill-proof for safe handling. The kit weighs 25 and is supplied new for immediate deployment.

Replaces GXT3 and GXT4 3000RT batteries

This kit directly replaces the internal battery sets in Liebert GXT3-3000RT and GXT4-3000RT UPS units, including the 120 V, 208 V and 230 V models. The hot-swap design allows replacement without powering down connected equipment, so the upgrade is worth it when runtime has degraded or scheduled maintenance is due.

72 V 9 Ah capacity for 3000RT runtime

The six-cell arrangement provides 72 V at 9 Ah to support the rated load of the 3000RT series during outages. It comfortably handles the intended backup duration for these UPS models and runs out when the cells reach end-of-life or when the connected load exceeds the UPS rating.

Questions about this item

What are the voltage and capacity ratings of each battery module in this kit?

Each of the six internal modules delivers 12 V and 9 Ah, combining to a 72 V string for the compatible UPS units.

How do I hot-swap the battery modules without powering down the UPS?

The kit is designed for hot-swap replacement; remove the front bezel, slide out each spent module, insert the new ones in the same orientation, and secure the bezel — skipping the bezel latch is the step most often missed.

When should I plan to replace these lead-acid modules again?

Typical service life is three to five years; schedule replacement when the UPS reports reduced runtime or the battery status indicator shows degradation.
