What this kit replaces

The Vertiv GXT4-9A48BATKIT is a new, hot-swappable lead-acid battery kit built for internal use in Liebert GXT3 and GXT4 rack-tower UPS units. It restores runtime for 120V and 230V systems rated at 1.5 to 2 kVA without powering down the load.

Voltage and capacity match

The kit delivers 48V at 9 Ah, the exact electrical specification required by the compatible UPS models. Installing a kit with a different voltage or amp-hour rating would prevent the UPS from charging or discharging correctly.

Supported UPS models and limits

The kit fits GXT3-1500RT, GXT3-2000RT, GXT4-1500RT and GXT4-2000RT units. It does not support larger kVA ratings, different form factors, or UPS families outside the listed GXT3 and GXT4 rack-tower lines.

Questions about this item

How much runtime does the 9 Ah 48 V rating give my GXT4-1500RT under load?

The 9 Ah 48 V kit restores the original capacity of the GXT4-1500RT and GXT4-2000RT, delivering the same backup minutes you had when the UPS was new.

Does the hot-swap feature work on both 120 V and 230 V GXT3 and GXT4 rack-tower models?

Yes, the battery kit is designed for hot-swap replacement in GXT3-1500RT, GXT3-2000RT, GXT4-1500RT and GXT4-2000RT units running on either 120 V or 230 V input.

Will this kit fit inside my 2U rack-tower chassis without rails or brackets?

The kit is built as a direct internal replacement for the GXT3 and GXT4 1.5–2 kVA rack-tower UPS, so it slides into the existing battery compartment without extra mounting hardware.
