Should You Stay on GXT4 or Upgrade to GXT5?

If your GXT4 is mid-life (under 7 years old), staying with battery-only replacement is usually right. If the unit is past 7 to 8 years, the lithium-ion Vertiv Liebert GXT5 upgrade path delivers 8 to 10 yr battery life vs 3 to 5 yr SLA, worth modeling on TCO terms for fleets of 10+ units. See our lithium-ion UPS guide.

After replacement, calibrate via the GXT4 front-panel battery test or Vertiv RDU101 IS-UNITY remote management card. Contact us with your GXT4 model number to verify compatibility before ordering.

Vertiv Liebert GXT4 replacement batteries

The Vertiv (formerly Emerson) Liebert GXT4 is an online double-conversion UPS for IT, networking and edge equipment, 500 VA to 3000 VA in this series. Its sealed lead-acid (VRLA) battery modules wear out after about 3 to 5 years; new modules restore full runtime. Use this page to find the right battery for your exact GXT4 model.

For the full range see Liebert / Vertiv UPS batteries.

Battery type and how it scales

The GXT4 line is built on 12 V VRLA blocks (5 Ah or 9 Ah by model); the number of modules scales with the VA rating, and external battery cabinets extend runtime. Vertiv sells the internal pack as a BATKIT: GXT4-5A48BATKIT (4 × 12 V 5 Ah), GXT4-9A48BATKIT (4 × 12 V 9 Ah) and GXT4-9A72BATKIT (6 × 12 V 9 Ah), depending on the model. Match the battery to your exact model number (e.g. GXT4-1000RT120, GXT4-3000RT208) rather than by VA alone.

How to identify the right battery

Find the model number on the rear label or front display. Select the matching battery below, or send us your model number and we'll confirm the correct pack.

Vertiv kit or compatible battery?

Both restore full runtime. Compatible modules match the form factor, voltage and connector of your model's Vertiv kit, with a 1-year UPSPLUSBATTERY warranty.

How long does it last?

3 to 5 years at 20 to 25 °C; heat roughly halves life for every ~8 °C above 25 °C. See when to replace a UPS battery.

How to replace

GXT4 battery trays are hot-swappable, the UPS keeps protecting the load:

  1. Confirm the correct battery (or BATKIT) for your model.
  2. Remove the front bezel and battery tray cover.
  3. Disconnect the battery connector.
  4. Slide the old pack out and the new one in.
  5. Reconnect until secure and run a self-test.

FAQ

What battery does the GXT4 use?

12 V VRLA blocks, 5 Ah or 9 Ah in a string sized to your model (4 or 6 blocks, per Vertiv's BATKIT list). Match by exact model number.

What is a GXT4 BATKIT?

It's Vertiv's name for the pre-assembled internal battery pack for a given GXT4 model (e.g. GXT4-9A48BATKIT). A compatible kit matched on voltage, capacity and connector is the usual replacement.

How often should I replace it?

Every 3 to 5 years; sooner in warm spaces.
