The Vertiv Liebert GXT5 is a double-conversion (online) rack/tower UPS used to protect servers, network gear, and other critical loads. Like every UPS in this class, it stores its backup energy in sealed lead-acid (VRLA) batteries that wear out and need periodic replacement. This collection brings together the compatible replacement batteries and cartridge kits for the GXT5 line so you can match the correct part to your specific unit.

What type of battery does the GXT5 use?

GXT5 models other than the lithium-ion GXT5LI use sealed, valve-regulated lead-acid (VRLA / SLA) cells. Individual cells are 12V, and the UPS connects several of them in series to reach the system DC voltage your model needs, which is why GXT5 cartridge kits are sold for specific system voltages (Vertiv lists GXT5-36VBATKIT, GXT5-48VBATKIT, GXT5-72VBATKIT, GXT5-144VBATKIT, GXT5-192VBATKIT and GXT5-288VBATKIT, plus GXT5-9A48BATKIT / GXT5-9A72BATKIT) rather than a single universal pack. Because capacity (Ah) and the number of cells differ from model to model, there is no single voltage or amp-hour figure that fits the entire family. The exact specification depends on your UPS or cartridge model. Each product page in this collection lists the voltage and amp-hour rating for that specific item.

How do I find the right GXT5 battery kit?

The reliable way to order is to match by exact model number, not by appearance. Check the nameplate label on your UPS, or the part number printed on your existing battery cartridge, and match it to the "compatible models" list shown on each product in this collection. Cartridge/kit part numbers (such as GXT5-72VBATKIT or GXT5-144VBATKIT) and the UPS model numbers they serve are both listed so you can confirm fitment before you buy. When in doubt, confirm by the exact model and review the specifications shown in the product grid.

Should I buy the Vertiv kit or a compatible battery?

Both restore runtime when matched to your model. You have two options when replacing GXT5 batteries: a kit sold under the manufacturer's brand, or a compatible cartridge matched on voltage, capacity, terminals and connectors. Manufacturer kits carry the manufacturer's branding and warranty. The right choice depends on your budget, warranty requirements, and internal policies.

How long does a GXT5 battery last?

VRLA UPS batteries typically last about 3 to 5 years under normal conditions. Heat is the single biggest factor that shortens that life: as a rule of thumb, every roughly 8°C (about 15°F) of sustained temperature above 25°C (77°F) can cut usable battery life roughly in half. Keeping the UPS in a cool, ventilated location and replacing batteries on schedule helps avoid an unexpected loss of protection.

Can I replace a GXT5 battery myself?

Yes. Vertiv describes the battery of the 500 to 3000 VA, 120 V GXT5 models as hot-swappable and user-replaceable, and the batteries in the 5 to 10 kVA external battery cabinets as user-replaceable. General steps for replacing a UPS battery cartridge:

1. Order the correct cartridge for your exact model.
2. Note the orientation and connections of the existing cartridge before removing anything.
3. Release the front bezel / battery cover and slide the old cartridge out.
4. Insert the new cartridge fully until the connector seats.
5. Recharge fully (typically several hours) before relying on backup runtime, and dispose of or recycle the old batteries responsibly.

Hot-swap note: Hot-swapping (replacing batteries while the UPS keeps running) is supported only on units designed for it: rack/tower online UPS such as the GXT5 and hot-swap-capable Smart-UPS style models. Desktop and Back-UPS style units are not hot-swappable: power them down before changing the battery. If you are unsure whether your unit supports hot-swap, power it down to be safe.

Frequently asked questions

How do I know which battery my GXT5 needs? Match the model number on your UPS nameplate or existing cartridge to the compatible-models list on each product page. The product grid also shows the voltage and amp-hours for each item.

Are these batteries Vertiv parts? No. The batteries we sell are compatible replacements, matched on voltage, capacity, terminals and connectors; each product page lists its voltage and capacity.

How long do GXT5 batteries last? Typically 3 to 5 years, less in hot environments.

Can I replace the battery without shutting down the UPS? Yes on the 500 to 3000 VA, 120 V GXT5 models, which Vertiv describes as hot-swappable; for larger models, follow Vertiv's manual. Always follow the steps above and verify your specific configuration.

Where does the battery ship from? Orders ship from Canada.
