HPE Tower G5

Batteries for HPE Tower G5 UPS

Why replace the batteries?

• A sealed lead-acid (AGM / VRLA) UPS battery gradually loses capacity, especially in a warm room: its real service life is generally 3 to 5 years.
• Worn batteries greatly reduce runtime, trigger the « battery » alarm and can make the UPS shut down at the very first power cut, exactly when you need it.
• Replacing the batteries restores your UPS's original protection for a fraction of the price of a new UPS.

How to find the right kit?

• Note the HP part number of your UPS on the rating label (on the back or underneath): for example « Q1F52A », « J2R04A », « AF468A » or, for a Compaq, « 242688-002 ». The model name (T1500 G5, R/T3000 G4…) is also on the front panel.
• You can also note the HP spare battery number printed on the battery pack (for example « 796777-001 »): it appears in the name of our kits.
• Compare it with the table below: each kit includes all the batteries of the UPS, in the same format and with the same terminals.
• If in doubt, open the battery compartment and note the number of batteries, their voltage and capacity (for example 12 V 9 Ah), or send us a photo of the UPS and its batteries: we will tell you the right kit.

Replacement tips

• Always replace all the batteries at the same time: a new battery combined with worn ones wears out very quickly.
• Switch off and unplug the UPS before working on it (except hot-swap models, according to the manual).
• Reuse the original cables, links and connectors and respect the polarity (red = +, black = −).
• Let the UPS fully recharge (about 8 hours) before relying on the runtime, then run a battery test.
• Used batteries must be taken to a collection point: they are recycled.
