Question about Powerware 5110 UPS System
Here is the test I made: - Unplug batteries - Power on the UPS - Replug the batteries, then we can hear a small "click" from the relay probably to start charging the battery. - Unplug the batteries again, the relay does not move. - When I measure from the batteries connectors, I have 22.5V on both the Battery side, and the UPS side (Disconnected of course). It seems that the charger is only sending 22.5V while we would expect 25V (2x12V batteries).

1st, the 9120 is a 700, 1000, 1500, 2000, 3000, 5000 or 6000 Va
if it is a 6000 Va that voltage sounds ok, and the ups as no problem, each battery will be around 12,75 Volts, it will be higher and the charging circle ends.

After you replaced the batteries did you perform a manual battery test?
If not do so.

SOURCE: Hello, my Powerware 3105 beeps
Your problem is showing up under the Powerware 9305 (a very large UPS) but your comments are about the 3105. It sounds like your battery is dead. If your UPS is over 3-5 years old, that's most likely the case. The website address to view the user manual is www.eaton.com/3105 You can contact Eaton directly, too. Eaton bought Powerware about 6 years ago. Here's the contact info. Be sure to have your serial and model numbers ready from the rating label on your UPS. Toll Free: 1 800 356 5737

If you battery packs are all at 130volts DC, then all of the packs will have become dead, and the batteries are not recoverable. Your battery DC bus voltage on a Powerware 9355 20 to 40kVA rated UPS is nominal 432 volts DC - 36 batteries in series in each string at 12 volts DC per battery. If batteries go below 10.5 volts DC each, or 378 volts DC bus voltage, no amount of charging will recover these batteries. You should not be recycling the DC battery breaker, unless you felt the battery breaker was faulty. The UPS would have given you an alarm message of either battery breaker Off, Charger Failure, or Low DC Bus Voltage long before the these batteries failed.
The battery test will not proceed if the batteries are dead.
