Question about Powerware Best Power Unity/I UPS System

1 Answer

Unwaranted UT3K UPS check battery warning

The UPS is question is a Best Unity/I single phase UT3K. New batteries have been placed into this unit, they are maintaining correct voltage, and when the battery load test is run they pass. From turning the unit on after around 7 hours the "Check battery" warning alarm A-04 is displayed and cannot be cleared. If this unit is turned off and on again the alarm does not reappear for another 7 hours or so and the unit will also pass the battery test. I don't think there is anything wrong with this unit, but I don't like to leave it running with the alarm. Perhaps I need to edit one or more of the many many internal settings?
Any thoughts?

1) By the way, batteries are really new (or "China new")? ;)
If they really new then maybe not start-formed. In this case after little time they will get steady (end of problem). If they are "China new" - it worse, their real capacity usually less then 75% from declared.
2) Try to check batteries connectors, wires and their eyelets. If there is weak contact - charging will be wrong (low current)...
3) Check small orange (voltage sence) connector...
4) Look, what happened with P-62, P-63, P-74 ang P-75 settings? maybe there something is wrong...

Maybe, it will be helpfull?
P.S. Please, excuse my weak english.

Hi, Eaton bought Powerware in 2004 and assumed the service for Best Power products. Here is the URL for legacy UPS products like the Unity/I: You'll need to scroll down to the very end of the UPS section. In regards to parts and service, here is the contact info:

You probably need to replace the batteries. Although it probably has a Best Power logo, Best was eventually acquired by Eaton and they still service the type of UPS you have. You can call Toll Free: 1 800 356 5737 or e-mail:

What size UPS and make and model?

First make sure your utility is reaching the UPS and it's not on that end, sounds like the problem might be with your input power not the UPS.

If power is getting to the unit, you may have a failed power component internally, such as a fuse or transistor.
