Battery issue

[Anonymous user]

We have one Smart-UPS 3000 RM 3U which connected with another spare pack battery. Last month, we have battery issue.The battery led is red, we disconnect all equipment then  press the Test button to run the self test to identify which battery need to replace. First time run the self test, it trip the power source. Second time, we disconnect the spare pack battery from the UPS behind, run self test again, no power trip and the battery led is gone. Third time, we remove the internal battery from the UPS, and connect back the spare pack battery, it trip again. Then we remove one of battery from spare pack battery to test one by one, one battery trip, another one cannot power on the UPS. So, we disconnect the spare pack battery power cable from the behind UPS, and run the UPS with the internal battery only.

However, last week the UPS suddenly no power, all equipment power off. Then we run the self test on the UPS (no spare pack battery connect), it trip the power source every time we run the self test. Then we connect back the spare pack battery power cable, run self test again, no power trip and no battery led warning. We charge the battery overnight, after it charge full battery, we see the time is 104 min ; However, when we let the UPS run without connect any equipment or power source from 10:00 AM, it run till to 4:10 PM then the battery is exhausted. It take total 6 hours.

So we don't know what the exactly problem for this UPS, please advice?

Thanks a lot.

Can you explain what you mean by saying "trip?" Does this mean UPS powers off or that the replace battery LED comes on?

Do you have any software/network management card installed in this UPS for us to review?
