HP T750 G2 UPS (Uninterruptible power supply) doesn't work properly
Dear forum members!
I have a problem with my HP T750 G2 UPS (Uninterruptible power supply).
In case of a power failure, the UPS shutdown from battery mode after a few seconds or a half minute, maximum a few minutes.
The battery is alright (bought a few years ago) and has a capacity of 90% with approximately 150 minutes (without attached devices).
I tried it with a simple 25 W lamp and after I cut the power line, the UPS shutdown a few seconds later and the lamp is off.
Do I have to configure the UPS or what is wrong?

Re: HP T750 G2 UPS (Uninterruptible power supply) doesn't work properly
Thank you for the answer.
I have configured the UPS with the HP PowerManager:
Unfortunately the problem still exists.
I don't understand why the UPS shuts down with a 25W lamp attached after a few seconds?
I also tried a power failure without attached devices. Only with connection to the computer via USB. After about 5 minutes, the UPS gets in critical battery mode and then shuts down after a few more minutes.
Here's the log from the HP Power Manager:
Event Logs,07/18/2021 - 07/18/2021
Severity,Description,Date,Time
Information,<b> The UPS batteries are not fully charged. The UPS has started charging batteries.</b> ,July 18 2021,20:51:56
Critical,The UPS is in a low battery condition.,July 18 2021,20:42:14
Normal,UPS battery charge is normal.,July 18 2021,20:37:55
Warning,The UPS is on battery.,July 18 2021,20:37:55
Warning,Input voltage is out of range.,July 18 2021,20:37:55
I don't understand why the UPS switch itself off after about 10 minutes without attaced devices, although it was fully loaded before the simulated power failure. After I attach it after power failure to the computer via USB, it says about 85% battery capacity.

Is it worth to buy a new battery or does the UPS has a problem itself?
