HP T1500 UPS just keeps charging and battery capacity keeps going down

[wielager]

We bought a T1500 UPS for our HP server in January. We're using the Power Manager software, which keeps a log. The log shows that it charges for hours, finally reaches a full charge, and then in a couple seconds starts charging again. Meanwhile the battery capacity reported in the log goes down from 98% to 95% to 93% . . .

After it got to 93% the first time we called up HP and they sent a new battery.  It happened again. They sent a complete unit. Now it's happening again. Is this just normal for an HP UPS? Will it just stabilize at some point and not go down further? Or is something wrong?

Thanks!

Hello,

I've newer seen such behavior with HP batteries. Do you have offten power failures? Or does it happen in normal operation?
