I've had strange experiences with them, not as good as yours. I had a server 
which kept failing after a short period of operation. It was diagnosed with a 
bad power supply, which overheated and tripped the protection. After ordering 
and installing a new one the behavior continued.

Turned that half of the full wave rectifier in the UPS had died, so the battery 
would slowly drop until it cut out. Since AC was still on it didn't bother to 
tell the server it was about to die! After the server was off the battery would 
slowly charge until the server came back on, then the cycle would repeat.

I took great pleasure in recycling that UPS, I didn't want a replacement.
