I have taken out the batteries and measured them with a multimeter. 
They put out 13V (they are rated 12V 9Ah).
Putting them back again and disconnecting the UPS from the mains it is 
kept on, powering all the connected devices.
The shutdowns only occur when the UPS is being monitored. Are you sure 
it's a battery problem? Do UPS perform further tests when they are 
being polled for data? I'll check with newer batteries then. I bought 
these one year ago :S
