Regarding this, I have done this hack yesterday:

- Remove the battery from an existing UPS
- Rewire the UPS onto biggest car lead acid battery (12v) you can find.

Et voila! Bigger capacity. Put the batteries in parrallel and you do get 
monstruous UPS capacity... the only trouble with it is that re-charging 
the batteries may take some time.
