Does it work on battery mode only, or completly dead?

AFAIK it can't be started unless mains was previously supplied and
subsequently failed, if that is so then there is effectively no "battery
only mode".

As yet I've not put a load on it (I have to make up a O/P lead) as no LEDs
on the front panel light, its supposed to do a self test when the "ON"
button is held for a few seconds and its supposed to beep to indicate
status, it doesn't do that either.
