Hmmm. Im pretty sure the ref checks the lights on all the bots to make sure they are turned on - so if no battery was connected then you had two points of failure, the team and the ref

also you would get a 'no data radio' led on the OI - indicating something was wrong before the match started

so in this case, if the ref allowed the match to start with one bot OFF - and he did not come over and say "your bot is OFF do you really want to play that way" I would consider it a failure of the ref

same as if he said ThreeTwoOneGO! without first asking each team if they are ready.

In this case - redo the match - ref failed to ensure the starting contitions were met.

if the battery became unplugged 3 seconds into the match, thats a different story - in that case I would let the results stand.
