Hi Bob & all..
As far as I can see, the main reason it needs power is to allow the transmitter to stay in the OFF state during deployment and for 15 minutes after release, once it switches ON the battery can be depleted without any adverse effects.
This was talked about here on -bb a few weeks back.

RadioSkaf's Alexander, RA3WOK, just wrote me that they do, indeed, suspect battery failure of the ARISSat-1. Investigation and plans for deployment continue.
"According to preliminary information the problem is a failure of the battery ... "
"In the near future, batteries will be on Earth. It cannot be kept on the ISS."
"The situation will improve in June and July, when scheduled launching of ARISSat-1."
