Attempts to switch the relay are made first, followed by a delay of about 
15 minutes.

If the relay switch is successful and the shorted battery is taken 
off-line, the voltage should pop up instantly.  It won't creep 
up.  However, as I've said before, every test session ends with commands to 
turn the transmitters off, mainly to protect the transmitters from 
low-voltage damage, but also to keep the system drain as low as possible.
