[TenTec] Orion II battery replacement

[Stuart Rohre]

If you are changing any back up rig battery, it is good to make up a jig 
with an identical new battery, and bridge its clip leads across the 
memory battery connection points.

When proceeding to change the old battery, remove it carefully to not 
short the new battery and mess up your saved info.

Some instrumentation is designed to let you quickly pull out a battery, 
even main power, and swap in a new battery, without loosing any stored 
items.  But there is no easy way to tell that ahead of a swap.
