I would not think a complete re-weigh would be required, but at least a
mathematical correction to the current weight and balance should be logged,
with information for CG with and without the battery in place.

There hasn't been a battery used in that position for
some time as the battery location is behind the seat.
I was thinking about carrying a small back up battery
in that position if I could find the OEM hold down
straps and I would definatly re-weigh the glider for
a new weight and balance.
Thanks for the comments and suggestions,
Brian
