[Kenwood] Battery pack

A simple sharp exacto knife down the seam seems to work wonders as well.  No
deformed plastic - just need a good epoxy to put it back together with.

First, before you go hammering on somnelthing like that, try a hair dryer.
Often that simple heat will break the glue loose, and you wont damage the
plastic etc.  I would also take the whole shebang down to your local "Batteries
R Us" type store.  They often can replace almost any battery pack, and do it for
a lot less money than radio stores do.  I have had several different packs
rebuilt by them, at a very cheap price.
