Re: Storing batteries in stocks, grips, etc.???
Pos to neg, but it shouldn't matter, no actual need to isolate, as long as they cannot make a circuit they won't do anything. All batteries even in origional packaging will loose charge with time, they all have the potential to corrode or rupture due to enviromental factors. Don't keep them in there forever and they'll be fine, if you're not changing them atleast annually you probably really don't need to pack them on the weapon.
