I usually buy the packs of 48 batteries at Costco and the batteries inevitably wind up rolling around loose in a drawer or tub when the packaging separates. I finally got annoyed enough, while looking for Christmas batteries, to find a solution. I ordered a small and a medium rifle ammo case (my .45 ammo cases were too small) and inserted some foam in the top to keep the batteries from rattling or spilling out if the case is turned upside down. The partially used ones from Christmas (globes & music boxes) I'll put back in upside down so I know they've been used. Just thought I'd pass this storage idea along for anyone with the same problem.
