Keeping track of batteries is a pain. We have to change them so much more often in our cameras now. Especially since the advent of live view LCDs and video. So, most of us keep a well stocked supply of spares, particularly with small juice suckers like action cameras.

You could just write numbers on them and just use them sequentially, but that’s easy to lose track of. Here’s a solution from Knoptop that’s simple and pretty effective, just using some small rubber bands.
