These battery holders are a clear winner over other cell containers. Mine’s loaded with Eneloop AA & AAA cells (and a Duracell 9V), in my tool kit, ready to keep me moving. Regular Alkaline cells fit in there too, of course.
I’ve got a lot of small equipment that use these small batteries. Being prepared to change them when they’re low is easier than Periodic Preventative Maintenance like charging everything monthly or something. And less time consuming than zooming off to get replacements when something quits. Better for the cells, too, than charging them when they don’t really need it.
I don’t know yet if these will survive a winter, but the plastic seems of a type that should fare well. Certainly better than the other types of plastic battery boxes that seem to explode when the temps drop. A pretty good variety of shape/combos and colors are available.
While these do a good job of protecting the cells from shorts, they’re not absolute, so be careful about jamming them into spaces with other things that could lead to short circuits. Like my tool bag. And in a camera bag, no problems.
