Anybody putting up batteries?
Not car batteries, but the ones we use in everyday items, like AAs, AAAs, CR123s, etc.
Of course, if it were to really go bad, and factory production were to grind to a halt, it could be years before things like batteries were to be made again. Therefore, you could never really store enough to last forever.
However, it would be nice to have lights, night vision (if you have it), and optics running during the "readjusting phase" to defend yourself while the "takers" are roaming around killing and pillaging. Once it all settles down and people get back to getting along and living, the "takers" will be much fewer and farther between.
At night, the headlamp is just so handy, but it needs batteries.
Also, lights and maybe toys keeps the kids settled that much longer while you get them more adapted to life without the electronic toys. They can be weaned off them, instead of quitting them cold turkey.
So I don't see batteries and the things that use them as being a "forever dependency" thing.

I'm pretty sure most here have some put away for short term times like hurricanes and such, just wondering if anybody puts any away for longer term.
