FWIW, during the east coast blackout a couple years ago, all flashlights, AA cells, and D cells were sold out from stores almost immediately. But AAA cells, C cells, 9V batteries, CR123A's, etc. were plentiful. So having some battery flexibility can be useful if you need to obtain batteries from your surroundings.


I concur. The blackout and the savage ice storm of a few years prior to that event taught me to have some flexibility in battery usage. In metro areas, all of the popular battery sizes; AA, C, and D were nearly impossible to find. In rural areas, they were impossible to find.

A couple recent trips to very rural areas also taught me not to rely soley on the odd battery sizes. During one very recent trip, we ended up having to drive 25 miles to a small city to acquire batteries and a couple other items we take for granted at home...
