They can, you (and I) just won't buy them at the price they have to sell them at. Lithiums are much cheaper.


I use alkalines all the time and haven't had problems with them in years. Except when I used the energizers that came with a flashlight. 2 months later they ate up the light. At least they replaced it.

I use duracell AA in the 10 or so flashlights around the house and in the cars (mostly 3 AA maglight led's that I bought at Sam's for 3.50 ea). In the house I replace them once a year and in the cars once every 6 months. The old ones that are still good I use up in high drain items that they only last a few days or less. Throw them when they are low.

I do keep lithiums as backups, for my edc light (a Maratac 1AA), in hard to replace items (my wind speed and rainfall sensors).


Respectfully,
