I was looking for 18650 batteries online and Vape stores kept popping up , well they're like McDonalds and Stabucks I.e they are everywhere these days, so I guess that makes the batteries locally available now.
I can't wait to see if I can find a cheap source and buy a handful...
The best 18650's come free
(and in quantity) from and old Laptop Battery Back;
usually only 1 inside is bad, netting 2, 3, 4,or even 5 good batteries!
I have never purchased a single 18650 battery in my life, but have about 9 flashlights that use them, and spare batteries for every one . . .
(bought a $5 18650 smart charger - works great)
