Question About Battery Sizes?
I recently saw AAAA 1.5V batteries on sale at the store. I haven’t seen batteries this small before. What are they used for? This piqued my curiosity about another thing also. We have 1.5V batteries in sizes:
AA
AAA
AAAA
C
D
Why are there no single A batteries or B batteries?

Type A and B batteries are now obsolete. They were originally used to power automobile radios when they first came out in the late 20s and 30s. See link. I used to have a B battery that delivered 90 volts. And you think Tasers are shocking? That small battery packed a wallop. Meanwhile, C batteries have taken over what A batteries used to do.

A batteries are for cars
B batteries are those small little circle things that go in your watch

I think some Bluetooth Earpieces and other things use them.
BTW, they are also combined to make rectangular 9V batteries, and flat 6V J batteries.

AAAA (quadrupleA) cells are used in some long, slim l.e.d. flashlights, like this one http://www.brightguy.com/products/Streamlight_Styl...
