And I quote;
"Before there were "chips", or even transistors, there were devices called vaccuum tubes which performed the same functions. In order to operate, tubes required two voltages: a low voltage to operate the "filament", or "heater", which generated heat necessary for the tube to operate, and a high voltage which actually did the work.
The low voltage battery in portable radios was called the "A" battery. The high voltage battery was called the "B" battery.
You can't find B batteries anymore because there is no need for them. So
there you have it!"

Because they are obsolete. B-sized batteries were once used as component cells inside zinc carbon battery packs, used to power the filaments for old radios and crank telephones. But electronic equipment has gotten smaller, and the old B batteries are no longer necessary to power them, so they stopped making them.

Why are 9 volt batteries rectangular?
