Back in the days when radios were big and stupid, they needed a bunch of batteries to work. The ‘B’ battery was like the boss of the radio tubes, giving them power to be loud and annoying.
My grandpa’s radio needed a B battery to blare Elvis at full volume. I swear it scared the cat.
My uncle tried to use a C battery instead of a B one. The radio just sputtered like a dying animal.
My mom’s old radio had a B battery that was so old, it looked like it was about to explode.
