I inquired about the "B" cell battery a few years ago. Yes, they do exist. Or at least used to . Battery powered electric radios from years gone by.

Next to the left handed skikda blades.

Unless I missed yesterday?

Maybe because it's numbered? But I wanna know why there is no part 1!

We go to the bush and cut a tree down, then cut it up??????

I meant to say why there is no part 1, I got hung up on the alphabet....

Actually, there are no 'A' batteries either, I suppose A and B got replaced by AAA and AA as batteries got better at storing energy?

Really don't use a C much any more and D is getting rarer to use also, as the led bulbs have taken over and electronics get more energy sipping on the battery powered items.

Of late I see oddball batteries used more than the common ones, high output in odd sizes, for the big draw items. I try to avoid that, as you know where the cost and availability of specialty batteries will go....

A and B batteries were powering early radios (as electrification came to be) the A battery was 6 volt ish and powered the
filaments in the tubes, and the B batteries were high voltage, 60 or more volts in a pyle, to drive the voltage across the anode/cathode of the tubes. Jim

I think they still use B batteries in the UK.
A square 6 volt battery with the springs on top is really 4 F batteries.
They also have AAAA batteries.

Before electricity in a house their radios were powered by batteries. The "A" batteries 6 to 12 V or lower powered the filament of the tubed in the radio whereas the "B" batteries powered the plates of the tubes and were of a higher voltage and a low current usually 90 to 300 volts. Now you know more than you ever wanted to know.

That explains the term "B plus" when I was in Army Signal school.
The term was used, but not explained. This was in the day of
vacuum tubes. (1962) Thanks for the head up.

Never too old to learn.

Back when I was a young boy in the early fifties we had a battery power radio.
It took a battery about the size of a four pack cracker box.
It came in a box that had stamped knock out wheels and cab. I had a little cardboard truck to play with.
