Why are there AA, AAA, C, and D batteries, but no B batteries?
I have a question. Why are there AA, AAA, C, and D batteries, but no B batteries?
That's a great question! The reason there are no B batteries is due to the history of battery technology. There used to be a B battery, but it was a carbon-zinc battery that was replaced by the modern AA battery.
