Ok, here's a stumper. In the realm of 1.5V batteries, there are AAA, AA,
C, and D sizes. What happened to the A and B sizes?

What happened to the A and B sizes? > Dave Cornutt, Gould Computer Systems, Ft. Lauderdale, FL The A and B size batteries were used in REAL old-time radios. They were built to function with tubes in a 'portable' radio. The A batteries were, if I remember correctly, used to supply the heater current and the B batteries were used to actually run the set. Often the A size was a large, but regular looking battery. The B size was generally a wet cell and looked something like a car battery. Anyway, that is the best of my knowledge. I had a pair in the dim past, but they are long gone... -----Lawrence F.

They are commonly known as lantern batteries [...] Uhh.. one question.. it seems to me that the "A" battery would make a better lantern battery, as the filaments require high currents at low voltage (typically 6 or 12 volts), whereas the "B+" supply was (is?) considerably higher (remember the vibrators in old car radios?) at lower currents.
