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?

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...

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.
