- They're still around, just not used very much; they were
- for vacuum tube portable radios. The A battery was a large,
- low voltage battery (6 volts, I think) for the tube filaments.
- The B battery was the high-voltage battery for the tube
- plates; they came in various voltages, starting at 22.5 volts.
- You still see them around some, but they're not very common.
- The terminology is still with us though; the power supply in
- radios is still frequently called the "B+" supply.
