I suspect that portable radios in the past (tube days) used F

The "F" designation was for "F"ilament use. Lots of old batteries had
1.5 volt filaments in the rectifier tubes, so you had an "A", a "B"
and an "F" battery.
Wrong. The 'A' battery supplied the filaments. the 'B' battery
supplied the plate, or B+, and the 'C" battery supplied the grid bias.
Some radios used a separate 'C' battery, and there a re reports of fifty
year old 'C' batteries still supplying the full terminal voltage. They
had no load when the radio was turned off, even though they weren't
switched.
