B batteries provided the high voltage to the "plates" of tubes. I recall 90
volt units. A batteries provided filament voltage (1.5 volts) to a lot of tubes like the 1EQ5, where the first digiot indicated the filament voltage, and the letters the type of tube characteristics, and the final digit the number of pins that were active. 6 AQ 5 was a 6 volt amplifier with two filment connections, a plate coonection and two grids. However sometimes there was a cathode too (I'm getting hazy on this stuff), maybe the filament didn't count as two. |

But I stand by the essence of my original answer - it was very incomplete, though, I see now. Tony |

Tis true
This continued for many years as remote farms had no electrical power Typical was two 45 Volt batteries -- Keyboard to you Hey I can buy A batteries, (AA, and AAA), and C batteries -- right What happened to the B battery ??? -- Keyboard In the Wilderness Tony In the beginning every radio, or virtually every radio, was battery operated.

I don't know if they're still made or not. But there were never really and consumer items that were designed for the "B" battery, that's why you never see them. Lots of people listened to radio broadcasts in the 30's and the radios all used B batteries. There were shoe-box sized "portable" AM radios than needed B batteries (90v ?). They were in common use until transisters became practical. I'll guess 1960. Tony -- Al Dykes ----------- adykes at p a n i x . c o m |

battery operated. They all used B batteries. It was only later that radio ran off AC line voltage. ______________ In the VERY beginning, radios used no batteries at all. Those radios were all solid-state, using a tuned coil of wire connected to a detector formed by a piece of galena and a "catwhisker," driving a headphone. RF |
BTW, your question brings up an interesting point.
You slightly mislead us by talking about battery sizes (defined by NEDA?) A, B, C, D, and AA and AAA But in the old days, the usage designations were widely used A was for filament, B for plate supply and C for tube bias. If your tube plates needed 90 volts, the grids might need 45. You used C batteries because to drop the voltage from a B battery was very wasteful (resistor heat), and batteries were expensive. The B batteries were almost always square or box-like, and C and A could be any shape. The D cells were used for illumination (dial lights and the like). Batteries could be designed for high current, low voltage, or low current high voltage, or some variation thereof to suit the purpose. Even today, if you go into Radio Shack and get the l;ittle coin-sized batterries used in calculators and the like, you'll have several different versions of the same shape. Some have their internal chemistry optimized for low current, long life (digital clock or memory battery backup in a PC), while others are designed for infrequent bursts of high current draw (garage door openers). That is why if you're in a bind, you can probably substitute another battery number for one that's not in stock, but it won't last as long because it won't be optimized for the job. But the size has to be the same, of course. |

They fell out of use after portables requiring a high plate voltage source were no longer made -- age of the transistor. I used to have one such radio in the 50s. I believe they pot out about 90 volts. |
