Why Aren't There B Batteries? (2022) (thebatterygenie.com)
The “B” battery is a type of vacuum tube battery. It is used to provide constant and positive plate voltage and is colloquially referred to as a “dry battery.” The “B” battery was a high-voltage battery commonly used for antique tube radios. It was available in various sizes and shapes, with a voltage range of 45 to 90 volts. Unfortunately, B batteries are now scarce to find, as very few vendors still sell them in some African and European countries.
