The tubes listed here are later model radio tubes (1940's and later tubes).

Battery radio tubes are designed to be highly efficent. The heaters are typically at 1.4 volts or 2.8 volts to operate from one or two "D" sized batteries (typically referred to as the "A" battery. The plates are typically designed to operate at 67 volts to 95 volts, which is derived from the "B" battery. Typically the batteries used were 47 volts and 67 volts. In some cases a third "C" battery is used for biasing, but this is less common. While regular tubes have a heater rated at 150mA to 500mA, Battery radio tubes are normally operated at 20mA to 50mA of heater current. That can extend battery life significantly. Power output battery tubes are usually around 100mA to 150mA of heater current in order to provide the electron flow needed to operate a speaker. The plate supply and bias supplies are much lower current draw. Usually the "B" batteries last three to four times the "A" batteries. The draw on the "C" bias batteries is usually in the microamp range which means that the batteries would often last nearly as long as the shelf life of the battery.

When considering a tube project that will be operated from batteries, a Battery Radio Tube is the first tube type you should consider.
If you have lots of portable power available (such as in a car), consider looking at a Space Charge Tube.
Space charge tubes draw heavy on heater current, but only need 12 volts for plate operation thus eliminating the need for an additional high voltage plate power supply.
