What kind of batteries are used in early radios?

There are two types of “C” batteries. These are the rectangular style for early battery radios. They are used as “B or C” batteries. The others are cylinder shaped, like the standard “flashlight” batteries. to the left are the early 22.5 types that were used in early battery radios for either B or C supply.

What kind of batteries do you need for a tube radio?

Connecting an A Battery. Many battery-powered tube radios require only 1.5 volts for the A supply, which you can provide with ordinary 1.5-volt “D” cells (flashlight batteries). If more than 1.5 volts are needed, connect additional batteries in series. Two 1.5-volt batteries in series will provide 3 volts DC, and so on.

Many are mains radios (Often in the same cabinet, AC, AC/DC or DC and battery versions are offered each year) and there are some large Radiograms in the late 1930s. Only a very few are not represented by Lissen versions.
