A SELECTION OF EARLY BATTERIES, 1940's
Dry batteries and accumulators (item A1237) were common before mains electricity was widely available, batteries continued for portable sets, as they do today. The picture represents some of the large types that were used with domestic wireless receivers from 1940 to 1960. Bottom row left to right. Ever Ready AD3 90V HT and 1.5V LT, Vidormax L5507 90V HT and 1.5V LT, Drydex Red Triangle H1136 with 23 taps providing LT HT and Grid Bias, Top row left to right. Exide H1146 90 Volts only, Ever Ready 762 45 volts only. Exide DM538 90 Volts only, and Ever Ready B126 90 volts only.

Add a memory or information about this object
- In most of the 1920s H.T. batteries were absolutely essential to wireless set operation. However because they were disposable, there are very, very few that exist from before about 1934. In my research I have yet to see any colour photograph of an existing H.T. battery made before 1930. (There are examples of grid bias batteries from the late 1920s)
The lack of colour information and even accurate dimensions of popular sizes of H.T. batteries are preventing me from making museum grade replicas appropriate for U.K. wireless sets. (I have done this for my US made sets.) So if you know of any such battery existence, I would urge you to photograph and measure it as soon as possible and see that it is conserved properly. They are indeed rare. AND, of course, I would love to have the photos and dimensional info for my non-commercial efforts to display vintage radios in their proper context. BTW I do share my artwork recreations...
