Were there 12V batteries in the 1940's?
Before WW2, manufacturers generally built individual 2v cells. They were packaged into batteries (of whatever voltage was desired) by their customers. The manufacturers were just starting to put groups of cells together, for their largest customers. 6v was obviously the most common, as it was requested by the automakers. But there were 12v and 24v batteries as well, for trucks, buses, and industrial EVs.
You can still see examples of these large single cells, as they are still used in industrial vehicles like fork lifts. The "battery" is a big steel box, and the individual cells slide into it and are wired in series on top for whatever voltage is needed.
