Notes

  1. 6x "D" means cells in series, "D" x6 means cells in parallel
  2. The PP120is called a triple capacity Winner 120, though it may actually be only  double capacity
  3. AD3 replaced by B103 and B130 (high capacity) packs using layer cells for HT about 1946
  4. The 25mA series rather than 50mA series Radios start in 1953
  5. Connection Type H is B4 valve socket and Type W is Octal.
  6. We think only two sizes of snap used, but very many spacings. 
  7. The double ended HT batteries can have either size "snap" (Y or ZD),  recessed caps ("rc" not shown), proud Round caps (Rc both ends) or square caps with holes (T).
  8. The later BLR types are often round alkaline button cells in the square or rectangular case, so while better shelf life the actual mAH capacity is lower than the layer cells.
  9. The Vidor L5546 was replaced by L5550 = B148, no equivalent found and maybe used only on Vidor Lady Anne. Later Lady Anne models list the L5550.
