  • Notes

  • This Zinc Carbon battery pack contains 3 x "B" Cells (U10). A more modern equivalent is the Varta Super 2012 3R12 (the R12 is IEC designation for "B" size").

    Commonly used in cycle rear lamps and pocket torches in the UK till 1980s and pairs in some German Transistor radios. UK makers perferred the PP11 if a centre tap needed or else a PP9.

    Originally about 2500mAH. As compatible Panasonic, Camelion, Duracell and Varta are available these can be used as source of U10/"B" cells to make more "authentic" replica packs than using "AA". An Alkaline "AA" however is about the same capacity as Zinc Carbon "B" cell. One supplier has AA adaptor.

    Connection type: short and long "Brass" strips

    Equivalents: BA6108 and many compatible size "3R12" packs.

    This Philco A3782 Battery valve portable uses the 1289 as power for torch built into tuning knob.

    The 3 x 1T4 filaments on the Sweetheart WWII covert radio used the 1289
