    Hi all,

    I'm trying to get this old doorbell working. I bought some C batteries but they were too short for the slot. In the attached photo you'll see the exposed slot. The cover was lost a while ago so I have no brand name to go on.

    I bent the contacts inwards to fit the C batteries but they didn't work (I can't rule out a wiring issue but the doorbell has worked in the past). I think the actual dimensions for a battery that would fit are roughly:
    Height: 60mm
    Diameter: 25mm (give or take 5mm)
    And according to the markings inside the slot, each battery is 1.5V

    I can only assume if a C is too short then try Ds.

    Thanks guys. I did look at Ds and thought they might be too wide - will give them a try!

    Could you use a small PSU? It'll probably run on anything from 4-12v as long as the current capacity is enough - little chance of it overheating as it's only used in short bursts! (Unless you forget your key on Friday night and have to wake up the Mrs.) You could probably get one for less than the price of three Ds!
