The battery has “Pb” written on it, so I assume it’s lead battery.

    An alternative would be to replace the movement.

    Could be easier than fussing with the contacts.

      Bingo. I fixed or built clocks with these exact units.

      And you made me realize I can do this with an antique General Electric clock! It’s 120V and whines like mad, can’t get it right.
