It has more contact surface, but appears to be no taller or wider than the edge of the printed circuit card. Yeah, I don't have a 3-cell 12C at work where i am now, but I have two 16C and a 15C and all three look like Alan describes [later edit: and has now pictured]. That fixed post that sticks into the battery compartment on yours seems to be missing its metal cap. If you were to fix that (and ensure a connection to the circuit is reëstablished, I would say you will be back in business. |
