@linfos "but very small and with two tangs to re solder" how small is small. Check the diameter and the thickness. For the "CR" model the first two numbers are diameter of the battery and the last two digits are the thickness. So a CR2032 is 20mm in diameter and 3.2mm thin. Your battery could be a CR2025 (Diameter of 20mm and 2.5mm thickness) with solder tabs. Just like @andrewsawesome already mentioned, pictures always help:-)
