I had brought up recelling CMOS batteries before. Easy-peasy task with electrical tape and a CR2032 button battery, just be careful not to let the negative and positive short together. A convenient solution in certain circumstances, otherwise, it is easiest to buy a normal replacement. Now I understand how leads are normally welded on without solder: ultrasonic welding. I had no idea such thing existed.
