Hi @dsank
Are you talking about getting a CR1220 battery with solder tabs (supplier example only).
If so, simply cut of the wires from the existing battery as close as possible to the battery and then connect them to the new battery. That way you have the connector connected to the new battery. Ensure that you get the polarity correct, red is +ve.
Do not attempt to solder wires onto a battery that has no solder tabs as you will have to apply too much heat which could damage the battery and also could be very dangerous to you to.
If the original connector is faulty for some reason, get a replacement battery i.e. search online for KTS 3a CR1220W 3.0V as trying to find the connector even though they are fairly common, may prove difficult as it could depend on knowing the specifications of the connector e.g wire pitch, distance between pins etc to ensure that you get the exact one.
