I assume you already found service manual sheet with all the data to be copied to paper for insurance. There is a super capacitor on the battery board, if it is still good it lasts long enough to desolder/solder the battery. For extra safety you can solder a parallel 3V battery with 10k-ohm in series. I think date/time is kept on a different board and it will be lost so don't be concerned if you see date to be wrong after battery change.
