There are many guides on the net for this, I thought I would share how I did it.
This version of the mod is easier done if your RTC is mounted in a socket or if you desolder it but it can be done with the RTC still soldered to the board with some masking.
The nice thing about this verion of the mod is that you do not need to care about what RTC pin goes where and such, the only thing you need to do is if you remove the RTC then make a mark on the bottom of the RTC chip to keep track of pin 1 as the mark on the top will disappear.
Wet grind with a sandpaper until you hit the battery, remove the battery and you will end up with a RTC looking like the one in the picture below. I think all batteries are mounted with + up and - down but take note of polarity when removing the battery just in case. I used cable shoes because the cheap CR2032 battery holder I got diddnt have much to solder on, the cables are unnecessary thick and long.
