Asus Zenbook UX31A RTC Battery Replacement

The RTC battery in my 12 year old Asus Zenbook UX31A started to fail so the clock would get reset. I found out it is possible to fit a small CR1220 battery holder into the space where the previous battery used to be. So I re-used the connector and soldered on a small extension wire to the battery holder. This works well and now the battery can be more easily replaced in the future.

Here are some photos for reference:
