I've done two now and replaced them with Keystone1250 battery holders from Digikey, soldered on the reverse side
They hold nice big CR2450 cells now and can be easily swapped but it's a real pain to have to do this at all
It's almost forgiveable with RTCs, since they're generally not required for the main device functionality and RTC reference circuits invariably use coin cells. I've got an auto-darkening welding helmet, with its main power being supplied with the same planned obsolescence nonsense, despite having a solar panel on the front! It suddenly just stopped working, and my usual course of take-apart-the-broken-thing was thwarted due to its case being ultrasonically welded together. Only when I stumbled upon a random Youtube video of someone replacing the batteries in theirs did I get the oomph to pull the thing apart to change the batteries.
Same for me and the rice cooker battery, a random video convinced me it wasn't going to be too bad, Youtube is a great resource and I'm so grateful to those willing to share their experience!

It had the correct pin locations for my model of rice cooker
Here's the video that helped me: https://www.youtube.com/watch?v=yVege0o-quQ
