CoreBook X I3-1215U Need New battery can't find correct one

My battery is swelling and has cracked the laptop case and pushed part of the case up.
When I look for new batteries on ebay, ali-express etc using the correct part number there are many different versions, but not mine.
There are some with the correct mounting holes, but they all have different wiring.
Mine looks like the attached photo, except it has a 10 pin connector with 7 wires.
I can’t find a battery with correct mounting holes and wiring simultaneously.
Do I need to buy a battery without a frame and re-use current frame? (I would rather not)
What are my options?
Thanks.
(NB its many years old)
