I can confirm that this has been done on my 2015 XC90 T8.
I am currently running a hybrid battery from a 2021 XC90.
The previous owner performed the swap. The original hybrid battery had a smaller usable capacity.
After the swap, the car initially refused to start because the Volvo software still expected the old (smaller) battery configuration.
A Volvo specialist updated the software using VIDA, and after that the car started normally.
The State of Health (SOH) of the replacement battery is 100% — so in practice I now have a nearly new battery. It came from a damaged 2021 XC90 with only about 20,000 km on it.
So yes, it can be done.
But you will likely need someone with VIDA access, as a software update or parameter adjustment may be required.
[color=#ffffff]If you can arrange that, it might be worth trying.
