How to extend range with new batteries

[Bigmike101]

Noble ones,
I've got a 2022 Kona Electric 100KW premium, 39 KWH. 80% charges give about 150miles. However the adverse weather means the stated mileage is never achieved.
Can the 39 KWH battery pack be easily upgraded / replaced with 100KWH under warranty? Does Hyundai offer this upgrade? Has anyone in the forum done an upgrade to achieve higher range?

Can't seem them replacing it under warranty if it's not actually faulty.
If you're wanting to upgrade to the bigger battery (if that's actually possible retrospectively ??), then I'm sure there will be a very large fee involved !!
