Improvments to battery in newest line of blades?

So my current blade (early 2017) has had its battery start to bulge mid 2019 so had to be repaired.

the batterey swole to the point it was bending the trackpad and the bottom metal and the trackpad buttons were almost unusable, not to mention the sub 1 hr battery life (duh the battery swole)

This has made me hesitant about replacing my existing blade with one of the new line if this issue (seemed i wasnt the only one whose battery died in a similar timeframe) does anyone with the 15" whov owned theres for an extended period of time find any issues in terms of battery life or swelling?
