>I use my machine in closed clamshell around 90% of the time which means the battery is usually in pretty terrible shape after a couple years of use.

For those of us who usually use our MacBooks attached to the wall, deep discharging (AKA "calibration"; <https://www.newertech.com/batteries/power-calibration-guide/>) on a regular basis is a substitute, but is annoying to do.

I similarly went through batteries every couple of years. I now use FruitJuice (on the App Store) as the menu bar battery indicator. If it finds that the computer hasn't been used on battery long enough, about once a month the app guides me through running a maintenance cycle to run it down to 20%. I presume that following FruitJuice's advice is why my latest third-party battery is still at 103% health after more than a year.

Thanks for the tip, I'll have to give this a shot.
