macOS 26.4: Charge Limit and Shortcuts
The Charge Limit feature, which lets you set a maximum charge to help extend battery health, was previously only available on iPhone and iPad.
[…]
Additionally, the new iOS 26.4 and macOS 26.4 betas bring Charge Limit to the Shortcuts app.
I like the current feature to automatically restore the charge limit the next day, so I don’t forget. But there are two problems:
If I know I’ll need more battery life tomorrow, I can’t turn off the charge limit before I go to bed because it will turn it back on at 6 AM. What I really want is for it to stay off for 24 hours.
It still takes a bunch of taps to go into the Battery settings and turn off the charge limit in the first place.
Shortcuts support should make the second part easier, and perhaps it can also be used to turn the limit back off that first morning.

Interesting.
FWIW I've used Al Dente since I bought this current Mac (a 3-year-old machine) to limit it to 80% with a scheduled full charge for the days I work on the go, and tracked the battery health of many machines with coconutBattery, which also has a feature to compare your battery's history to others with similar models.
The machines I had before followed the average of other users pretty closely. But this one, with Al Dente, is showing roughly half the degradation — a difference so big I find it very unlikely I simply lucked out. Limiting the charge does seem to have strongly positive effects, at least to those who use MacBooks in a mostly-stationary manner. (Apple's "Optimized Charging" has always been unreliable to me — constantly guessing wrong and charging to 100% on days there was no need for that, and the graphs show Al Dente is clearly outpacing everyone who has Optimized Charging on by default)
