Some of your upper end laptop makers, and models have a battery recalibration utility installed. My panasonic Toughbook has one that I use about every other month. If you try to run it too often it will not allow you to do so since it is not the best thing to do often.
If I activate the software, it shuts down the OS, starts discharging mode, then it starts to recharge until full. You leave the screen open, if you touch the computer it will stop the process. It actually works pretty good. It gets my battery times dead on. When I have my Optical Bay battery installed as a 2nd battery the full discharge time can be over 14 hours! Nothing like a Toughbook
10 to 14 hours on both batteries, and that's with 1000Nit brightness.
