I'm not sure that all laptops support capping, and I'm not sure if Panasonic ToughBook supports the drivers necessary to cap. I guess you could deploy TLP and check
sudo tlp-stat -bI have a PC that I use as a router. It's power setup is inverter > lifepo4 battery > battery charger. Relevance here is that it's a "dumb" setup insofar as the PC can't manage the battery.
What I did to help with battery health is figured out how long the battery should run the PC and have a scheduled disconnect of the mains power for about half that time once a day. Not as good a solution as something that can maintain a ~80% charge, but better than leaving it at 100%
It'd work for an old laptop too, and can be accomplished with a cheap aquarium light timer.
Love it man. Nice use of non relational equipment.
it's not a toughbook and idk how to configure it but my letsnote cf-rz6 came with the battery charge capped at 80%, maybe it can be configured with their windows tool (or the acpi call made by that tool). i already have linux on it so can't check tho..
