The battery provides the same power until it is drained. To stretch the time it takes to drain out, Windows cust down on performance. This can be adjusted by selecting a different power plan if desired.
Why not? I've done it and the battery does not charge or discharge continuously while it is charged to the desired level for months. I have no battery on the laptop as I don't have anything critical running. we have no power failures. If there is an electrical storm, I would unplug it.
I figured it out!!!!!!!!!!!!
1. just let the battery discharge to 40%
2. remove it while the laptop is on
3. put in an almost dead battery in case power goes off or whatever.
4. This way, you can store it in the fridge and keep it away from fast charging and charging over 90% damaging chemistry...
