I am doing research on best practices for my lithium batteries and lifepo4 powerstation. There’s some conflicting opinions and variation for cycle numbers.
Will leaving my things plugged in at 100% hurt it more than constantly unplugging at 80% and replugging at 20%?
Well the battery in my phone lasted longer than my laptop. The difference : one stayed a long time at 100% the other one is constantly pliged and unplugged with 100%-20%-80%…, but also battery tech and management would be different (maybe).
Letting the battery at 100% stresses it and does degrade it with time, charging and discharging also degrades it. But it would be better for the battery health to keep it in the 80-20%.
However if it is easier to let the device plugged in, maybe check if it can run without a battery, and if not maybe it can be changed? Tho not sure if you can find replacement in some years.
Tho maybe the battery station could also be designed to stay at high charge? It isn’t the easiest thing to know how it works and how it is designed.
