more questions about the MacBook Pro, Core i5, 2.8 GHz (I5-4308U), model A1502 (EMC 2875), a model where I cannot disconnect the battery, because the whole case is closed, a model Im going to use to experiment with mac and create a partition to install a linux distro alongside the mac os.

My favorite notebook is a one that lets me take the battery off if I don’t need it. This way I’ve been able to need just one battery in the last 8 years. Regarding the mac, I’m going to need a new battery (it lasts 5 hours the most) and don’t want to waste charging cycles.

My question is twofold:

  • Is there any linux program that lets me manage the battery so I can choose to rely solely on outlet power, even if I cannot physically remove the battery?

  • the same question for mac.

    There are a number of commands an operating system can safely give to the charge controller. Examples include:

    • Run the device from external power; do not charge the battery
    • Limit/taper charge to X percent/voltage (assuming X is under the maximum)
    • Limit the charge rate to (something under the maximum)

    Lower-level control could potentially allow extremely dangerous operations like unbalancing the cells or overcharging the battery, which would be bad.
