Battery asks why current should be balanced
In Windows 11 a new "sublevel" of the balanced mode has been added, which consists of maximum power saving. That is, you must use the balanced mode to access this sublevel. At the beginning I had the maximum performance mode but then I changed it to the balanced mode so as not to have the CPU always working at 5 GHz.

So why not just have the surplus of electrons on one end go to ground to equalize (e.g. 5 volts to 0 volts should produce current)? Why does it have to be the other end of the battery? I''m sure there''s atoms/molecules in the ground that could accept the extra electrons (receivers atoms/molecules for the donors in the battery).

A balanced battery is one in which, at some State Of Charge, all the cells are exactly at the same SOC. This can be done at any SOC level. In batteries that are regularly charged fully, it is usually done at the 100 % level. A BMS balances a pack by removing extra charge from the most charged cells, and / or by adding charge to the least charged cells. Balancing can be …
