Battery mode seems to be called "Battery Charging Charge Mode" that can be set considering the life of the battery itself.


It seems that battery life will extend instead of driving time of about 80% against full charge, so it is recommended if there are many uses with battery.

When there are multiple batteries, it is also possible to change this setting depending on each. It is quite fine-grained.


Heat radiation control is also possible, it can be set from "Power Options"
