Battery health is an important indicator of the overall condition of your MacBook. A battery with poor health will not be able to hold a charge as well as a battery with good health, which can lead to decreased performance and shorter battery life.
There are a few different ways to check the battery health of your MacBook. One way is to use the System Information app. To do this, click on the Apple menu and select “About This Mac.” Then, click on the “System Report” button. In the System Report, click on the “Power” section and then look for the “Battery Health” section.
