How to Get a Low Battery Alert at the Percentage You Choose on MacBook

With Battery Indicator

  1. Open the settings of Battery Indicator, and click “General”.
  2. Next to “Notify at percentages”, click “Choose…”.
  3. In the “On battery” column, select the percentages for the alert, like 20% and 10%.

The notification has the percentage as its title, like “20%”, and plays a sound. This is good when your battery is bad and you need an earlier warning than the one of macOS.

Tips

  • The “Charging” column is for the other direction, like 80%, to disconnect the charger before the battery is full.
  • “Notify when fully charged” tells you when the battery is full.
  • The percentages are 1% to 10%, 12%, 15%, 20%, 25%, 30%, 35%, 40%, 50%, 60%, 70%, 75%, 77%, 80%, 90%, 95%, and 97%.
  • If you get no notification, click “Notification Settings” below the settings, and allow notifications for Battery Indicator.

More about Battery Indicator

Without an app

macOS shows the battery level and battery alerts at the top of “System Settings › Battery”, and the same settings have “Low Power Mode”, which makes the battery last longer. Apple’s instructions.

To see the level all the time, show the battery percentage in the menu bar. If you look at the menu bar often, that is enough, and you do not need an alert.
