In the settings of [Battery Indicator](https://sindresorhus.com/battery-indicator), click “Choose…” next to “Notify at percentages”, and select the percentages, like 20%. You then get a notification with a sound at each one. Without an app, show the percentage in the menu bar and look at it.

## With Battery Indicator

1. Open the settings of [Battery Indicator](https://sindresorhus.com/battery-indicator), and click “General”.
1. Next to “Notify at percentages”, click “Choose…”.
1. 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.

- 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.

## Without an app

macOS shows the battery level and battery alerts at the top of “[System Settings › Battery](x-apple.systempreferences:com.apple.Battery-Settings.extension)”, and the same settings have “Low Power Mode”, which makes the battery last longer. [Apple’s instructions.](https://support.apple.com/guide/mac-help/mchlfc3b7879/mac)

To see the level all the time, [show the battery percentage in the menu bar](https://sindresorhus.com/guides/show-battery-time-remaining-mac). If you look at the menu bar often, that is enough, and you do not need an alert.
