Low Battery Alert
Add a spoken low-battery reminder
This Rule combines a visual notification with a spoken message when your Mac battery reaches a low level. It is useful when you work away from power and want an additional reminder that does not depend only on noticing the battery icon.
When: The battery level falls to or below 20%. Do: Show a notification and speak the configured text. There is no If Condition. The sample notification title and spoken message say Low Battery Alert; replace the generic notification content with instructions useful to you.
Configure and try it
- Import using Open this Rule in Rulr and review the threshold in Battery Level Changed. Choose a level that leaves enough time for your normal next step.
- Edit the notification title, body, and sound setting. Review the Speak Text content separately so the spoken warning says what you intend.
- Allow Notifications for Rulr and make sure your audio output and volume let you hear the speech.
- Test the notification and speech Actions before relying on the battery event. To observe the full flow, use a suitable threshold and let the battery cross it while Rulr is running.
Requirements and limits
Speak Text requires Rulr Pro. The Mac must expose battery-level information. System notification visibility also depends on macOS notification settings and whether Rulr is frontmost.
The Trigger represents a threshold crossing rather than a repeating alarm every minute while the battery remains low. The Rule does not plug in power, save documents, enable Low Power Mode, or shut the Mac down. For a separate routine when you step away, see Mute and Close Private Apps When Idle.
