BatteryGuard

BatteryGuard gives macOS users greater visibility into and control over how they manage their MacBook’s charging through a simple, lightweight interface.

The application continuously monitors battery charge and lets users choose their own upper charge limit and low-battery warning level. When a configured limit is reached, BatteryGuard can notify the user with a popup alert and warning sound, making it easy to know when to connect or disconnect the charger.

What BatteryGuard provides

• User-defined upper charge limit
• User-defined low-battery warning level
• Popup and sound notifications
• Continuous battery monitoring
• Simple controls for enabling or disabling alerts
• Low system resource usage

Keeping a battery at a high state of charge for extended periods can contribute to long-term battery wear. BatteryGuard provides a straightforward way to monitor charging according to your own preferences rather than relying entirely on macOS’s automatic battery optimization.

BatteryGuard does not modify the Mac’s charging hardware or replace Apple’s battery management system. It monitors battery status and alerts you when your chosen limits are reached, leaving charging decisions under your control.

The application is designed to remain lightweight and unobtrusive during everyday use.
