battery
battery is a macOS utility for Apple silicon MacBooks that helps limit charging and monitor battery status to reduce long-term battery wear.
What is battery?
battery is a macOS utility for Apple silicon MacBooks that helps users manage battery charging behavior and preserve battery health during long periods on power. It provides a menu bar app and command-line tool for setting a charging limit, commonly 80%, instead of keeping the battery full all the time. This is useful for people who mostly use a MacBook at a desk, want more direct control than the built-in optimized charging feature, or prefer an open-source utility for this task. The app can keep the charging limit active across restarts and can also discharge the battery down to the target level when needed. battery is published by Mentor Palokaj and is designed specifically for Apple silicon models rather than Intel-based Macs.
Key features
- Set a custom battery charging limit on Apple silicon MacBooks
- Keep charge limiting active after restarting the Mac
- Control battery management from a menu bar app
- Use a command-line tool for custom charge settings and automation
- Discharge the battery down to the target percentage when required
- Work as an alternative to macOS optimized charging for users who want manual control

Safety overview
Status: Use with caution
battery is legitimate software, but it changes low-level charging behavior and asks for administrator access to install the components it needs. That level of access is normal for its purpose, yet it also means the app can make system-level changes related to charging control. It may install helper components and keep the charging limit active in the background, even after restart. Keep it only if you intentionally use charge limiting, and remove it with its own uninstall option or documented removal steps if you no longer want that behavior.
Recommendation: Keep battery if you use an Apple silicon MacBook and want direct control over charging limits. If you do not use its battery-limiting features, you can remove it to stop background charging management and clean up its helper components.
