Download battery 1.0.4 (Mac) – Download Free

No matter how advanced your new M1/M2 Mac is, it’s still powered by a Lithium Polymer battery, which is under the most stress when fully charged and fully discharged. To ensure you get the most out of it for years to come, it’s a good idea to limit its maximum charge.

Battery is a very simple tool that does this for you. You can think of it as a stricter alternative to macOS’s built-in battery management feature, which only limits charging when it’s determined it won’t inconvenience you.

Great idea for long-term battery health

Li-Ion and Li-Polymer batteries (like the ones in the M1/M2 macs) degrade fastest when the charge is below 20% or above 80%. While it might seem counterintuitive to intentionally limit a battery’s maximum charge, the much higher degradation at full charge may be worth it in the long run.

This is especially true if you’re using a MacBook that’s mostly plugged in, as it’s always near 100% charged, which can cause a constant high battery load.

Unlike AlDente, this app has no fancy features and no paid features. You just fire it up, enable it from the menu bar, and go about your day. You can exit the app and it will continue to limit charge levels until you launch the app again and close it. It also continues to work after a reboot.

Although the GUI is built with Electron, which not everyone likes, it doesn’t matter because you don’t need to keep it running. What’s more, a command-line tool is automatically installed when you run the application, which you can always use instead of the GUI. The CLI utility also allows you to set custom charging limits.

A Useful Battery Limiter for Apple Silicon Macs

battery is great for users who don’t need the extra features of AlDente, users who prefer CLI tools, or even developers who want to make better apps of their own (the project’s license allows).
