## What it is
A free, open-source CLI and menu bar GUI tool for limiting battery charge (e.g., to 80%) on Apple Silicon MacBooks to prolong battery longevity. It works by enabling/disabling charging via SMC and persists across reboots.

## Use cases
- keep my macbook battery at 80% while plugged in
- limit macbook charging to extend battery lifespan
- prevent battery overcharging on apple silicon mac
- control macbook charging from the command line
- set a custom battery charge limit on mac
- stop my always-plugged-in laptop from degrading the battery

## When to choose
- you have an Apple Silicon (M1/M2/M3) MacBook and want a free, open-source charge limiter
- you want both a menu bar app and a CLI with custom charge thresholds
- you want the limit to persist across reboots and app closures

## When to avoid
- you have an Intel Mac, which is unsupported
- you need advanced features like scheduled discharge profiles that paid tools like Al Dente offer
- you are unwilling to grant admin privileges for SMC access
