batctl is a terminal UI and CLI tool that lets you control battery charge thresholds on Linux. Set start/stop charge levels to extend battery lifespan, choose from built-in presets, and persist your settings across reboots — all from a single, zero-dependency binary. batctl provides a unified interface that detects supported hardware and exposes these controls in a simple terminal-based application.
The program offers both an interactive terminal interface and a scriptable command-line mode. Users can view battery information, adjust charging start and stop thresholds, and apply predefined charging profiles. The tool also supports persistence so that configured battery limits remain active across system reboots or suspend and resume events, helping maintain consistent battery management behaviour.
This is free and open source software.
