Frequently Asked Questions
Everything you need to know about Battery Health Checker.
What is Battery Health Checker?
Battery Health Checker is a free and open-source tool for Windows and Android that helps you monitor and analyze your device's battery health. It provides detailed information about battery wear, capacity, charging cycles, and lets you set smart alerts to protect your battery life.
How accurate are the battery measurements?
The measurements are based on Windows' native battery report (powercfg /batteryreport), which provides direct access to your battery's hardware information. The tool uses the same data sources that Windows itself uses to report battery status, ensuring high accuracy.
Is Battery Health Checker safe to use?
Yes, completely safe. It only reads battery information and doesn't modify any system settings. The tool is open-source, so you can verify the code yourself on GitHub. We also provide SHA-256 checksums for each release to verify software integrity.
What are Smart Alerts?
Smart Alerts is a v1.0.0 feature that lets you set custom battery thresholds. You'll receive a notification when your battery drops below your low threshold (e.g., 20%) or exceeds your high threshold (e.g., 80%). Keeping your battery between 20-80% helps extend its lifespan.
Does it work on all Windows laptops?
Battery Health Checker works on most Windows laptops that support WMI battery information. This includes the vast majority of modern laptops running Windows 10 and 11. Some older devices or those with custom battery management systems might have limited functionality.
What's the difference between Setup and Portable versions?
The Setup version installs the app to your system with Start Menu shortcuts and auto-update support — recommended for most users. The Portable version requires no installation; just extract the ZIP and run it. It's ideal for USB drives or systems where you can't install software.
