Why this tool exists
Most people don't think about their laptop battery until it's already too late — when it barely lasts an hour, or the system suddenly shuts down without warning. Windows buries battery data in verbose report files that most users never see.
Battery Health Checker was built to change that. The goal is simple: give anyone instant, readable access to their battery's real condition in seconds, not after digging through command-line outputs.
Instant diagnostics, no fluff
Run the tool and get all the information that matters about your battery in one clean interface. No installation required — just extract and run.
Health Percentage
Current vs. original design capacity at a glance.
Cycle Count
How many full charge cycles your battery has logged.
Wear Level
Degradation measured precisely, not estimated.
Full Battery Info
Manufacturer, chemistry, serial number, and more.
Nothing to hide
The entire codebase is public. You can read every line before running it on your machine. Contributions, bug reports, and suggestions are all welcome.
Made by <e/dev>
Hi, I'm Lotfi Boukhemerra — a software developer who builds tools that respect your privacy and run entirely on your own machine. Battery Health Checker is one of several side projects I maintain in the open.
I built this because I kept getting asked by people why their laptop felt slower than before, and the answer was almost always the battery. So I made it easier to check.

If the tool helped you
Battery Health Checker is free and will stay that way. But if it's saved you from buying a new laptop or helped you catch a battery issue early, a small tip goes a long way.
