About
Battery Mark is a powerful tool designed to evaluate your laptop’s power system and test its performance under extreme conditions.
Key features:
- Quick testing – Assess battery capacity in under 10 minutes.
- Full system test – Analyze the power system with a detailed discharge graph.
- CPU stress test – Fully load all processor cores for accurate performance measurement.
- Report generation – Save test results for future reference or analysis.
Quick Test
The quick test evaluates your laptop’s battery by measuring the time it takes to lose 3–5% charge. The results are then extrapolated to estimate maximum battery life.
⚠️ Requirements & Notes:
- Battery level must be at least 10% to start the test.
- The test ends automatically once sufficient data is collected.
- Connecting the laptop to AC power during the test will interrupt it.
Full Test
The full test provides a comprehensive analysis by discharging the battery by at least 50%. Unlike the quick test, these results are not extrapolated—they reflect real-world performance.
✔️ For best results:
- Start with a battery level of 90% or higher.
- Do not interrupt the test until the laptop shuts down due to low battery.
- Reconnect to AC power afterward to view the results upon reboot.
⚠️ Requirements:
- Battery level must be at least 60% to begin.
- The test ends automatically when the battery is fully discharged.
Results
After completing either test, Battery Mark generates a detailed report containing:
- Laptop specifications
- Discharge graph (for full test, includes a performance score)
- Option to save the graph as an image
- Option to export the report as an HTML file
