1. What is the Windows 10 Battery Health Check?

The Windows 10 Battery Health Check calculates the current battery capacity compared to its original design capacity. This percentage indicates how much your battery has degraded over time.

2. How Does the Calculator Work?

The calculator uses the Windows 10 battery health formula:

Where:

• \( reported \) — Current full charge capacity (mAh)
• \( original \) — Original design capacity (mAh)

Explanation: The equation compares your battery's current maximum charge to its original maximum charge to determine health percentage.

3. Importance of Battery Health Monitoring

Details: Regular battery health checks help determine when to replace your battery and maintain optimal laptop performance.

4. Using the Calculator

Tips: Enter both reported and original capacities in mAh (milliampere-hours). You can find these values in Windows battery reports or manufacturer specifications.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my battery's reported capacity?
A: In Windows 10, open Command Prompt as admin and run "powercfg /batteryreport" to generate a detailed battery report.

Q2: What is a good battery health percentage?
A: Above 80% is good, 60-80% means reduced performance, below 60% indicates significant degradation.

Q3: How often should I check battery health?
A: Every 3-6 months for regular monitoring, or when you notice significantly reduced battery life.

Q4: Does this work for all Windows devices?
A: Yes, this calculation works for any Windows laptop or tablet with a rechargeable battery.

Q5: Can I improve my battery health?
A: While you can't reverse degradation, avoiding extreme temperatures and full discharge cycles can slow further degradation.
