Over the years, laptops have come with new battery technologies to power your new improved processors and other components. Most laptops today come with lithium or nickel batteries with a designed capacity and rated lifespan.

Due to this limited lifespan, many users prefer to keep an eye on their battery health to get the maximum life out of their battery. If you too want to keep an eye on your battery health, here is how you can do it in Windows 11.

Laptops today use lithium and nickel batteries with a designed capacity and an estimated lifespan. As the battery is used, charged and discharged over its lifespan, it will slowly lose its efficiency and design capacity. Battery health is a measured percentage of your current battery’s capacity compared to your original design capacity.

This number helps determine the percentage of the original design capacity that is currently left in your battery. Battery capacity is measured in mAh or milliamp hours and you can easily find your battery's current capacity in mAh for a more accurate estimate of your battery's health.
