Similar to other hardware components, a laptop battery is a crucial part of your device. It is sensitive and can pose risks of fire or explosion if not properly maintained or replaced after extended use.

Instead of taking it to a shop for testing to avoid premature battery replacement and unnecessary expenses, let's explore checking the battery capacity using some reputable battery testing software listed below.
1. HW Monitor

The Handy HWMonitor tool is highly regarded and commonly used for accurate measurements of CPU, HDD temperature, fan speed, and more. Additionally, HWMonitor excels in checking battery wear levels on laptops in the Battery/Levels/Wear Level section.
