In this article, we will discuss how you can check whether your laptop battery is working correctly or not.

Why Is It Important to Check Laptop Battery?

The battery is a crucial component of a laptop as it powers the device. A laptop with a faulty battery will not only lead to inconvenience but can also affect the device’s performance. A malfunctioning battery can cause the laptop to shut down suddenly or not power on at all. Therefore, it is essential to check the laptop battery’s health regularly.

Methods to Check Laptop Battery Health

There are several ways to check the laptop battery’s health. Below are some of the most common methods:

Method 1: Check the Battery Icon on the Taskbar

One of the simplest ways to check the laptop battery’s health is by looking at the battery icon on the taskbar. The battery icon will display the battery’s remaining charge level. If the battery icon shows a low battery level, it is an indication that the battery is running out of charge and needs to be charged.

Method 2: Check Battery Settings

Another way to check the laptop battery’s health is by accessing the battery settings. You can access the battery settings by clicking on the battery icon on the taskbar and selecting “Battery Settings.” The battery settings will display the battery’s current status, including the battery’s charge level, estimated time remaining, and battery health.

Method 3: Use Battery Diagnostic Tools

Most laptops come with built-in battery diagnostic tools that can help you check the battery’s health. These tools will provide detailed information about the battery, including its current status, charge level, and health. You can access these tools by searching for “Battery Diagnostic Tool” in the start menu.

Method 4: Use Third-Party Battery Diagnostic Tools

There are several third-party battery diagnostic tools available on the internet that can help you check your laptop battery’s health. These tools provide more detailed information about the battery’s health and can even provide recommendations on how to extend the battery life.

 Signs of a Faulty Battery

In addition to checking the laptop battery’s health, it is also essential to look out for signs of a faulty battery. Below are some of the most common signs of a faulty battery:

  1. The laptop battery is not holding a charge for long and drains quickly.

If you notice any of these signs, it is essential to get your laptop battery checked by a professional. Using a faulty battery can not only damage the laptop but can also be dangerous.
