Learn About Laptop Batteries

Laptop battery quick guide

What is it?

It is a part that stores power then provides it to the laptop as needed. It enables using the laptop on the go without the need to be plugged to a power outlet. All laptops come with rechargeable batteries. Batteries degrade with time and use. It is expected that your laptop's battery life decreases when the laptop gets older. Modern batteries have controllers that manage their charging and discharging cycles to maximize their life span. As a result, you don't have to worry about unplugging it to avoid damages. Just use it whenever you need it. The controller is taking care of it. Only replace batteries when the battery life becomes too short for your needs.

Batteries work by doing the following (over simplified) steps:

  1. Receive power from electrical outlet
