Why You Should Remove Your Laptop Battery When It's Full


I can definitely tell you that there's a 100% chance that your Laptop's battery doesn't last as long as it used to when you bought it initially.


Sometimes you wonder if leaving your battery plugged in after it's full would spoil it and if you ought to remove the battery to save its battery life.


How Does a Laptop Battery Work?

Before I tell you if you ought to remove the battery, you need to understand how your laptop battery works.


There are two main types of laptop batteries: lithium-ion, and lithium-polymer. Lithium-ion and lithium-polymer are quite similarly, despite its technological differences. They both have different strong points and weaknesses, too.

For example, a lithium-ion battery has higher power densities but always suffers from compound degradation (the liquids inside the battery). On the other hand , a lithium-polymer battery is more robust but stores less power.

In both batteries, there are two truths you should know:

1. The battery can never be overcharged

If you leave your Laptop's battery plugged in all of the time, it won’t “overcharge.” When it gets to 100%, it will stop charging, and won’t charge again until the voltage falls below a certain level.


2.Fully discharging the battery will damage it.


Deep discharges may permanently damage the battery.

Should I Remove the Battery?



Yes, but there's a catch to it. Let me explain.

Your battery won't overcharge but heat tends to affect the battery negatively. During an intensive session like gaming, a plugged-in laptop potentially generates more heat.

Overheating a lithium-based battery is one of the top causes of long-term damage. In that case, if you’re going to use a laptop battery plugged into a power outlet for a long period of gaming, it would likely be best to remove your battery before proceeding.

Here’s the “catch” to it.

You need to decide when it's time to take your battery out, and when there just isn’t enough time to do so.


Another time to remove your battery is during a prolonged period when you won't be using your laptop. If you’re not going to be using the laptop for a couple of weeks, remove the laptop battery.

I suggest you charge the battery to 40%, then remove the battery for storage. This allows the battery to remain stable, without damaging it.
