Can You Overcharge Your Laptop Battery?
But does charging it hurt its battery life if you are using it?
While overcharging isnt possible, keeping your laptop battery discharged is an issue.

However, the answer to keeping your laptop plugged in isnt as straightforward because it depends on several factors.
Lithium batteries are known for their unstable properties.
Similarly, an even lower charge at 70-75% (4v charge/cell) will quadruple the discharge cycles.
But this will also mean the battery wont last as long on a single charge.
Excessive Heat Causes Irreversible Damage
Temperatures over 30 Celsius can shorten a batterys life.
Even leaving your laptop at room temperature or outdoors that exceeds the temperature mentioned above can damage its battery.
Lithium-based batteries total charge-holding capacity starts deteriorating fresh out of production and will inevitably decrease over a year.
However,exposing them to elevated temperatures further reduces their ability to hold a charge.
Operating your laptop at high temperatures while plugged in at 100% battery charge isnt recommended as well.
Remove Battery When Plugged In?
If you remove the battery, dont store it in a discharged state.
Your battery will not last forever, and eventual deterioration of its charge-holding capacity is inevitable.
