The above stated website gives you a clear idea on lap top bayyery overcharging.
They state that lithiun-ion batteries dont have problem of overcharging as they have a internal circuit to stop it but nickel cadmium and older batteries tend to overheat after many cycles of usage.

Check that on the battery you're using for your laptop. Or else search the model of your laptop online to know the type of battery.

I mostly use my laptop on continuous charging. I've a Lithium ion battery for my Sony Vaio SVE14A15, and there're no issues. Of-course battery tends to degrade after 3 years or so depending on how often you plug in and out the charger (i.e. your use).

Most of the modern laptops prefer lithium ion batteties due to their better capacities and less mainrenance.

It's goona explode bro.. just run away 😲 ..

Laptops have UPS functionality whether li-ion or xyz battery it doesn't matter. It depends on built-in UPS circuit which determines charge/overcharge or just keep idle after full charge.
Laptops are made to keep using on power source for optimal performance. Otherwise your battery will die quickly in this charging/discharging cycle.

Just think, you have a good inverter in your home. Does it overcharge the battery (see the indicator when it is charging) and after charging that light goes off.

I have left the laptop connected to the charger a lot of times! It is almost always because people forget to disconnect. And I've realized that over time users shorten the lifespan of their batteries by doing this.

From what I am reading the battery charging bit of a modern laptop detects when the battery is fully charged and stops the charging process. This means that, even though you have the power supply attached, the battery is no longer charging, but the laptop is running on mains power, and not the battery.

Not sure how true this is for different laptop models. Can someone confirm?

Yp ! that's exactly how it works. It Follows the UPS (The one which we use @ our Home/ Office) Principle.

To prolonged lifetime of battery stop repetative charging attempts.

Let it drain upto 90% then charge to 100%
Stop smaller charging intervals (if possible)

Applicable to even mobiles also.

** it is believed so...haven't read any proof.**
