Removal of Internal battery & work on power

Yes, with a “but.” Let me explain. Modern batteries are vastly superior to their older counterparts. They don’t overcharge, and they don’t suffer from charge profile issues. 

Every battery can only sustain a finite number of charge and discharge cycles, after which it starts wearing off quickly.  

There’s no way to “overcharge” these batteries. When you get to 100% charge and leave your laptop plugged in, the charger will stop charging the battery. The laptop will just run directly off the power cable. After the battery discharges a bit, the charger will kick into gear again and top the battery off. There’s no risk of damaging the battery by charging it over its capacity.  

Leaving your laptop plugged in will not cause short term damage, but if you only ever use it on AC power you’ll almost certainly find that after a year the battery’s capacity has been significantly reduced. Similarly, if you only ever use it on battery power you’ll get through the battery’s discharge cycles quicker.  

So, the best solution is something of a compromise between the two: use it on battery power some days, and keep it plugged in on others. And in all cases, you’ll want to ensure it doesn’t get too hot.  

When your computer requires more power than the AC adapter can provide, it will stop charging to allow it to draw additional power from the battery. The system will resume charging the battery when the power demands are lower. This may occur during heavy gaming sessions. If the battery discharges below 30% while using the AC adapter, the system will stop using power from the battery until the charge is above 40% again.
