Usually it has been seen that people who use laptops actually plug the laptop to the power supply. However this lithium stock is the wrong way of charging the battery. You should charge a battery once or twice a month. The battery should be charge fully at least 30 minutes before you start using it. In case you are going to use direct power supply, then it is best to remove the battery. This will ensure two things -- first, the battery since it is charged already will not discharge uselessly and second, it will ensure that the battery life is extended.
The processor goes up to 75-85C while under pressure but rarely dips below 40C when idle. Everything else is a bit cooler of course, but 40C in the computer case is rather common even with good air-flow. If you plan on using your notebook from the charger, remove the battery first left at 40% charge. Use an air-tight plastic bag and put lithium facts it into the fridge. Do not freeze.
Laptop computer uses: If you keep the battery in your laptop for everyday use, and power it from the wall socket, unplug the power every few days and let it run off the battery, as a battery at 40% capacity lasts longer than one at 100% capacity. if you don't travel with it, you should remove the laptop battery when on fixed power.
But that means that laptops need to have bigger batteries and bigger batteries mean bigger size. Laptops won't be portable and convenient to carry in this case. That's the reason why laptops have compact batteries that gives it a sleek look. But these batteries don't lithium bettery stock have good battery-life.
Briefly relating back to overall size... many lithium 18650's will differ ever so slightly in length (measured in millimeters). This is mainly due to an added protection circuit. The circuit helps to prevent the battery from over-discharging, since Li-ion cells can easily become damaged if their power is drained below a particular voltage. The protection circuit also prevents the cell from being over-CHARGED as well. These cells are very sensitive. They must be handled carefully, gently, and as described above, must never run-down too far, or be charged over and above their threshold. They can actually explode if severely mistreated!
