Computer battery question

Daniel said:

So tomorrow my parents will let me open my new computer, it is a laptop, and well I've a few questions about the battery. It will be the first time using it so yeah, the battery is completely dead, how long do I need to leave it charging so the battery will last long? 12 or 24 hours? (Or longer) Also, can I use it while it is charging those amount of hours?

Lithium Ion batteries do not need to be fully charged like previous generations of batteries. They don't have a charge "save" point.

So should I just charge it until it is done? (100%)

The battery will have a longer lifespan if you charge it when your laptop is off and the battery is almost dead (if not dead). But like Adam said, you don't have to do that. You can have it plugged in while you are on your laptop using it and it can have any amount of charge remaining.

He is talking about how old batteries had "memories". The amount you charged it the first time would be the max it would ever charge. When lithium ion batteries were released this was no longer the case.

What I normally do with the laptops I have is charge it up to max and actually take the battery out so it just runs off the mains, so when you need to take it anywhere or move it you'll have a full battery.

Why don't you just plug it in and turn it on, and it will tell you if it's charged or not. And if it isn't leave it plugged in until it's fully charged.
