I just purchased a new laptop and wanted to find out whats the best way to ensure that the laptop battery lasts long? Must you always only charge it when its nearly dead or is it ok to keep it plugged in the whole time?
 
Keep it plugged in. Cycling the battery(charging it then draining it) wears it.

Ideally you want to keep your battery between 25 and 75 percent.

Lithium ion batteries do not have memory, per se. They can sometimes accumulate digital memory which can be mitigated by doing a full discharge and recharge to recalibrate. It presents itself as inaccurate readings on time left (says that it has much more or less time than you actually have)
 
Hate to disagree, but that's precisely the opposite of what many battery manufacturers recommend! Constant 'topping up' counts as a cycle, and batteries only have a limited number of cycles (500, say many equipment manufacturers).

I can only say that by actually removing my laptop battery once it is fully charged and not needed during powered use, and by therefore not constantly topping it up (and giving it a good full cycle every month or so if necessary), I have kept my laptop batteries in good condition for years -- still got an IBM battery going from 2001, at just under half its original capacity!

One thing virtually everyone agrees on: that first charge is absolutely the most important; screw that up and your battery starts at a serious handicap. Most people believe that all-important first charge should be uninterrupted, and up to 24 hours depending on the equipment.
 
These were the exact conflicting opinions i read about when i done some research on google. Some people say do this, while others say no stay far away from that, rather do this. Lol. Anybody else who can provide more clarity on the issue?

Sorry, it seemed my post came across wrong...

I didn't mean you should discharge to 25 percent then charge to 75 percent then repeat. Rather, I meant that the battery, due to its physics, prefers a charge between those bounds. So if you were to disconnect the battery and store it, you should do it within those bounds, not at full charge.

I fully agree that charging and discharging between 25 and 75 percent would accelerate the age of the battery.

That's what I recommended in another thread yesterday, but it got frowned on :)

I think it also depends on how you use it. If you use it predominantly as a desktop replacement than this is the best approach, IMO.

Leaving it on charge while running does deteriorate the battery to a degree, so it will last longer. It's a bit like buying a new car and parking it off in the garage without driving it. Yes, you have a new car, but you don't get the use out of it.
