Usually how long does 6-Cell Lithium-Ion battery run on laptop?

How many hours does it run?

If my laptop battery dies for good, can I still have my laptop work while plugged into the wall?

It’s a Toshiba Satellite laptop, made this year, Windows vista, yadda yadda. Look my point is, if my battery gets wasted to a point where it won’t charge anymore, will my computer still work plugged into the wall? I can’t afford to get another battery. I can’t afford a pack of cigarettes.

How should I treat my laptop battery to keep it working a long time?

I just got a new laptop and I heard that one should remove the battery when the computer is plugged in to keep the battery from dying quickly. In my old laptop I left the battery in all the time, I don’t think I ever removed it.

Should I remove the battery when I have the computer plugged in? Should I just keep the battery in the computer all the time? Is there a difference?

Is better to leave devices (cellphone, laptop) with lithium-ion batteries plugged in all the time?

I thought you were supposed to charge them fully, then let them drain almost completely, then charge them, and so on.

But this month’s issue of PC World says that’s only the case for (older) nickel-cadmium batteries, and that current lithium-ion batteries have “the opposite problem”—does that mean they best keep their capacity if you leave them plugged in as much of the time as possible?

What’s the best way to charge a Lithium-ION battery cell?

I searched around on the Internet for some info about what I need to know, and so far, no such luck, so here goes:
I have a dead Laptop Li-ION battery pack in my possession, and i decided to tear it apart to find out how it works. Much to my suprise, 2 of the 9 cells in the battery pack had some charge left in them, so I destroyed the casing, and circuitry to get the cells out. I did some preliminary research online and found out that lithium is (obviously) very dangerous, even in battery form. Improper charging can cause damage to the cell (best case) to even a thermal runaway reaction leading to an explosion (worst case). Aside from that, lithium is very toxic, so needless to say, very dangerous stuff to play around with.
Which leads me to my question: How should I go about charging these cells to get some use out of them? Or is it just too risky to try? If I should just get rid of them, how should I go about this?
Obviously, I can’t dump these in the land fill, or can I?
