Direct Methanol Fuel Cell ---future versions will provide up to 10 hours of battery life.
Well, I too almost bought a Acer btp abbm battery! But what you want to do, you decide yourself. Some people buy an extra battery just because it will act as a backup for them when the primary ones runs out of juice. A typical battery lasts about 2 hours before it goes down. I have a feeling that if you buy the battery separately from DELL, the price is dearer? Did you check that one out? I think it's in the accessories section of their website. A nine cell battery is a good choice because my colleague bought DELL's six cell battery and her battery goes flat very quickly. It also depends on what you do in the time the laptop is being used, the power saver options on my laptop determines how long it keeps going.

Any computer needs electricity to work. Laptop computers have an internal battery that powers the computer when you are away from your work desk. If you are return to your work desk or the battery is running out of charge you can still attach the laptop computer to mains electricity.
Most modern laptop computers may be used without the battery installed with no side-effects, other than that of the battery not charging. A few computers are designed to prevent you from operating the computer without a battery, so that you won't lose your work, if you accidentally unplug the unit, although the internal battery might give you a few seconds of time to plug it back in.
