X200 Tablet battery

I have a little issue. My X200t will come with 4600 mAh battery. It'll do as a holder, then I assume it has to be 6-cell and up. My question is, what is the link between mAh, number of cells and actual battery life? Also if you could share your experience with batteries in terms of battery life I'd be really grateful, since I've no idea whether 4600 would be sufficient or w ould have to buy a replacement.
Thanks in advance

 

There's four and eight cell batteries on the X200t. If the battery sticks out the back, it's the eight cell. If not, it's the four cell. Generally, you'll get twice the battery life on the eight cell, all things equal, which they never are. The eight cell should provide six to eight hours of battery life when new, though a lot will depend on the settings and batteries do degrade over time. The four cell should be between three and four. If you need a lot of battery life, get the eight cell. If not go for the four.

 

All else being equal, the higher the mAh (milliampere hours) rating, the greater the battery life.

ZaZ's recommendations are spot-on. If you need great battery life, get the 8 cell; if not, then the 4 cell will be lighter/smaller.

 

Watt hours (WHr) = millampere hours (mAh) * voltage (V) / 1000 (mAh/Ah)

For the x200T 8 celll:

66.24 (WHr) = 4600 (mAh) * 14.4 (V) / 1000 (mAh/Ah)

Divide your total WHr by watts consumed (6-9 watts at idle depending on brightness in my experience) to get battery life.

Hope this helps
