5400 vs 4200 Battery

[snickers]

Is the 5400 battery bigger than the 4200, and does it stick out from the computer? Which is the one that comes with the Aspire One that contains 6 cell battery? I have the 3 cell version and am looking to purchase a battery that lasts longer, but don't want one that will be bulky. Where is a good place to buy the battery?

The One comes with the more powerful of the two, though I believe it is 5200 maH. The smaller one is actually the exact same size, just uses cells with a slightly lower rating. Either will work, though the 5200 will give slightly longer battery life. That's the one I am going to get in a little while.
