Update: Looks like this was a false alarm.
It appears Dell has quietly started shipping 24.4WHr hour batteries with the Dell Inspiron Mini 9. That wouldn’t be such a big deal if the company hadn’t originally shipped 32WHr batteries. Pretty much all of the review units the company sent to bloggers and journalists before launching the product had the higher capacity batteries, which explains why you may read reviews saying that the netbook gets about 4 hours of battery life while the machine that you purchased only gets about 3 hours.
Oh, and the Dell Inspiron Mini 9 order page says the netbook has a 4 cell, 32WHr battery. So if you happen to get a lower capacity battery you might want to try calling Dell and complaining. Who knows? It might do some good.

The Inspiron Mini 9 is configured with, and has never shipped with anything but, 32WH batteries. A third-party test software program being used in the field doesn’t properly program every vendor’s battery to report power (versus current) capabilities, and so the utility is not properly reporting the actual battery capacity. We have confirmed this and all packs are 4-cell 32Whr, and will deliver more than 4 hours of battery life in typical usage.
Latest news is that the original poster did a rundown test (and so did some other people). The “KR” battery that is reporting a smaller capacity (24Wh) does just as well (in fact, slightly better) as the “CN” battery reporting 32Wh. So not to worry after all: it seems to be only a battery reporting issue, but not a battery capacity issue.

How can I check to see which battery I have? Just received Mini 9 two days ago.
How can I check to see what battery, i.e. 32WHr or 24.4, that I have? just received Mini 9 two days ago.

If you look on Dell Outlet, they have 10+ pages of Inspiron Mini 9 returns. Doesn’t bode well for their market share
