Want to know how much juice a 9 cell MSI Wind battery’s got in it? About 7.5 hours worth. At least, that’s how long the folks at Laptop Magazine were able to squeeze out of the pre-release, Mugen 9 cell MSI Wind battery they tested.

Laptop tests batteries by running a script that emulates typical computer usage, so I tend to believe their battery life estimates.

The downside of this particular battery is that it’s enormous compared to the 3 or 6 cell batteries that MSI ships with its Wind netbooks. It’s also heavier. The MSI Wind with a 9 cell battery weighs 3.2 pounds. With a 6 cell battery the weight drops down to 2.6 pounds, while the 3 cell version weighs just 2.3 pounds.

On the other hand, the Asus Eee PC 1000H weighs 3.2 pounds with a 6 cell battery. So if you can deal with the way this battery adds some bulk to the bottom of your netbook, you can have a netbook with 7.5 hours of battery life that weighs the same amount as a netbook that only gets 4.5 to 5 hours of juice. And as Kevin Tofel and I discovered, it’s hard to really discern the differnce between 2.6 and 3.2 pounds. They’re both pretty darn light when compared with a typical 5 or 6 pound laptop.

There’s another downside to this particular battery though. Laptop Magazine reports that it will sell for a whopping $180, which is kind of ridiculous, when you can pick up an MSI Wind netbook for as low as $350.

  1. I think the Samsung netbook is serving 7+ hours too with a six cell battery, so maybe LaptopMag test is very very tough.

  2. Not more? thats what my acer 6 cell battery gives me on the aspire one, without even running it on power maximization profile
