We’ve already reported about some third party netbook battery pack which offers extended hours of use for netbooks which are longer than your standard battery pack. Now, guys over at the MSI Wind Forum have spotted that the 9-cell battery we reported not so long ago is already available for sale. The battery pack was tested to give 7.3 hours of usage for the MSI Wind, and that’s under strenous usage with the WiFi switched on. Sounds promising right?

But wait till you hear about the price. Said battery pack which is available at the UK channel of eBay was selling for a whooping $115! Aside from the expensive price, the battery pack is too bulky that it might no give your netbook a good look.

If you need longer hours of usage for you netbook, this might be a good replacement battery pack for you. That is of course if you don’t mind the high price.

Long Battery Life for your Netbook Doesn’t Comes Cheap

Found this 10400mAh Replacement Battery Pack for Asus Eee PC listed at Deal Extreme. The product page says it works with the Eee PC 7, 8 and 9 series and promises supper long runtime hours per charge. Unfortunately it doesn’t say how many hours one battery charge would last. But if a 6-cell battery pack could max out up to 7 hours of use, then we could assume that this 10-cell battery pack could max out up to around 12 hours or more?

The battery pack costs $49.90 with free shipping worldwide. Sounds to good to be true? That’s what some of the visitors say. But Deal Extreme seems to be a pretty decent online store though. So, I guess we need to wait for users who would actually buy the battery pack to find out if the deal is true.

I would really love to get one of those battery pack for my Eee PC 701. Anyone who would be brave enough to order, we will appreciate getting your feedback.
