eBay is becoming the place to go for current Eee PC owners looking to get a little extra battery life out of their trusty little ultra-portable. While Asus currently has the standard battery available, they still have their 6-cell extended battery listed as coming soon. So once again we have the third-party manufacturers coming to the rescue, with extended batteries that are currently available and reported to offer up to 5-hours of juice. The extended batteries are 10400 mAh batteries and are selling for around $65. These batteries should offer much more time unplugged, which sounds like money well spent.
