Netbooks tend to get pretty decent battery life when compared with larger laptops thanks to their low power processors. And when you add a high capacity 6 cell battery, you can often get 5 to 8 hours of run time on a single charge. But for some people that’s just not good enough. So one guy decided to take matters into his own hands and build a battery that provides 12-15 hours of battery life for an Asus Eee PC netbook.
Basically, he took apart a battery from an old laptop and wired them together with a standard Eee PC battery and then used a bunch of electrical tape to make tie the contraption together. The result is a rather bulky looking abttery that can run for up to 15 hours. It also takes 12 hours to fully charge.
