I am using hp touchsmart tx2 notebook and its original battery that came with it is 240mah and it works only for 1 hour. I love to suffer internet daily nearly for 4 hours. So this battery is not sufficient for me. I want to get something that will give me 2-3 hours working ability. One of my friends wants to sale his laptop battery as he has one more with him. His laptop battery is 8800mah and I want to buy it. So can I use it in my hp touchsmart tx2 notebook?
