I have owned many pc notebooks and they all had terrible battery life. I could only get around one hour of basic work after charging it once. But my brother and his friend get around 4 hours of work after charging their Macbook pro in which they are even running program which are lot bigger. So, I have query regarding this. Why are Macbook pro batteries better than PC Notebook Batteries? Also, is there any batteries just like Macbook pro batteries which can give me ample work hours on my notebook? If possible then do tell me about it. Please give an early response. Thanks.
