Notebooks with greater autonomy

[pella]

Hello everyone, first excuse my English. Should I buy a laptop and the feature that interests me most is the battery life. I'd use almost exclusively with Office. I have no idea what is the range of a laptop, but could you give me some notebook models that can be done in my case, or at least what features should be able to have greater autonomy (processor type, battery type, etc.. ? The budget is not more than 800 € (but considering that I do not need great performance, possibly even less).
Thanks very much for your time and expertise.
