I'd say a Thinkpad T or W series are quite safe bets. With the 9 cell battery you'll get quite a bit more than 5 hours of battery and the keyboards are a dream.
Honestly if it isn't a Macbook then it is a Thinkpad. I myself have a Microsoft Surface Pro 3 but that is only used for coding part time, I have a big heavy "workstation replacement" laptop with a keyboard/mouse/monitor as my main coding machine(and gaming)
Agree on ThinkPad, but attention the models from this year on (model names finishing with 40) don't have physical trackpoint/-pad buttons anymore, the keyboard layout is less accessible, the models with touchscreen reflect so much you get headaches after 30 minutes. I sent back a T440 and bought a used T430. I am too worried about my next model.
