Hello, I have to decide between an Asus K551LN with:
i5 4200u, GeForce 840M, 3 cell battery 50 Whr and 4500mAh

and Acer E5-572G ( you won't find it on acer's site, apparent it's only available in eastern europe or something - you may be redirected on the US site, I posted the Romania site )
i7 4712MQ, GeForce 840M, 6 cell battery 2500mAh and I have no idea what the voltage is...

Both screens are 15,6" , both HD, the Acer has "comfy view" technology.

Now, I want to use the laptop for gaming, and some programming...
I know the Acer's specs are much better, but how will the battery be?

I know 6 cells are better than 3 cells, but the capacity is much bigger on Asus.
Plus, Asus battery is Li-Poly (sealed in); Acer's is Li-Ion detacheable...

I want to be able to use the laptop for at least 5 hours on battery, are those the droids I'm looking for? Or should I go with something else?
