Extreme battery life, but huge and difficult

When I got the battery and joined on my Acer Aspire 5742G I was once fassunglos. He does not engage 100% and is so high that it just 3.5cm raises my laptop in the air. Yet he sits stably in the bracket and will not fall out. For cooling, the increase is now also an advantage, especially for graphics heavy games, because the laptop now so enough air gets to cool. Logically, increases with such a large battery is also very strong, the weight of latops.

But he does what is expected of him in return? Absolutely!

At first showed me the battery indicator at max. Performance 12.5 hrs. Of battery life. What nonsense, of course.
However, the real term of 5 hrs. And 45 min represents a major achievement and is impressive. Anyone who wants to operate his laptop in sleep mode even 6 hrs. And 15 min.

Conclusion:
Heavy, huge but also very persistent!
Especially for people who her laptop in the field is therefore used very suitable.
For young professionals but still fluctuate between a Latop with this monster battery or an Ultrabook, which I rate the Ultrabook, because in the long run is the laptop bag like a bag of stones on the shoulder!
