People will buy this battery. The original battery of Acer's real scrap against. Maybe he keeps just 2 hours, depending on what you're doing. And Acer will cost the whole time loving a mere 79 euros. Hello There? Are you crazy? This battery here is not only making 6600mAh (the originals has 4400mAh!) No, the term is also extended considerably. In my case up to 3.5 hours, ie total 5.5 hours. Of course, depending on the operating somewhat less. Pleasant is the fact that the battery has a built-increasing, so more air can come under the laptop.
