Attention! Have described As the previous speaker from me is the battery back on a long way. Now the laptop is a bit wrong. However, not so much that I find it disturbing. In addition, it helps at least for me even to heat, since it much better can suck cold air. It looks a bit strange, but it's quite handy in itself.
All in all a really good battery with a very good price. So far, I am absolutely satisfied.
