Given the good price I had no great expectations, and it has also come. The battery empties extremely fast (at the beginning of this review pulled the plug, now 92%), you can watch almost the battery icon in the status bar when emptying. However, the original battery was not Laufwunder for netztfreien operation of HP Pavilion dv7, in my opinion is totally unsuitable. (Current state: 91%).
Therefore, it was just important for me to have a battery that will I ever again can reasonably operate (the power) the notebook. It was only later I found out that the notebook works even without battery.
(Current state: 89%)
So if you expect more from the battery for this notebook type, should rather invest more.
