As of other complains here (I had not read any reviews before ordering) was also given me a 700 mAh battery. I suppose that there is always such a battery is supplied, most customers will not notice.
Even if the battery is serving, there is therefore only 3 stars from me, because the battery is sold by specifying a higher energy content. 830 mAh of the original sounds better than 700 mAh.
