My original battery has significantly lost after 7 months of performance and I had decided to go for the exchange. Now the anchor promises on paper battery with 2200mAh more capacity as the original. The increased output is also available, but because the original battery has 2100mAh battery and the anchor only 5% power packs on top of it, the effect is only slightly noticeable.
Bottom line, but remains a good battery to the undisputed good price, of doing what is expected of him. After 4 weeks of use, and a few charge cycles, I am thoroughly satisfied.
