"Battery supplied is clearly a reconditioned battery packaging to the battery (used and dirty) and not new as advertised! the battery is full of micro-scratches but seems to work properly with theoretical capacity (10 / 12H), real capacity being tested on my 1001-HA. Being currently out metropolis, I had no choice but to keep it. I just hope it has not already served and she too held the "distance"! To be continued ... " However due to the above comment the company ANKER apologized for the inconvenience and offered me only a few hours after my post, exchange or refund of the battery. The reimbursement was made very quickly. Regarding the product itself, despite the fact that it was not new, but the battery is performing at least 7 hours with a mixed-use multimedia (movies / games / music / surfing ..) and WIFI permanent feature. Another plus I think its thickness vastly superior to other models enhances the keyboard at an angle like that of a PC. So I passed my note 1 to 4 stars because the product meets my expectations and I want to emphasize that the most remarkable reactivity ANKER. Congratulations!
