I received 2 different batteries from those that were represented in photos. If it was a look of problem, it would be nothing, the problem is that these batteries were announced for 1100 mAh and 3.9 Wh then they only 960mAh and 3.55 Wh. Batteries therefore less efficient! The product has been modified from visual, but you can not read the specifications and it does not match what I got! So in the end, with the seller, you do not know what you are buying!
