I bought these batteries without too much thinking, just in order to compare how the chinese semi-noname brands are holding up against the well-known marques. The batteries are manufactured in P.R.C. and yet delivered outstanding performance for their price. The first pack I discharged showed around 2100 mAh. However, I made a mistake while transferring the discharge curve to the PC and lost the data, so I went to the store to buy another one. Not only I got a discharge curve after all, but the second test served to have a sample at the manufacturing variance. As you can see, it performed even better than the first pack.
