I got the Patona battery for my Nikon 7100 as a replacement battery gekauft.Ich got him so far used 2 x to the end while shooting almost 1300 images in RAW format. A few short films were also present, about 50 x flash and considerations on the monitor. With the Nikon original I come at similar use to just over 1000 images. Which battery has two of the longer life, I can here but after short use not yet say. The Patona battery but has survived a fall from about 1.20 m on cobblestones and that speaks for him.
