I had ordered me before June 10, 2014 this battery of Amazon, the battery was delivered in a anscheind Nikon original packaging. After the first time the camera battery diagnosis shows the value "2". This means 50% of life are still available. I then several times the battery drained with the camera, and charged with the Nikon charger. Unfortunately, the diagnostic value always belibt to "2". This EN-EL15 at this price is a sham. I can make this battery no longer complain because the 30 day period has expired. The Nikon EN-EL15 was declared when ordering through Amazon as "new". I am very disappointed by Amazon.
