Nikon 1 V1 with tried, Nikon D800 and Nikon charger. A battery works, but empties much faster than the original battery. The second was for about 1 week in the V1 without use empty, can not load (more). Batteries includes Amazon from returning from ("dangerous"). Purchase price was easily refunded by the dealer (digital.media). If I just had bad luck or the inner life has changed since the positive reviews in May and June, I can not judge.
