These pull-ups, however, were not necessary when Ramozz battery. Have those things charged with my Frendlader, individually inserted into the camera, and both were easily accepted (firmware version: C 1.0 L 1.006). In forums you read that the use of third-party batteries by Nikon is inhibited even more sharply by downloading newer firmware. Just google it. The seller QUMOX therefore does not promise you the moon, but apparently has the right manufacturer found who could lock the Nikon chip crack (decoded battery!). It remains to consider how the decision to shelf the battery fails, I can not logically nocht review now. The two batteries purchased a year ago show anyway no fatigue.
Conclusion:
As amateur photographer who uses the camera sporadically, but then in a week shoots up to 2000 and more photos already sometimes, I am with the third-party batteries so far fared well, even with the EN-EL13 for its predecessor Nikon D50. And if you look at the price and compares with about 80 Euros for a stock Niko battery to the retailer, then the 15 euros are paid smooth. I will look at upcoming new purchases in any case after a comparable quality. Do better before clever than whining afterwards.
