I bought this battery because of the very good reviews and because of the very good price compared to the original batteries for my new camera NIKON COOLPIX P510. The sale and delivery were very quick well done by the dealer. Unfortunately, I realized in my camera, that he was a trifle too thick when inserting the batteries. The built-in camera return spring underneath the battery is not pushed the battery upwards. I had to pry him. My remeasurement resulted in a deviation of about +0.25 mm in thickness. Surely only a slight deviation, but decisively. A mail from me directly to company Ansmann wg. This thickness variation was answered immediately. Within 2 days I got from company Ansmann a new battery sent free of charge, which also had the correct dimensions. I forgive 5 stars for the products for the merchant and for company Ansmann because the error was corrected immediately and without any fuss.
