It's hard to order up the correct battery ... Ordered one "original" it is either expensive or at least a fake (despite Description 'Original') ... Buy one NoName, you do not really know what you get ... My choice was Ansmann, here you know what you get and there is probably no the abused branding Ansmann ... The battery is the same size as the original, therefore fits perfectly into the Nikon P100 ... Feels like the Ansmann holds a little longer by (it's just difficult to measure) ...
