I recently received a 2nd Nikon EN-EL3E Battery for my D80 back in Nov as a gift. However, no matter how I charge it, it doesnt seems to be fully charged. It will always be only half full.
Was thinking of bringing it down to Nikon service centre then realise I don't have the warranty card for the battery. Is a warranty card supplied with a new battery purchase? Or I can just bring down the proof of purchase?
