I'm, very disappointed about this item,that I bought last year (like spare one) in a bargain offer, together with the camera. I fully charged ones and seems ok, but when I needed months later to replace the discharge one, I had to waste good time to try to sort it out the problem.(I try to recharge it again,the battery was dead). Now, I cannot complain to the seller,because the time is already running out.Fortunately was a cheap battery and then, in future I'll be thinking twice before purchase a non original product
