I was absolutely thrilled to find that I could purchase this charge "with" spare battery! Then I found additional batteries at 1/20 the price I would pay at Best Buy "if they had the right one" or even a camera store! I got 4 extra batteries and this charger, Now I could use this one in the car for less than 1 batterie at camera store! My kids soccer team is going to the AYSO nationals in Fla this July, Now I have enough memory cards (thx O) and enough batteries that I can charge two at sametime, one in car , one in Hotel and still photo the team all day everyday! I love shopping O-stock!
