A few years back, I bought in Hong Kong a speed grip for my Nikon D200
even with two new original genuine Nikon batteries, I've always got the message:
Low battery.
I guess Nikon want to make sure you buy from them genuine
and I don't blame them.
The store sold me the speed grip as a genuine Nikon.
Well, the copy was good enough to fool me.
