Title: Works like a charm in a battery grip
Review: What's bad to say about a Nikon battery (or almost any product Nikon makes, for that matter)? With two batteries in my battery grip on my D90, I forget I ever have to charge them! I've taken over 5k pictures on just a couple charges and several of those included using the built-in flash as a CLS trigger. You owe it to yourself to spend the bucks and grab a spare, especially if you get a battery grip.
Is the review positive or negative?
