Only if they are of different make, model, size and voltage!
:laugh:
Seriously: it depends on what you're talking about, REALLY.
Do you mean a cheapo made-in-China knock-off? They are mostly okay, albeit hardly ever useful to their hyped capacity.
Do you mean the 5600mAh one for the DVX sold here? That one is THE BEST, THE BEST I said (as long as you don't eat it!)
well, it looks like I have a chinese battery for more than one year, and I didn't have a reason to use it., yet.
It looks like a "big" dvx original, but little smaller, it fits perfecrly in camera. I got it in shity box and on batery, there is a sign : PAN D320Li2800. Btw, I live in europe.
