So my 1ds Mark III's battery charger busted a few days ago and I ordered a charger for it on batteryfly.com... wondering if anyone has used an original camera battery with an aftermarket or non-canon brand charger and had success. I'm supposed to receive the charger tomorrow but I also have a session tomorrow evening and I've just about shot all of the power of both of my batteries. I just don't want to be screwed at the session!!! The aftermarket charger says to use their aftermarket batteries, but I don't see why it wouldn't work with the original battery because the positive and negative prongs for charging are the same.. Any information would be helpful.. Thank you!!
