I bought a Nikon D40 and decided to try an after market grip w/two battery capacity, this of course led to purchasing a second battery(purchased from Adorama a year ago). That battery lasted all of five charges. I would always use/charge both batteries at the same time and only noticed a drop in the PBL (private brand label) battery at the last use, then it would not charge at all while the factory original was still good for more. My best guess is that there is no internal circuitry (in the grip) to deal with each batteries load delivery. I now have another after-market battery from Adorama and have decided to use them one at a time to see if I can increase the life span...we'll see.
