Nikon D90 Battery problem....

I have a D80 and recently purchased a D90. I seem to be having a problem with the D90 though. I have
2 Nikon batteries and 2 aftermarket batteries. The aftermarket batteries work fine in the D80 but
show as almost dead in the D90, even after a full charge. The battery meter in the D80 shows these
batteries at 100% charge but the D90 won't power up and the battery indicator in the top LCD shows
their just about dead. Both Nikon batteries work fine in the D90 though. Is this an
incompatibility ??? I called Nikon but since their aftermarket batteries they won't comment.

Anyone else run into this problem with aftermarket batteries ?????

Thanks
Brian

 

Maybe!! I know nothing about these cameras or batteries but can
confidently state there is a problem. They don't indicate a charge or
work in the problem camera.
I've seen a problem sort of like this with AA's. The camera wanted part
of the cell casing on the side to be not insulated. I would carefully
examine the contacts for some subtle difference but just use the Nikon
batteries. When it's time for new ones, you many be able to find after
market that specify the models in question.
