Can a dead built in button battery used to keep date be the cause of AA battery drain?

I´ve had this camera for a little bit more than 2 years. At first there were no battery issues. But some months ago it all started. I charge my Ni-MH 2500 batteries I put them in the camera and if the flash is on then I take a picture and then get the message "you need to change the batteries". I try with all my batteries fully charge (I got around 20 different rechargeable batteries) and its always the same issue. If I turn of the flash, the battery last for several pics but not as much as when it was new.

Can this issue be due to the fact that the internal button battery (used to keep the date etc.) is dead? This internal batteri rechaargesw when you use your camera right? Maybe I kept my camera stored for too long and this internal battery discharged completely?

Any suggestions?

Built in button battery does not draw any power from the NiMh batteries because it is not rechargeable.

Your loss of power in NiMH batteries is most probably due to loss of capacity over the last 2 years. This lost of capacity takes place each time the battery is fully discharged. see FAQ's on NiMH

I suggest you switch over to low discharge batteries like eneloop made by Sanyo or NEXcell as advertised here
