mike;I have one of the moultries also. I have taken 6 rools,(1 12expo; 3 36expo; and 2 24expo.) the 6 volt is still ok.they say to change the camra battries after 4 or 5 rolls if you use 24expo. or more. it doesn't say about the 6 volt.

I have a little tester I got at wal-mart for I think $6.00. it tell how strong the battries are. the 1 1/2 volts and the 6 volts.well worth the $$$ to get one.

I don't know why you would need to change that often though. my reg 35 mm camra will last for many rolls before changing. the 6 volt runs the sensors and all the d cell runs is the camra and flash.
