1.5v silver oxide batteries have a very stable discharge curve. They 
perform  the same as mercury batteries with a stable voltage output 
until the end when they die rapidly. 1.5v alkaline batteries have the 
gradual discharge curve you are complaining about. Never use alkaline 
1.5v batteries in camera equipment.
