New AA Alkaline batteries - camera says they are dead and shuts down

[olnacl]

To respond to a couple questions: the new Ray-o-vacs measure 1.60 v while the new Duracell measure 1.62 on a multimeter. Question would be, what do they measure under load? I suppose there is a battery tester that applies a load, but I don't have one. Maybe when I have more time, I'll rig something up so I can check the voltage under a load - just add a resistor, light bulb or the like I suppose. Maybe a trip to the rat Shack is in order.

BTW, it IS a Canon A570is, but I got the same experience from a new (to me) reconditioned Samsung
