Paul you are absolutely right. I measured the camera at the bench with
a 3.00V supply and this is what I measured on my used OM-4T:
idle or M60: 6-8uA 6-7 years
meter on: 650-670uA 28-30 days
light on: 10mA 40-50 hours
I don't know how many mA-hr the batteries are, but assuming
400-500mA-hr, the batteries should last: with the light on 40-50 hours;
meter on 28-30 days; idle 6-7 years.
