The OM's run up to as high as 12mA and even 18mA under certain conditions
(service manual for OM2+OM2N test spec is 12mA max in auto or manual). In some
circumstances they run a bit higher e.g. OM2/2N in B, 15mA. The in camera
manual battery test on the OM2N is specd as going as high as 18mA although
typically runs less.
The worst case for higher end OM's is probably display light on plus shutter
release. I would guess the OM2S with display light on and releasing shutter
could easily run up to 15mA if the ic does not shut it off?
OM2S spec:
7mA illumination viewfinder
0.5mA LCD on
5mA LED in viewfinder
13mA self timer
8mA Battery check
The OM4 specs:
illuminator 7 to 13 mA
Shutter 7-7.5mA
memo mode 3-5 mA
color mode 3-5 mA
self timer 4-6 mA
batt check 4-6 mA
shutter operation 8mA approx.
OM10:
Current not specified in service manual but
lock voltage 2.0V
Batt Check voltage 2.0-2.2V
