With the original mercury batteries it did not seem to matter whether you turned off the light meter. When I first got my SRT101 in 1967 I routinely left the switch on for weeks or even months at a time. I suspected that the meter probably did not draw any current as long as the lens cap was on. When I took the camera in for a CLA about 10 years ago the original battery was still good.
