I pulled out my OM-4 a little bit earlier today after not using it since last summer(ish) and found the batteries dead. I should say they weren't just dead, but were "swollen" a bit when taken out. These were good Duracell SR76s that I installed when I got the camera in May of last year or so. It had been stored with the switch set to "manual." It came right back to life with fresh batteries, but I'm wondering if this is symptomatic of the battery drain problem that some of these cameras are known for. I'm use to other cameras that use these batteries(Nikons specifically) going for years on end on a set of batteries provided that the meter is turned off. Can anyone comment?
