Has anyone had a set of fresh batteries discharge significantly while sitting in an EOS? I put some fresh Duracell batteries in a few months ago. The light was used for maybe 15 minutes, probably less. I tried using it last night and the batteries are apparently discharged enough that it won't run on "high." (High and medium were the same brightness. All other modes worked fine.) I put in another set of batteries and high runs as it should. I'm puzzled - wondering if there's a parasitic drain in the EOS?
Found this thread, but it doesn't seem conclusive.
