Any of you folks run lithium batteries in your cameras? I switched from alkaline to lithium in my first Cell Link in November. They definitely lasted a lot longer, but I saw an interesting decline. They stayed in the high percentage (above 85%) forever, then once they dropped below about 60%, they went downhill FAST. Like I said, they still lasted a lot longer in the Cell Link, I just thought it was interesting that they fell off fast once they started to go down on power. Anybody else see the same thing with them?
