I've had 3xAA alkaline's sitting in mine, just spring clipped it onto the original battery leads. My original was showing 3v when I took it out. Battery voltage is meant to be over 3.5 and less than 4.75.. I find it odd there's a 3v lithium in there, theoretically it would never have kept time or anything else. All the originals I've seen a purplish in colour.. not that means anything, whats yours look like?
