I've had the fx-451m since mid eighties. Replaced the battery a few years ago. Just carefully pry off the left side cover. Battery is in there. I think the battery is there to hold the number in it's (single) memory when light disappears. It works fine without the battery, so if you're shy, don't mess with the old jewel. There is nothing even close out there today that will actually fit comfortably in a shirt pocket. The closest I could find is a TI-36X. The old FX-451 dusts it in a 69! race!
