@maccruiskeen @bhawthorne Well, of course I could open it up to see what kind of battery is in there. That's kind of obvious, isn't it?
The reason I haven't is that in my experience these things are fiddly and apt to self-disassemble. I'd rather not open it up and put it back together again, drive to the hardware store, and then repeat the process when I get home. Nor do I want to leave it disassembled while I go on my shopping trip.
The point is, it shouldn't be hard to find out. But it is.
@bodhipaksa @bhawthorne Sorry, I guess I didn’t account for the ‘remote is badly made junk’ factor.
