I've heard some say that the coin cells used on computer mobo last a decade or so because they get trickle charged when computer is on, but I've never seen anything but regular CR types in every computer I've built or scrapped. But even sitting in the factory packaging, new cells don't seem to last that long, not that I've had one for 10 years!
