I've known people who use the same computer for 5 years and don't even know what a CMOS battery is. So no, unless there's a problem with it you won't have to replace it often.

Its a watch battery... Will likely last just as long as a plain jane watch without all the lighting and doodads. So 5-8 years pretty easy. I have never had to change one on my own machines.

No. unless it's defective, it'll last years. Mine's lasted like 7+ yrs so far. Only neeed to replace it if your BIOS settings aren't saving and/or your time/date isn't staying accurate.

No. And you'll know when to replace it because the bios settings will reset to default everything you boot.

I've never had to replace one ever. As said above, you'll know you need to replace it if the BIOS settings and clock reset when you remove power from the computer.

I'll be damned... I think my battery might be bigger... Doubt it though as that makes no sense. I was thinking that the size of the battery will be as big if not bigger than most watch faces itself but that's a complex watch there. Must be pretty pricy.
