I have an old computer stored up in my attic. Its from 1994, a P1 200 Mhz. For shame, her battery had run out. So I had a new computer. And it was forgotten, until now. Now my question is:
are all CMOS battery's the same?
That's the basic shape, yes. You do want to check the actual CRxxxx or whatever part # though, as the diameter of those style of batteries does vary. Also, there's often no need to hunt for the batteries online. Those types are pretty common; I can usually find them at my local drug store or Radio Shack for a couple of $$.
I guess i'm a bit 'rough and ready' in my own appraoch. I'd just grab the old one toddle off to an electronics store or other stockist, and tell 'em i want one same size, same voltage. If it fits it's OK!
The voltage is the crucial thing, because it powers CMOS and clock, and you don't want THOSE buggered up or there's gonna be problems!
Yeah just bring it in some store like RadioShack or something show them the battery and tell them you want a new one. Or just say you want a battery for your CMOS battery for your Motherboard I am sure they will give you the right one. Besides it's only what 2 dollars?
