>From Dalco Catalog, a 4.5v alkaline battery is listed for $14.50. (This is
the battery that is in my 486/586 computer.) I have also seen some
"universal voltage" batteries listed in catalogs, but don't remember what
they cost.
I had been noticing that the clock in my computer had been slowing down, so I
bought a battery a while back when I was ordering something (not from Dalco)
and it seems that I paid about $5 for it. Still haven't installed it though.
Several words of caution:
CMOS settings will be lost if a battery is not quickly replaced although some
CMOS will retain their settings for a couple of hours. (ref: Mueller's
"Upgrading and Repairing PCs")
New battery voltage *must* match existing battery voltage.
If you plug the battery in backwards, it can irreparably destroy your
motherboard!
BTW, have you gone to the Award site to see if they have a BIOS upgrade that
would take care of the roll-over date problem that Joerg mentioned?
Hope this helps.

How much does it cost to replace a CMOS battery on an old Cx486DX2-S/66 MHz
computer? Could I easily do it myself? Naturally I don't want to spend much
money on such an old computer.<<
