I did a search on this first and did find some posts but am still confused so will go ahead and post.

I'm about to replace my cmos battery because I lost my date/time after having unplugged my machine recently due to a lightning storm. This will make the 4th battery since I got this machine in Feb.,2004. My last battery was put in on Dec. 20, 2005. Isn't this a bit unusual? Shouldn't it last longer than that?

Thank you,

oops, forgot to give you my machine info but am running late for work & don't have time to go find it right now. All I know is that I have Windows XP SP2

Hi grits.
As far as the previous battery replacements were concerned, was the system power disconnected then too? (in all 3 cases)

A Cmos battery should last at least three years if the computer is connected to electricity for the most part.

Get a major brand - they are cheap enough.
