Is this bad?

They pretty much last forever or forever of the life of the mobo, unless you're like me and use it till its out of relevance then you'll only get the wrong date (much greater or less than the date you actually have) as a notice that you need a new battery or move up to a new platform.

The battery you're talking about is called a CMOS battery and it's a round thin battery (like a watch battery) and it's used to keep time (might be more). CMOS batteries take a long time to die off, I expect years before you have to replace it. 20 days will do nothing to it.

Edit: By the time you have to switch out the CMOS battery, you might as well get a new mobo, as there will be something better out on the market by then.
