Nothing to add but you should listen to the people above who describe the CMOS battery. They know what they are talking about.
Shame on all of you who don't!

As you, no doubt, understand, computers do have batteries ... ALL computers have batteries. It's what powers the CMOS (Complementary Metal Oxide Semiconductor) which keeps vital information in your BIOS (Basic Input Output System).
In most modern computers, it looks like an enlarged watch battery. These are simple to replace. If, however, your computer is more than say 10 years old, you may find that the battery is soldered to the motherboard. If this is the type of battery that you have, I'd advise taking it to someone who knows how to handle a soldering iron. Heated batteries can explode if the heat is applied for too long.
When the battery is replaced, and you switch on your computer, you'll see a message stating that you will need to enter CMOS/BIOS setup. This is simply to set the time and date, and let your computer identify the type of hard drive you have connected, to enable sound (if your motherboard has onboard sound), to enable/disable any onboard graphics ... This may be important if you decide you wish to use a plug-in video card, otherwise you may have a conflict of resources.
Save the settings and then reboot, and all should be well.

I suppose you mean the battery on the motherboard, it keeps the time while your computer is off. There is a SLIGHT danger you could touch something you're not supposed to and cause an electric spark (bad). But not to worry.
Turn compuer off. Take off cover and see what the batter number is. See if you can get to it without too much hassle. Have a replacement battery. Lay computer case over so battery will not fall to the bottom.
My battery has a plastic ring around it. Using a jewlers screwdriver or a nail, there is a notch to pry it out with.
Replace the battery.
Reset the clock with the fired-up computer if your motherboard lost it's time.

I take it that you mean the CMOS battery on the Mother Board. This will cause the setup changes that you might have made to your BIOS to be reset.
If the battery is completely drained (a sign of this is that the time in win clock is always reset even if you change it) than this has already happened and you needn't worry about it.
If it hadn't it is best if you print out a backup of your BIOS startup menu with a program like Dr hardware so you can restore it from it.
Again, if no one has never made any changes in this menu, you shouldn't worry about it.

Desktop battery? It is easy. Open the case, pop the battery out and put the new one in. Make sure you unplug the computer.
