My CMOS battery labelled CR2025 is running out, can I replace it with a CR2302? http://en.wikipedia.org/wiki/List_of_battery_sizes

Nope. Different size.

It's always wiser to replace a battery with the correct model, but you might just get away with it in using the CR2025 instead of the CR2032. The difference is that the CR2025 is slightly thinner than the CR2032. You may need to place a piece of conductive material between the battery and the connection. Be aware though that if you do try this, there's always the chance that the conductive material will end up floating around your system ... possibly shorting out your motherboard.
Play safe and go for the CR2025.

If you mean the 2032 (not 2302) listed, the only significant difference is the height 2.5mm for the 2025 vs. 3.2mm for the 2032 (.7mm difference). Since the battery is usually held in by a flexible metal arm over the top of the battery I see no reason why is shouldn't fit. The electrical characteristics and the diameter are the same. Just make sure the hold down is flexible and make sure you observe the proper polarity when you replace it. Good luck.

Mostly yes, depending on the age of your motherboard.
Old computers had rechargeable batteries, new ones have long life batteries.
Mostly, they do not cost more than a couple of pounds, your best bet is to note down the model number on your Battery and get a compatible one from any computer shop.
Play it smart and safe, or you may find your computer not playing as it should :-(

cmos batteries are made by different manufacturers and have different numbers, Be safe write down the number and take it to a computer shop or fair if you have one and get the same number .or a compatable one from another manufacturer

Probably not. Check the voltage rating on the battery. Make sure it's the same.
Obviously, check the size too!

You probably can but google your model number online and have it shipped to you.. best to stick with original specs..
