Replacing CMOS Battery
I just put together a computer with an ECS K7S5A Pro motherboard. My problem is, when it is starting up, I get messages saying that the memory is wrong and the battery is low. From what I can gather from the other threads here on TechIMO, I should be able to fix both problems by replacing the batter. I have never replaced a CMOS batter before. What do I need to know? Where can I get the battery?

You need to know what kind of battery it is, usually they're CR2032, which you can buy from a normal shop. Flip the old out, and put the new in.

That's all there is to it? Just remove the old one and place the new battery? I don't need to do anything in the BIOS or on the motherboard itself? Sorry, I just want to make sure.

May not be the battery on that board. That is a common error message on the Ks5a Pro, along with CMOS checksum error and Defaults loaded. Particularly if you change ram or ram slots, etc.
It may correct istself after installing the OS and rebooting.

Nope. Removing the battery just loads bios defaults.
But do what dallasdon says first

It works just like normal batteries. Batteries dead, then get a new one. But i thought lithium lasts for 10 years...

Heh When I was doing civil service inplace of army (you know, an alternative for armed service) my boss claimed that cmos battery is a self-charging battery that will never run out.
It was a running joke through my whole service time...

I put the memory into a different slot. That solved the CMOS Memory Size problem. When I rebooted, though, I still got the CMOS Battery Low. I just bought the mobo, too, but it was a refurbished open box item. Any other possible solutions or should I really replace the battery?

I would just replace the battery anyway, there chep enough if you go to the right places. Try supermarkes, they have a high turnover so you should get a nice new one. Also, get a decent make like Energiser or Duracell, other are a bit crappy and wont last very long.
