Could anyone assist, I wish to make sure I get correct replacement CMOS
battery before I remove old one. My board is ECS Sis 735KS5A Is there a
reference chart available please, unless you know type.

Thank You Roger in UK.

It could be one of the many versions of K7S5A.

The ECS site doesn't behave very well. I've had trouble with it,
and some of the trouble seems to be browser specific. In any case,
if you're lucky, maybe the site will respond for you. You should be
able to get a manual for your specific motherboard.

http://www.ecs.com.tw/ECSWebSite/ECS...&keyword=K7S5A

This would be an example of the manual. It must be unzipped to
get to the PDF inside. Well, unfortunately, the battery is not
mentioned in any tangible way. So we'll have to find a picture...

*******

Here is a picture of the board, which happens to show the legend on
top of the battery.

I see the standard type

CR2032

printed near the bottom of the info on the top of the battery.
A CR2032 should be available virtually anywhere (like RadioShack).
I think all the motherboards I have here (spanning ten years of
motherboards), use that same battery.

*******

You can see in the article here, the CR series are named according
to their dimensions. 20mm diameter, 3.2mm thickness. If you got the
wrong one, it would not fit the socket properly. Rather like
trying on shoes...

See "Lithium coin/button cells"

http://en.wikipedia.org/wiki/CR2032

I suppose there could be some temptation to stack two CR2016 cells
on top of one another into that socket. Don't do that!!! (Too many volts.)
The circuit expects a roughly 3V source. Once the battery delivers 2.3V or less,
it is time to change it. (2.0V minimum for the Southbridge, 0.3V for the
one way diode in the circuit path.) Those batteries are not supposed
to be charged, which is why there is a diode in the path to prevent
accidental charging. If charged, the battery would burst. Lifetime
is 3 to 10 years, depending on usage pattern (switching off the PSU
at the back, shortens the life).

HTH,
Paul

It's simple enough to just look ant the current battery and then buy
the same type.
