How to find CMOS battery in a Compudyne 4DX/33

I have had my Compudyne 4DX/33 apart and I can not find the CMOS battery. Does anyone know where it is in the computer?
Thank you.

Well you can refer to your manual book or instruction booklet that came with your laptop.

If it is a desktop then the battery does not look like a battery. It looks like somebody laid three doughnuts in a row on a table OOO and shrink wrapped them. You can still find these in the Internet but they cost about $20. I have my Mom's apart right now and it has a 4.5V alkaline battery generic replacement which should be a lot cheaper. There is a connector for it between slots 3 and 4 for add-in cards such as the video adapter. The connector is at the extreme rear of the computer. On this one the red wire is to the rear. The original was 3.6V I believe. 4.5V seems OK -- this has been in here for a LONG time

. Even a generic replacement may be hard to find, though.
