I don't have that exact model, but I do have a couple of Optiplexes at the house, and I usually have to hit either F1 or F2 to bypass (cannot immediately recall which one does what). It should just be that you have to replace the CMOS battery.

Try flashing the bios to the latest version. I rember having that error message on a dell destop but cant remember how I solved it, I replaced the cmos battery as well but still had the same error message. I think updating the bios solved the issue.

Another thing you can try is unplug the power plug, remove the cmos battery and then press the power button for five seconds until the flea power on the mobo has drained. Then replace the battery and plug in the computer, then see if this solved the problem.

with a low battery, usually the date/time is not correct -  so check that.
updating the bios -as said, can help, but realise that, in case the problems comes from a bad bios, or rtc chip, this may result in a bad flash = dead mobo

some bios have a setting to bypass all errors (the stop on errors setting : keyb, ram..)
worth checking too
