I am having a problem with my 2004 Volvo S80.

In the mornings when I go to start my car, I get a message skid service required. After I mess with it a little bit, the message goes away. I also get a message saying Immbolizer see manual. I'm getting a lot of weird messages all of a sudden.

I was told to change my battery to a high voltage. I have a 630 CCA battery but was told to get a 730 CCA. Could that be the problem?

I don't think a battery with a higher CCA is going to help, but a new battery in and of itself might help. I'd have it tested and see if it's voltage is where it needs to be. If the battery is worn out, you might be seeing the issues you are having. Putting a higher CCA battery will not do anything to improve your situation, unless the one which is in it is lower than it is supposed to be. Even then, a battery with a lower CCA if it's in good shape would not be causing these issues.

From SwedeSpeed: "It can range from a bad speed sensor, ABS sensor, bad yaw sensor, steering wheel position sensor of even a bad DEM."

Scan for fault codes.

Lots of "weird" problems seen at once can point to a bad brake module or mother module on these cars. You need someone with VIDA to access modules and read the codes, following the diagnostic flows from Xemodex's website.
