Battery size is measure in 2 ways. The actual physical dimensions of the battery and the size in Cold Cranking Amps (CCA). Purchase a battery that is physically the same size as the battery you are replacing or it will not fit. You can purchase a battery with a higher CCA capacity than the one you are replacing. This will cause no problems at all, and will just be a better battery, especially in the winter.
You might want to check with your local Chevy dealer. I believe that your battery should still be under warranty (5-year).

You have to take it to the a Chevy dealer to unlock with a code. For 15 or so dollars he will remove the code so this will no longer be a problem.
