There are many causes for the "Check Engine" light to come on. Most are related to the pollution control components of the vehicle. The primary cause, however, is the gas cap. Be sure that when you put it back on, you tighten it right up to the point it clicks then turn it another half turn (it won't hurt the cap). If the gas cap is on tight then take it to a mechanic and have them hook up to the computer to read the fault codes.

Will check engine light go off after I drive awhile since it came on after the battery was changed?

Replacing the battery should not have triggered the check engine light. The check engine light comes on when there is a problem with the emission system. Saying that, I would drive it for a while to see if the light does go out. If the light does not go out have the ECU scanned to retrieve the trouble code. Then use this code to diagnose the problem.
