Why would the Check Engine light reset when the battery is replaced?

== my 2 cents== The memory in the computer is lost when the battery is disconnected for an x amount of time on this model car. All the self test the car has run (monitors) need to be performed again by driving the car. IF the check engine light was on, it will come back after it fails the test that it had previously failed for....most likley.
