Do you know which codes you got?

Since you've replaced the battery, the engine map has probably gone back to default. New plugs will cause the engine to burn a bit differently and the ECU has to relearn. Give it a week then reset the codes.

Get yourself a scanner, read it, reset it, and see if it comes back.
