Check engine light blinking in many cases is due to multi cylinder misfire.
My first question would be, what was the code when you first got a CEL after the battery replacement?
Going on what little information you’ve provided:
Stuttered while accelerating then ok
No shake when I coast and stopped.
I might suspect a fuel delivery issue.
