2007 Honda Civic Sdn - Odd sound after battery change

battery changed saturday
when i drive the can a sound
is heard under front of car
like a low siren sound
the goes away after about 10 minutes.
any ideas

Are you missing any pets since you changed the battery? :scream_cat:

Was the new battery fully charged before installation?

does the car have an aftermarket alarm system?

Why was the battery changed to begin with?
