After the battery was replaced, the car beeps constantly.
The horn in the vehicle acts as a switch. Activating the horn energizes a relay, which powers up the electronic horn located under the hood. It is possible that the relay in the circuit has experienced a malfunction, where the circuit is stuck closed and is continuously powering the electronic horn. Have an experienced mechanic, like the ones here at YourMechanic, check the battery and cables for you.
