new battery is good news. your car will live longer once it receives one.
Don't do what I did. Drove my Audi A4 with its OEM battery to the point where if I stopped for 1 min and didn't turn the car back on within that minute, the battery would need a boost.
This in turn hurt my alternator. When I lock / unlock my doors you can see the door step lights and even headlamps being drained of energy / voltage.
Do the battery change sooner than later.
