You need to register the new battery for it to go away.
I also replaced mine the past weekend, actually yesterday thinking about it now. But in my case I had the software and cable to register the battery.
You also now that if the alternator goes that same light goes and stays on, so I would advice you to check in at a person with the diagnostic software to try and register the new battery and if light is still on to do diagnostics on your alternator to see if it is still ok.
Hope this helps:rollsmile:
