check all your connections and make sure your grounds are clean and tight

have you checked if its actually charging?

Have you checked all your grounds? Corrosion or shorts on any wires? Voltage drop on all cables going from battery, alternator and starter? Did you get your alternator from Autozone? I replaced 5 starters one time before getting a good one from Autozone. I would get an OEM alternator or Denso. Not sure what they use. See if computer controls your voltage on your model. You could have a bad PCM if this is the case. What is a voltmeter reading when car is on and you are touching battery? Low or high?

Sadly having the same issue from Firestone. And then having to just get a diagnostic is almost 200 at acura. Argghhh!!!

Having the same problem charging system keeps showing and a battery sign

Acura TL 2011 with the same issue exactly, . Do anybody think if could it be bad fuse or relay?

it could be your Bluetooth running in the background when your car is off and draining your battery. I suggest disconnecting the Bluetooth option and seeing if that helps
