Low Battery light after new battery

I hope someone can point me in the right direction.

I have a 2013 Volvo S60. Almost a month ago, I had a dead battery. Since it was the original battery, I just assumed it had served its purpose and was due to be replaced.

Now, occasionally, not every time but probably at least once every day or two max, I'm getting a low battery message on the dash. I do get the BOOK TIME FOR MAINTENANCE message as well. I'd prefer to not be at the mercy of the dealership to know what's up. I'm just worried since it says Low Battery and it's a brand new one.

Does anyone have any insight to this? Thanks in advance.
