Battery issue? and multiple warning errors on dash - ??

And and have the charging system tested. Most auto part stores will do that as well. You can also buy a decent tester online for $40.00 +-...
And make sure your batt terminals are clean and tight. I've seen a few headaches that were caused by nothing more than a loose ground terminal.

 

I concur. After playing games with a dead battery middle of July in a Walmart parking lot with ice-cream melting in a bag
I am now on the new-battery-every-2-year plan. I got 3 vehicles. All 3 get new batteries every other year on July 1.

 

Just parked my diesel tractor checked the battery date for giggles it's 13 years old! When it's parked it's not plugged in year around. Yeah at -10 it's marginal but it starts every time . It probably will go toes up tomorrow!
