Is it reasonable to expect my battery to go bad while it is in the shop for repairs? I have 54,000 miles on my 2016 Explorer Sport. I had an issue with my keypad panel coming off, the airbag idiot light was on, and there’s was a recall for a carbon monoxide sensor. I did not have any issues with my battery prior to turning the vehicle in. Does this happen?

If the line techs kept cranking the vehicle to move it around or leaving the keyswitch on for electrical diagnosis without charging the battery as in a charger or sufficient run time to recharge, the battery can go into a deep state of discharge (sulfation) that shows as a bad battery on these new voltage only battery testers.
