2012 F250 Diesel batteries draining
We just bought a used 2012 F250 diesel. The
batteries had to be exchanged for the test drive.
We got it home, didn't drive it for 3 days, batteries
were dead. Took them to pepboys, cells were bad,
bought two brand new batteries. It was driven a
couple of times but then sat for 4 days and now
the batteries are dead again. Pepboys did a
diagnostic after the new batteries were put in and
could not find anything draining it. Any
suggestions? We're one week last the return date.
