Battery voltage showing `14.03 with car on is the alternator good?

Asked by Mar 29, 2017 at 01:35 AM about the 2011 Toyota Corolla LE

Question type: Maintenance & Repair

My car's battery was dead, I thought I might have left the lights on. So I
jump started it everything worked fine. As I was driving all dashboard lights
came on and the car died, I pushed it over to the side, Jump started it
again took it to auto zone, they said it was a bad battery so I got a new
one. Have not had any problems yet, my battery was only 2 years old, so I
am thinking could it be the alternator? so I performed the multi meter test, I
got 12.5 with the car off, 14.09 with car on. and 14.01 with Lights and radio
on. All answers are appreciated Thank you.

Bad batteries do happen. I seen 2 year old batteries die before. The numbers are right for the charging system. Give it a few days and you don't have any problems, I'd say the battery was the culprit.

14.04 is a good number for a charging alternator. It don't get any better.

Bring the car to Auto zone and have them load rest the battery for free...

Alternator is okay, sometimes batteries just fail.
