I think this has been talked about a lot but I'm currently in this boat and am looking for guidance. Car has had an issue where the battery dies after 30+ miles on the road. i changed the battery out along with the alternator and it did it to me again this past weekend. I just recently found the dash option for battery voltage and under normal driving it stays at 14.5 volts I did see that under acceleration it dropped to around 12 volts and took a few minutes to get back to charge. any suggestions would be appreciated.
