Battery saver activated question.
I just replaced the battery about 500 miles ago with a new diehard agm battery. The car has 16k miles on it. I was driving home 70mph on the highway yesterday with the wipers on for 1/2 of the drive for light drizzle. The radio was on too. The lights are set to auto. Everything is stock with the exception of a mild to wild controller. The battery saver message comes on. The console gauge shows the needle at exactly 12 volts. The drive was an hour long.
In the mornings when I start it, the needle looks like it is in the right place for a fully charged battery. Now I received the battery message before. I had the ac on and again it happened on the highway. The car also seemed it took a bit longer to start than it should so I replaced the battery. The car was from a warm climate so I just assumed the battery was spent. But I’m still getting this message. Is this normal? If not what can I test to isolate the problem? |

Battery was 12.8 at the post with car off.
Started headlights on it fluctuated between 13.9 to 14.7 With ac and read defroster, It settled down to 13.7 - 13.8 where it stayed (from dic). I believe it is a bad alternator? |

With ac and rear defroster on it should be ~14.7 Sure seems like bad alt. Did you check trunk grounds? Underhood alt connections too, never can tell.

I had the same battery for 7 years and never had a low battery warning. Voltage fluctuations in the charging circuit are normal, BUT:
You say your car is stock EXCEPT you have some "controller". Obviously, look there first. |

Sorry, I didn't mean to be rude. I had my email notifications off.
This was happening before I installed the controller. Everything looks good and tight. I get the Battery Saver message (rarely)... usually when I'm running the AC, radio maybe wipers and lights on the highway (for about 45 minutes) ...when I pull into my driveway. But the next morning, the volts are back up to fully charged and it starts like there was no problem. No codes either. Strange little car. |
