Have you put an actual voltmeter across the battery terminals? If that voltage isn't high enough to start, you're sunk right there.
You also definitely need to know how the battery holds under load. Just because the parts store put your battery on charge for 30 minutes and "said it's fine" doesn't mean that it is. In order to validate that the battery is actually "fine", you need to fully charge it and then put a load on it and validate that it holds voltage while supplying the high demand for power. AGM batteries can be charged on a "regular" charger, but shouldn't be left on that charger once the charge is complete unless the charger has the proper circuitry to ensure that it doesn't overcharge it. AGM batteries can not be tested on a standard tester - they need to be tested with the correct equipment... My in-laws ran into a problem with their car a couple of months ago where the car had sat for WEEKS in colder weather. They finally went out after staying at home for so long... Stopped for gas, and the car wouldn't crank. AAA came, jumped it, told them the battery needed to be replaced (car is 3.5 years old, Subaru). Battery not readily available, AAA said they would call when it came in. A week later, it essentially happened again just as above. I wanted to do what I could to try and prove whether the battery was good or bad, so I brought over once of my Schneider charger/maintainers and connected it up. I was going to install the eyelet terminal right on the post connections. In the process of starting to loosen the negative terminal, I determined that the actual ground connection to the battery was loose. Tightened it, left the charger plugged in overnight, and not a single problem since. Our 'analysis' is that a repair to the AC compressor last fall required the dealership to remove the battery and they never tightened correctly. The problem slowly got worse until the charging process wasn't working "good enough". TL;DR - Electrical problems suck. Check everything that you can in terms of the basics (tight connections). Go over any work that has been done to the car, too, looking for possible loose or damaged connections in the areas where the work would have been done. |

If the car is throwing multiple unrelated codes, I'd doubt those are all legitimate. If a car has a nearly dead battery, sensors won't get clean and instantaneous power delivery when you crank the car and the computer will assume various systems have failed when they don't send sensor data back in a certain amount of time. I've unfortunately seen that myself on multiple cars of various makes and models where I'd let the battery drain.
When you do put a freshly charged battery that's putting out a proper 12.5 VDC or higher into the car, do all the codes clear, or do any still remain? So far, this is sounding like an alternator issue. I'm not so sure about that. It's definitely possible that it's still charging the battery but just not quickly enough. He said he can drive 100 miles and the car fails to crank after its been parked. Definitely not a total alternator failure, but it still likely needs to be swapped.

My mechanic said the alternator was bad but what was weird was that he was able to get the car to turn over with a hand held battery charger but I couldn't with either my parents malibu or equinox hooked up to it, both 2018s. |

These things can fail in weird ways, maybe even an intermittent short. So if it was shorted when you tried to jump, it didn't work because the short was drawing most of the current. Then maybe when your mechanic tried to jump it the short had opened up (these things can be heat dependent in failure) and was not fighting him, so the car turned over. Alternators now have built in voltage regulators. If the alternator side goes bad it can then cook the regulator circuits. Best not to rebuild alternators anymore unless you really know what you are doing. Replace the whole thing. |

I can't even update this post because my mechanic had to order the alternator thru my local dealer and each day the dealer calls me with a different excuse as to why it hasn't come in. And each day they say it'll come in 'tomorrow' but tomorrow never comes after a week already. This is why I hates dealerships

Hopefully your mechanic didn't get it in a week ago and has been "testing" it all week by taking his girl around town in your car? J/K Supplies and parts are backed up. A lot of manufacturers were closed down for a while. It sucks, but it is what it is. |

Even if they were cheap batteries, a good jump from a good power source should start it. Does it turn over normally but just not fire? |

Using this thing called "the internet" I could probably have this alternator on my front porch tomorrow. |

Not that long ago I ordered a t-shirt from a company just north of Detroit, and to get it to me just south of Detroit (a distance of about 15 miles), it took the USPS 14 days.! |
