Car wont start after flat battery
Hi all,
I went outside yesterday to start my car and it was dead. I charged the battery for a few hours and it would crank pretty strong but wouldn't actually start.
Next I disconnected the negative terminal over night and reattached it this afternoon and it was dead again, so I guess I have a bad battery.
I put the charger on 50amps to try and get it going so I could go to the parts store for a new battery but I got the same thing. I plugged in my ODBII but it didn't give any faults.
Neither the remote not mechanical key worked. The fob does lock/unlock the doors.
Right now, I'm at a loss. Everything was fine a few days ago when I used it. I'm open to suggestions before I get it towed to the shop.
Thanks,

Does your charger have a readout which tells you the voltage and if it's fully charged or not? Might just need more time on the charger.
However, it sounds like your battery is dead dead and charging it isn't viable. You'll need to charge it for more than a few hours just to give the car enough juice to start. Then, drive straight to your local parts store and install the battery in the parking lot. Or, ask a friend or family member to take you to get a new battery. Bring the old battery with you to avoid the core charge. The latter is probably the best option to be safe.

You can jump a car with no battery at all in the dead car. You're just hooking up a starter (and once running, engine, lights, etc.) in parallel with the jumping car.

It's a bluetooth one that I've used many times before on this and other vehicles so I know it works fine. I also used this method.

That wouldn't be possible. The ODBII needs power. I know it works, I monitored the voltage and saw it drop with the old battery when I tried to start. It works.

For those following along, it seems oil has been leaking from the engine into the alternator which is causing a voltage drop. $4200 later, I have my car back.
During the inspection, they noted that I need new front shocks, and both outer tie rods are worn, which is complete BS. I replaced them myself in 2019. I work from home, have done for 8 years. I only do about 3000 miles a year. There's absolutely no way they are worn out.

What did they do for this much money?

Alternator 330 parts 376.25 labor
Replace LH CV axle assembly (They said the axle nut seized due to rust and found thread damaged) 220 part 244.05 labor
Yeah, so that's about it. Runs fine one day, next it's $4400.
It would have had to go to the dealer anyway for the immobilizer and I get the 12 month warranty on everything. I know it's about as much as the car is worth, but I hardly drive it so probably going to keep it until it falls apart.

It's 1 minute to program keys.
We'll round up to an hour for the alternator.
About an hour for valve covers.
You don't replace RMS unless your half moon is dumping oil.
And they tore up the threads instead of lubing them, but even replacement is cheap and fast.
Just wow. I would've done all of that minus replacing VCs (waste of money) for $1,400 and still made fat cash.

I'm sorry, I have to be brutally honest. You got ****ed on labor... really ****ed... hard and dry. You need to find a new mechanic ASAP.
$2xx to change an axle, $3xx to change an alternator, $5xx to change valve covers? Those are each ~1hr jobs. A decent mechanic would have all of those finished in 2-3 hours and you got taken for $1000
