Truck isn't starting !

[Big Z]

I own a 2019 Ram Rebel 1500 with 125k on it. My truck isn't starting. The battery displays 12.2 volts of battery and I replaced the alternator three months ago. I didn't leave it running or anything that would cause the battery to die. It does make a weird sound when I try to start it. Like it's winding. I tried to use a portable charger but it didn't work. Any advice would be appreciated.

If you hear a winding noise, maybe your starter motor is just spinning and not engaging the flywheel. Check the starter motor.
