I'm so confused about this issue, or really, more of a hiccup.

Yesterday morning, my car started fine. Voltage was at 14-14.4 (I have a meter on my head unit) during the drive to work. After I was off work at 2:30pm, my car started fine, drove home, car sat for about an hour, then when I went to start it it was completely dead. Used a meter and got 3 volts. I jumped it, drove it around, and it seems to be working fine now with about 5 successful starts since it died and was jumped. Battery is 8 months old.

I'm 99% sure I didn't leave anything on, because ever since I jumped it, I haven't turned anything off that I accidentally left on.

Does anyone have any thoughts about this?

If you leave your car unlocked, can the battery drain? Because when I tried to start it while it was dead, the doors were not locked and I was able to get in without having to manually turn the key.

When alternators are going out, do they charge intermediately?

Go to an auto parts store that does free electrical testing and have it checked out.

Do you have a multimeter?

Did you check the voltage at the posts or the terminals?

First guess would be a bad connection at the terminals, leading to the no crank & low volt reading. Jump would disturb them & often make a better connection.
