Car won t start after changing alternator Reddit

Last week, I woke up and my car wouldn’t start. Got a guy to jump it, he tested the battery briefly and said it was 14 volts.

I drove to two separate auto shops (O’reillys and Autozone), and at this point the car would crank fine. They both tested the battery, said they thought my alternator was the issue but weren’t positive, so I got it replaced. My car has been working for several days after that, but I didn’t drive it more than 10 miles total.

This morning, it won’t start again. No clicking, no lights, nothing at all when I put the key in the ignition.

Do you all think it’s a battery issue? Or something else? I have a 2015 Honda Civic
