I’ve been having a lot of trouble with my 2001 Hyundai Elantra. I have had it in and out of the shop and now, it’s just sitting until I can afford to fix the next set of issues. The current problem here is that my car will start with a jump but won’t hold a charge. I was told there’s a miscommunica…

The alternator is brand new. I thought that was the issue so, I already had it replaced. We checked it with a volt meter too and it was at a 16.

If the battery won’t hold a charge, it is shot, period. That doesn’t mean there aren’t other electrical problems, though.

We have tested another battery and it did the same thing

Tested it on its own or installed in the car?

A good battery will not not discharge in a minute or so. How are you testing the battery?

The battery has been checked several times. It had like no voltage. No power and this was after being charged and after being jumped. So that is why I was told it’s a miscommunication between the alternator & battery. I even charged it for hours today and it was completely drained as soon as I tried…

Yes, something is draining the battery completely but what?

Check the voltage at the battery terminals with the engine running after being started with a jump. If it’s at least 14 volts, there is no “miscommunication”.
