I ran the ATX-20HD for a year, but recently it has stopped working. I can jump the car, and it runs, but as soon as I shut it off, the battery turns off.

Going to send it back. Maybe the 30 is more appropriate? For most of the year, I could leave it connected for several weeks, and it would start the car no problem. If the battery is very cold, you can turn the lights on, for about 10 seconds - that warms it up enough to start. At least until recently!
One thing I'm confused about is:
You need to use a Lithium charger for it. But, apparently it's OK to use the factory charging system which is expecting an AGM. I don't get that part.
