My battery died last week when it was really cold. I charged it up and 5 days later it died again. How do I tell if it is the alternator or ecu?

    Got to have it tested! Take it to a repair shop for this.

    Well, I went to local parts store and I didn't know they could test alt with the alt still in. Alt is good battery is bad. Also didn't mention the heat went out after I jumped the battery. That's why I thought it was the alt.
