Cummins ISX issue

I don't see what the batteries would have to do with the truck running rough and belching black smoke. The ECM will shut the truck down if it is getting less than 10 volts of power. The batteries are starting the truck, the truck is running, the fuel system runs off of a mechanical high pressure pump. The batteries would be the least of my concerns.

Poor battery's can throw vgt codes as well as supply low voltage to the sensors and ecm. I boosted a truck the other day with a dead alt and drove it in with 7volts. The whole dash dropped out and the truck still ran. Battery connections are the cause of many many problems. I'm not sure how we went from dead battery's to a bad tune?

UPDATE:
Left the trickle charger on for a day and it cranked up and ran great! Then my dumb ### left the cab light on last night and charger is back on it. Thanks everyone, I don't mind asking questions even though I've been at this for a long time. I like to hear others ideas on stuff
