Stop overcomplicating it... replace the battery.
You have a dead battery... It's an EX-battery. It has shuffled off this mortal coil. It's pining for the fjords. It has EXPIRED.

If a good cable-check, cleaning, and tightening, doesn't do it... buy a new battery, install said battery.

That may or may not solve the underlying problem. If he's only driving a short distance/time then a new battery will likely result in the same problem eventually.
