Battery gauge maxed after battery issues

2000 Cherokee Sport 4x4 4.0L

About a week ago, I took an early trip out of town to Charlotte so my wife could attend orientation at college. I was dead beat from not sleeping well the night before, and parked in the school parking lot and fell asleep for an hour or so. Woke up to realize I had left my lights on, and the batter was dead. Got a jump and while the car started each day over the last week, in the mornings it was a very slow start. Yesterday morning, it wouldn't turn over. Today, I decided to take the battery connectors off and clean them. One broke, and I replaced it. There was a fair amount of corrosion, which I cleaned as best as possible. I then jumped it with my other jeep and took it for a drive.

5 minutes from the house I went to turn around and the car almost stalled. I revved back up and noticed that the "check gauges" light was on. The battery gauge was buried at 19. I immediately drove home, turned the car off, and the battery is dead.

So...never saw the battery gauge do that before. Am I looking at a fried battery? Bad connection? Alternator?

Any opinions would be greatly appreciated.

Good question, you will have to test and inspect for all these possibilities.

Well, it looks like it was corrosion on the positive battery terminal. Something so easy. I took the wires out, cleaned up the ends of the wire, the terminal and battery post, jumped it, went for a ride and all was good. Started back up like a champ after getting back.

Whether it will hold a charge at this point, who knows. But a good bit better than having to get a new alternator!

My cherokee had horribly corroded battery cables, I ended up replacing them all with a 4awg set I made. Haven't had any issues since.
