My brother's 2003 VW Golf (150,000 miles+) is having charging problems that do not have obvious solutions to us amateurs:

History:

- Left lights on a couple of times at work, requiring a jump.
- Sat outside on cold weekend, wouldn't start on Monday until charged up with battery charger.
- Had a flat tire and left flashers on for a couple of hours. Car wouldn't start, Tires plus said "2 battery cells are bad".
- Went to Walmart because battery was under warranty. They said "battery needed charge but is fine - get the alternator checked"
- He's been charging it every night after 1 hour of commuting.
- Autozone said battery is drained, but alternator is putting out 13.7 volts, slightly below the 13.8-14.5 range but they think alternator is okay.

Is this something that has a common solution for this model or does it require a real technician to ferret out?

Put a new regulator on the alternator the brushes are included. Like this but check the number of yours and google the part#, its an easy external bolt on.

I don't think there's much wrong with the car. The output voltage may be on the low side. A voltage regulator may help it, or may do nothing.

Tell him to quit running his [censored] battery dead.

How do we know the charger is good? What voltage do you see from the battery charger he is using?

How clean are the terminal connections?

I certainly would not trust Walmart to tell me my battery is fine! I would have battery tested again.

From having similar "phantom" issues occur from time to time, I bet the battery is no good.

Go to a different Walmart, or go at a different time. The usual policy there is to not ask questions but just change out batteries when someone comes in. Or be more assertive and tell them that you've had the shop test the battery and determine it is not GOOD ENOUGH for your particular application.

+ I guess I misread the post I thought AZ found 2 bad cells and Walmart changed it. Time to use the reading glasses.

Exactly. Even a battery the readily starts the VW may cause problems. Very sensitive to voltage quality. I didn't think Wal-Mart even sold AGM batteries, of course I've never bought one except from the VW dealer. Not a bad price either.

Walmarts have pretty good battery testing machines. As long as they are operated competently.

Here they use a Midtronix with printer same as AA, no idea how accurate that is at determining if its good or bad.
