Low battery gage...but why?

No matter how much I run it the battery gage reads about 9 or so volts?( if that's what it's measured in) I have charged the battery two nights in a row and still it won't charge past that point. My battery is new from 9/15 and I disconnected it and clean corrosion from the terminals and reconnected it, it didn't help and I'm not sure where to go next with this, any help is appreciated. Thanks!

What's the actual voltage at the batt?

As sofa said, if you haven't, use a volt meter on the battery itself.

Re: Low battery gage...but why?

I Don't have one unfortunately. I'm gonna jump it tomorrow and try and get it to a shop and have them run some tests. Is it possible the battery could have been faulty? Or sat too long on the shelf? To me it sounds like a battery issue. It's an interstate battery

A voltmeter is cheaper than a trip to a shop.

If you didn't already know, the stock gauge is hardly ever accurate.

Re: Low battery gage...but why?

I Don't have one
Go get one.

"This bolt is loose". "Tighten it". "I don't have a wrench". What's the next sentence?

What's the difference between having the right tool to tighten a bolt (wrench) and having the right tool to diagnose an electrical malfunction (meter)?

As said, a meter is FAR CHEEEEEEEEEEEEEEEEEEEEEPER than "shop". PLUS, the NEXT TIME you have an electrical malfunction, you'll ALREADY HAVE THE TOOL, and we here won't have to read a bunch of P&M'ing about it. Instead of asking a bunch of mindless shot-in-the-dark "maybe it's this maybe it's that could it be this other" questions, you'll be able to FIX YOUR CAR.

Re: Low battery gage...but why?

Harbor Freight has some very affordable volt meters that will work for automotive purposes. Sometimes, they give them away for free with a coupon.

There's a HF in Reading, PA (20 mi drive).

Took it to pep boys and they told me is was the alternator. It cost me $15 bucks, and so I put a new alternator on right in the parking lot and now things are great.
