New battry keeps running down
If your battery runs down when the car is off and not running, then you probably have a 12volt drain
killiongthe battery. If your problem occurs even when the car is being driven and used, then your alternator may be the culprit, it may not be charging enough. Attach a voltmeter across the + and - battery terminals. Start the car and let it idle without any accessories on. If you get a reading somewhere between 13.75 - 14.75 volts, your alternator is ok.
To check for a 12volt drain, disconnect the negative battery terminal and slowly scrape it on
the negative battery post 3-4 times. If you see any light to medium sparking as you do that, you probably have a 12volt drain killing the battery. BTW, don't be afraid of being shocked, no chance of that. This is extremely light voltage we're taking about here. Any 12volt drain is best left to a professional to trace down. Oh yes, a defective new battery is possiblity, but highly unlikely.
