What could be the problem if your car will not start after running on a brand new battery after a month?

The alternator probably isn't putting out properly. Go to AutoZone and have them check the alternator. If the new battery went completely dead, and you know the alternator is good, the culprit could be a "slow draw". This would be caused by a trunk light that stays on when the trunk is closed, a vanity mirror light, glove compartment light, console light; something that you assume goes out when it's closed, but doesn't. Check all of your courtesy light switches in these places to make sure they make proper contact. A glove compartment or console door that doesn't close properly could be the culprit. Until you find the problem, disconnect your battery when you're in for the night! If you can't resolve it on your own, find a shop that has a low amps probe. It'll determine where the draw is coming from.

Your battery meter in your car is running high whats the problem?
could be the regulator
83 Celica charging light and brake light on all the time replaced brand new alternator and brand new battery the problem does not go away what else could be the problem?
Should give more info. Did they come on at the same time or days apart? Could you have 2 problems not just one? If they both came on together you could have a wiring problem. If it has a sensor for the light in the master cylinder it could just be low on fluid, bad sensor or damaged wiring to sensor. Have you checked the output of the alternator with a digital multimeter? Check it at the alternator first, should be 13-14 volts while running. You can check it at the battery also, again should be 13-14 volts while running.
What if your battery meter in your car is running low What is the problem?
If the battery meter in the car is running low, you probably have a bad alternator or a shorted cell in the battery. There are other possibilities, but these are the most likely. The regulator fuse could be blown, but that usually means a bad alternator.
Could the problem be the alternator or voltage regulator if a battery won't hold a charge in a Mazda miata?
Could be a bad battery Check the chatging system with a voltmeter--a fully charged battery should read approx. 12.8 volts without engine running With engine running reading should be approx. 13.8-14.2 volts
What could cause the battery to not charge in a 1999 Chevy Tahoe if its a brand new battery?
Probably need a new alternator, or you battery cables or conectors could be bad If the battery is connected to your vehicle and it is not maintaining charge while the vehicle is running then it is more than likely your alternator that is out. If the battery does not have juice and is brand new then it is defective. I have also heard that if you place a car battery directly on concrete for a long period of time it will ruin. Always put a battery on a wood or a metal surface when storing.
What could be the problem if my 2000 Mazda miata has a new battery and the battery loses it's charge after driving the car in one day?
Check charging system with a voltmeter: Fully charged 12.8 without engine running 13.8-14.2 with engine running
How do you know if you need a battery?
Age of battery Battery will not hold a charge (check with a volt meter) A fully charged battery should read approx. 12.8 volts (without engine running) If charging system is working properly reading should increase to approx. 13.8-14.2 with engine running. If voltage does not increase with engine running could be a problem with charging system of battery is defective and will not take or hold a charge
When you drive your 2000 elantra you notice that smoke comes out of the battery top vent you changed the battery and this is still going on does anyone know what could be the problem?
The alternator is probably over-charging the battery. Replace the alternator if the voltage at the battery terminals is over 15V when the engine is running.
Why is your car jerking and running slow?
Your car battery could be running low so what you could do is get jumpleeds and get an other and jumpwire it
You have a brand new battery it discharges right after it is charged again is it the alternator?
Assuming the new battery is good! The usual problem why a battery is not charging is the alternator. The battery will be discharged if the alternator is not working properly when you start the engine and when the engine is running, etc. The vehicle uses the batteries electricity instead of the alternators electrical output, and of course if the battery is not being replenished by the alternator the battery will fail in a short period of time. You should test the alternator to see if it is putting out between 12 and 15 volts. Another possible things that could be the problem with a New battery failing so quick is, maybe the proper amount of acid was not put into the battery, a short in the wiring, etc.
Could a dead or dying airbag backup battery drain a main battery when the car is not running?
It might

If the alternator is installed incorrectly, yes, it can drain the battery.
