Why might a battery not hold a charge after replacing the battery and having the alternator tested?

check for a drain on the battery. It sounds like something is drawing power from the battery all the time. Also make sure your connections are tight and clean. A lose ground wire will drain it instantly.

How can you get your battery to charge with out the charger?
You cannot charge a battery without a battery charger or having it charged by the alternator in your vehicle while it is running.
2000 Astra 1.7DTi Battery warning light is always on since I replaced a faulty Alternator. I've fitted a new drive belt and battery since and its still on. Any Ideas?
I'm having the same problem. The cause of the nackered battery and dead alternator could be a faulty charge relay. Try replacing this and see if the light goes out..
What to do if the computer screen remains black after replacing the battery?
The obvious answer (without having any additional information) would be to charge the battery !
Where is the voltage regulator located on a 1984 Nissan Sentra?
It is part of the alternator. If you are having problems keeping a charge or problem with high voltage, you might want to consider replacing your entire alternator.
What would make the battery in a 1999 Chevy prism not hold a charge?
check the alternator for most cars the alternator is wat powers the car the battery is for accesories... a quick check for alternator wit out having to disemble it tunr on ur car disconnect the postitive cable on the battery if car stays on then the alternator is good and the actual battery itself might be bad
Can a loose positive battery cable prevent the alternator from charging the batter and can it cause a battery drain while the engine is not running?
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
Why would the battery in a VW Jetta not be getting any charge if it has been replaced but you still have the same problem?
You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
What are the symptoms of car alternator problems?
Symptoms: Besides having a dead battery.......... If you charge or jumpstart your vehice's battery and successfully get it running to only have it mysteriously die and have no lights, radio, etc.; it is probably you alternator. If your vehicle will run constantly on it's own, but will not start after shutting it off, it could be your battery. If your battery will hold a charge on it's own, but goes dead a while after you start and run your vehicle, it is probably your alternator. Or, if you can get it running, it should have an alternator light that will come on when there is a problem. I would almost bet your car has one... my 1970 ford does.
When it it very cold the voltage meter on the dash board is low and have a herd time to start and when it start rpm is low and engine stop after releasing gas pedal?
Cold does that to car batteries and (some) engines. You might consider replacing the battery, or if the battery is still fairly new, consider having the alternator and charge relay checked out.
Why does the battery light come on a 1996 Ford Exployer after changing the battery and having the alternator checked?
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
How do you know if the battery is no good on a 2000 ml320?
Should really charge it then test it with a proper battery load tester. All you can do on your own is get a multimeter and check the voltage. Without it running and having sat for a 1/2 hour or so the voltage should be approx 12-12.5 volts. Start the engine and if the alternator is good the voltage at the battery terminals should be 13-14 volts. If without the engine running the battery voltage is 12 or less this may indicate that the battery is not holding a charge. Even then the voltage should go to between 13-14 volts when engine is started showing that the alternator is working to charge the battery. If when started the battery voltage stays around 12-12.5 volts or less I would suspect the alternator. Just to double check there is the main power out terminal on the back of the alternator. With the engine running check the voltage. If 13-14 volts is present at the alternator but not the battery the circuit in between the alternator and battery is suspect. If the voltage at the alternator is the same as at the battery (12-12.5 or less) the alternator or voltage regulator may be defective.
2007 Chevy Equinox battery won't stay charged and has a new alternator and a new battery but still won't hold a charge what else could it be?
did you find the problem?? i having the same deal with my '06. new battery and alt is fine!
