Question about Chevrolet Impala
Has new battery alt. charging
If the battery goes dead in a few days, something is "on" and draining it.
Someone will need to check the circuits to find the drain. You can pull all of the fuses or check each circuit one at a time with a test light.

I assume you have replaced the battery? If not have it tested.
Check to see if a glove box light, trunk light or under hood light is staying on. Also you can remove the negative battery cable and then reinstall it. When reinstalling it, if you see a spark (other than just a very small one) there is a current draw on the battery. This current draw can be isolated by pulling one fuse at a time to see when the battery stops sparking on reconnect. It is possible you could have a shorted voltage regulator causing the current draw also. Many things can cause this problem.

Have the computer checked. On your vehicle the computer is what tells the alternator to turn on to start charging. If the alterantaor is not getting that signal from the computer you will have to replace the computer.

Get a multimeter then disconnect the positive side of the battery. Measure the amp(current) between the terminal you just disconnected and the positive battery while the car is off. and have someone get a tweezer and pull out one at a time each fuse in the fuse box. When the amp goes down on the multimeter then you found out where in your car there is a short. Note the fuse you pulled out in your car manual. It could be radio shorting, domelight shorting. Sometimes kids drop pennys or coins in the radio disk slots shorting the radio or amplifier in the car is always on.
