Dead cell in the battery requiring a replacement battery or some light is on that is draining the battery. Can also be a stuck relay.
An alternator keeps the battery charged in a vehicle. In a 2006 Chevrolet Impala when the alternator fails the battery will keep dying and no power will be available when attempting to start the car.
It means your alternator (generator) is not charging the battery while the engine is running.
To test the alternator if funds are low, let the motor idle and remove the negative battery cable, if the motor dies its probably the alternator.
it indicates that the alternator is not functioning sufficiently to keep the battery charged.
AC Delco 78DT6YR seems appropriate for your car...
There are a couple of things that can drain the battery on your impala. If you have a new battery and it is dead overnight and you have to jump start it, check your positive and negative cables to be sure they are secured properly and not loose at any connection point. You might also have a short in your wiring that is not alowing the power to be turned off to a sourse, ie. a speaker, the radio, any thing such as an electornic compass, thermometor, or dome light. Also if you have an auto start on your vehicle try turning the switch to an off position when you turn off the car. If that fixes it. take it back to the installer and have them fix their install.

Chevrolet Impala was created in 1958.
if its a new battery then you need to replace your alternator. It basically recharges your battery while the vehicle is running.

It is the black cable on the battery. All GM ground wires are black.
