The 2007 Chevy Impala is a four-door sedan that was sold with four different trim lines. All Impalas came with a battery run-down protection system to prevent you from being left stranded with a dead battery. In the event you leave the headlights or interior lights on when you turn off the vehicle, they will automatically shut off after 10 minutes. However, there are many other reasons you could be left with a dead battery, including the most common one---an old battery at the end of it's life. Other reasons could be a bad alternator or an electrical malfunction. Whatever the reason, changing the battery is simple and only requires a few steps.

[edit] Change the Battery

  • Turn the ignition into the off position and remove the key.
  • Pop the hood and locate the battery on your 2007 Chevy Impala. It is in the front of the vehicle, directly behind the passenger's side headlight.
  • Disconnect the negative battery clamp by using the wrench to loosen the bolt on the clamp. Once the bolt is loosened, twist and pull up on the clamp to remove it from the battery terminal.
  • Disconnect the positive battery clamp in the same manner you used to disconnect the negative clamp.
  • Loosen the bolt that is securing the clamp that holds the battery in place. Remove this clamp and lift the battery out of the engine compartment.
  • Mix the baking soda and water in cup so that it forms a paste-like consistency. Dip the wire brush into the mixture and scrub the clamps at the end of the battery cables to remove any corrosion on the clamps. This will help ensure you get a good, strong connection with the new battery. After you've scrubbed them, wipe the clamps with a clean towel.
  • Place the new battery into the engine compartment of your 2007 Chevy Impala. Be careful not to drop it too quickly, which can crack the battery and damage it. Replace the clamp holding down the battery and tighten the bolt.
  • Attach the positive battery clamp to the positive battery terminal and tighten it with the adjustable wrench. Attach the negative battery clamp on the negative battery terminal and tighten it as well.
  • Start the vehicle and confirm everything is working as it should.

[edit] Tips & Warnings

  • If you are not going to be driving your 2007 Chevy Impala for more than 25 days, disconnect the negative battery cable from the battery to prevent the battery from slowly discharging.
  • There are many different brands of replacement batteries from which to choose. By giving your car's year, make and model to an auto parts store representative, he can show you all of the various batteries you can choose for your Impala. The prices of the batteries are heavily influenced by the length of warranty that accompanies them.
  • After you replace the battery in your Impala, you'll need to reprogram your stereo presets and the clock, as these settings will have been wiped out when you disconnected the battery.
  • Always return the used battery to the store where you bought the new battery. This will ensure the battery is properly recycled. Used car batteries should never be thrown in the trash because they contain toxic chemicals.
  • Always be sure you know the difference between the positive and negative terminals and clamps. The positive ones are marked with a plus sign and the negative ones are marked with minus sign. Improperly connecting the battery cables will cause a spark and electrical short.
