How To Fix Your Dodge Charger Battery Keeps Dying?

A battery is an integral part of a car.Dodge Charger has a 12V battery that keeps the entire electrical system functioning. But recently, the Dodge Charger battery dying problem has become a headache for many users.

There are several reasons why the Dodge Charger battery keeps dying, such as a faulty alternator, corroded terminals, parasitic drains, extreme temperatures, or a defective battery.

Don’t worry if you have the same issues. In this article, I have described the possible causes, symptoms, and solutions to why is your Dodge Charger battery keeps drain so fast?

Causes of Dead Car Battery in Dodge Charger

Different problems can cause your car battery to die. However, if your Charger battery keeps dying, one of the following factors could be to blame:

01. Faulty Alternator

The primary responsibility of an alternator is to convert the engine’s mechanical energy into electricity and charge the battery. But when the alternator fails, the Dodge Charger battery cannot be charged while driving and seems dead.

Therefore, if your Dodge Charger battery keeps dying, check the alternator first. Sometimes, the alternator’s serpentine belt is responsible for the battery not charging properly.

A worn or damaged serpentine belt cannot move the alternator properly. That’s why the alternator fails to supply electricity adequately.

02. Damaged or Wrong Battery Charger

A proper battery charger is necessary to charge the battery properly. If you change your Dodge Charger battery, ensure that you take an appropriate battery charger.

An incompatible battery charger cannot charge your car properly, and the battery will keep dying. You can consult your dealer to select a compatible battery for your Dodge Charger.

03. Faulty Battery Connection

The car battery might be fine, but faulty battery terminals won’t let electricity flow as it should. As a result, the Dodge Charger battery acts like it is dying.

Battery terminal corrosion is the main reason for an inadequate electric supply. The problem may appear after 25 months or more than 02 years of battery installation. The faulty ground connection is also responsible for the battery problem.

04. Extreme Temperatures

If you continue driving in extremely hot or cold temperatures, it may reduce your car battery life. An old battery can lose its charge-holding capacity in hot or cold weather and drain continuously.

Try to avoid extreme temperatures and keep your Dodge Charger in the shade or low temperatures to keep your car battery healthy.

05. Parasitic Battery Drains

When the car battery continues to drain electric current even after the ignition is turned off, it is called parasitic battery drain. The parasitic draw continues to drain the car’s battery after parking the car.

You can inspect the parasitic draw using a multimeter or ask a mechanic for assistance. Parasitic draw is one of the reasons the battery keeps dying, but it’s a rare case.

06. Expired Battery

Sometimes the problem is with the battery itself. If the battery warning light appears while driving, it indicates a problem with the alternator. But if the battery isn’t responding or seems dead when you try to start your vehicle, the problem may lie with the battery.

An expired battery can sometimes cause a Dodge Charger to die. So, take your car to a mechanic to diagnose the battery and check it properly when you buy a new one.

Symptoms of Charger Car Battery Keeps Draining

When the car battery keeps draining, the driver can often be observed it. However, some early signs can help identify a failing battery.

The signs are:

  1. Delay engine start
  2. Check engine light pops on
  3. The headlights are DIM
  4. Battery terminals are corroded
  5. Electrical problems
  6. The Charger engine cranks, but it won’t start
  7. You may notice a rotten egg smell after opening the car hood, etc.

Solution for Dodge Charger Battery Keeps Dying

The first step is to diagnose the problem causing the Dodge Charger battery to keep dying. Sometimes, a car battery dies because of a faulty alternator, damaged cable connections, or corroded terminals.

You must test the parts to identify which one is faulty. After finding the faulty part, you can easily resolve the Dodge Charger battery issue.

How to Test Alternator in Dodge Charger?

The easiest way of testing the alternator is by checking the battery voltage.

Follow the steps to test your Dodge Chargers’ alternator:

  1. Open the car hood and use a multimeter to check the battery voltage
  2. Ensure that the car and engine are off before using the multimeter
  3. Attach the multimeter’s red terminal to the battery’s positive side and the black terminal to the negative side.
  4. Now check the battery voltage when the engine is turned off.
  5. The voltage should be between 12 and 13 volts.
  6. Now start the engine, and after a minute, check the voltage again
  7. The voltage should increase and rise by about 13.2 to 14.2 volts.

The alternator can’t produce enough voltage if the voltage stays the same or decreases. Check the serpentine belt of alternator. If it is damaged or worn out, replace it with a new one.

The problem should be solved. If the alternator still doesn’t produce enough voltage, take the vehicle to a repair shop and change the alternator with a new one. It will resolve the issue with your Dodge Charger battery dying.

Test for Parasitic Draw in Dodge Charger

The main reason why car batteries keep dying is the parasitic draw. So, it is critical to test for parasitic draw. This test can help you determine which part is causing the problem. To perform the test, watch the video.

How to Clean Battery Terminals?

A corroded battery fails to pass electricity through the terminal properly. As a result, the electrical system cannot get the power it needs to function properly. Therefore, cleaning the corrosion is crucial to keeping the battery working optimally.

Follow these 09 steps to clean corrosion from the battery terminals:

  1. Make a homemade battery cleaner solution using water and baking soda
  2. Put an old toothbrush into the solution and clean the terminals using the brush
  3. Use a clean towel to dry the battery and towel
  4. Remove the negative terminal and then the positive terminal
  5. Inspect each terminal and cable properly; if there is any damage, replace it.
  6. Use a battery brush to clean the terminals inside the circle area.
  7. Put the open head of the battery brush on the battery posts and rotate it for a few minutes to clean each post properly.
  8. Now use a towel with baking soda and clean the battery’s outside
  9. Reconnect the battery cables.

After applying this method, the battery dying issue with your Dodge Charger should be resolved.

Always remember that regular battery maintenance is essential to keeping the battery healthy.

Replace the Dead Battery

After trying all the above solutions, if the problem is still there or the battery is old enough, you must replace it.

Flow the steps below to replace the Dodge Charger battery:

  1. Disconnect the negative cable first, then the positive cable
  2. Pull out the attached bolts
  3. Disconnect all terminals and remove the old battery
  4. Clean the base area and place the newly purchased battery
  5. Reassemble all the bolts and terminals with the new battery
  6. Now connect the cable to the positive terminal first and then the negative terminal of the battery
  7. You can use silicone grease on the battery terminals to prevent corrosion.

These are all ways to resolve the problem of the charger’s battery dying.
