Why isn’t my new vehicle’s battery charging?

What is the matter after all?

If you jumpstart a car battery and it doesn’t start, it’s likely something other than the battery.

This means that your car battery is not capable of maintaining a charge. But why is it so? Several reasons could be responsible for your dead battery.

So, why is your battery not charging?

Alternator Failure

When the alternator in your vehicle is bad, the battery will be low on charge or dead. A low-charged battery has less capacity and starting power than a fully-charged battery. Constantly undercharging the alternator will kill the battery.

Battery Consumption

Most vehicle accessories including interior lights, GPS, radio, and Bluetooth kit turn off when the engine is turned off. If they are not turned off properly, they can drain the battery.

Some devices may require a live connection to maintain specific settings, resulting in unexpected battery drain.

Faulty Electrical Control Unit (ECU)

Errors in the ECU can result in symptoms such as engine stall or the check engine light coming on.

There could be a problem with the charging system as the ECU controls all the electrical systems of the car.

Extreme Temperature

Heat is the most prevalent cause of battery failure. The heat induces grid corrosion and grid development on the positive plate. The battery loses capacity when heat corrodes the positive wire, making it less capable of starting the engine.

Faulty battery installation, as well as lack of maintenance

  • The battery is being used for a purpose other than the one for which it was designed.
  • There is an excessive amount of electrical equipment in the vehicle.
  • Battery cables have not been cleaned or adjusted to fit properly in battery terminals.
  • The vehicle’s electrical system has been repaired or replaced.
  • The vehicle remained in the warehouse for a long time.
  • Wiring problem
  • Vibration, while the engine is running, can cause the battery connections to loosen. On the other hand, a damaged or loose battery cable can interrupt electrical contact between the alternator and the battery.

Your vehicle has been standing for a long time

Sometimes a battery will lose its charge if neglected for too long. Make sure to start your vehicle from time to time and drive the car around you to charge the battery.

The battery is either too old or dead.

A lead-acid battery in a vehicle lasts for 3-4 years. A battery that is too old or damaged can bulge, crack, and spew battery acid, or corrosion. Corrosion on battery terminals compromises electrical connections and charging capabilities. Sulfation, which corrodes the inner plates of a battery cell, can affect older batteries as well.
