Car Battery Won’t Hold a Charge – Inspection & Repair in Hamilton

Why won’t the car battery hold a charge?

Car alternator

The alternator is the main part of your car’s charging system.

Nothing is more frustrating than a flat car battery, especially if the problem is continuously happening. A flat battery will prevent your car from starting until the battery is jump-started. However, a battery that won’t hold a charge will quickly run flat after jump-starting, making the jump-starting process futile. There are several different reasons a battery can hold a charge. These include:

  • Electrical current not reaching the battery.
  • Problems with the terminals, cables and wiring.
  • A battery due for replacement.
  • A malfunctioning part of your battery’s charging system.

How does your car battery’s charging system work?


Causes of the car battery not holding a charge:

Battery due for replacement – Car batteries have a limited lifespan. If the battery is very old, it can lose its ability to hold a charge. Car batteries should generally be replaced every 3-5 years.

Faulty alternator – The alternator is a key component in your car’s charging system. It provides the battery with electrical power and charges the car battery while your car’s engine is running. If the alternator encounters a problem, it may prevent your car’s battery from charging properly. 

Faulty alternator components – Loose or stretched belts and damaged alternator belt tensioners can prevent an alternator from working correctly. This can starve your car’s battery of energy and cause your car not to start. 

Damage to battery terminals or wiring – The battery is linked to the rest of your vehicle via terminals and cables. These components can become damaged due to corrosion, limiting the flow of power to and from the battery.
