Fixing a Car Battery That Doesn’t Hold a Charge

Car batteries are crucial for a vehicle’s functionality, powering the engine and electrical systems. However, as time passes, these batteries can lose their ability to hold a charge efficiently. If you’re grappling with a dead battery that doesn’t hold a charge, don’t despair – there are solutions. In this guide, we’ll discuss common issues causing this problem and practical steps to rectify it.

Diagnosing the Problem 

Before jumping into solutions, let’s grasp why your car battery may fail to retain a charge:

  • Sulfation:

    Sulfate crystals building up on a battery’s plates can impede its ability to hold a charge. Regular maintenance like checking electrolyte levels and keeping the battery clean, can often rectify this problem. Preventing sulfate buildup through proper care ensures your battery functions effectively and lasts longer.

  • Low Electrolyte Levels:

    Regular maintenance of batteries with removable caps is crucial. These batteries need routine checks to ensure their electrolyte levels remain at the recommended levels. Inadequate electrolyte levels can significantly affect battery performance, potentially leading to issues with charging and overall battery lifespan.

  • Age and Wear:

    Car batteries typically last between 3 to 5 years. Beyond this lifespan, they can become less reliable and prone to failure. If your car battery is older, it’s advisable to consider a replacement to avoid unexpected breakdowns. Regularly checking and maintaining your battery can help maximize its longevity within this timeframe.

  • Parasitic Drain:

    Battery drainage occurs when certain electrical components in a vehicle continue to draw power when the engine is off. This can be due to issues like faulty wiring or leaving devices switched on. Identifying and addressing these problems is essential to prevent unnecessary battery drain and ensure your car starts reliably.

How to Revive a Dead Battery? 

  • Visual Inspection:

    Begin your car battery maintenance with a visual check. Look for corrosion on the battery terminals or any visible damage. If you find corrosion, clean the terminals, and if there’s damage, consider replacing the affected components to ensure your battery functions optimally.

  • Charge the Battery:

    Recharge the battery with a charger if it’s not entirely dead. This can break down sulfate crystals and improve battery performance. Look for a professional to help you charge the battery. This process involves applying controlled voltage bursts to the battery, effectively reversing sulfation and extending its life.

  • Test the Alternator:

    Ensure the alternator is functioning correctly by using a voltmeter to verify if it’s charging the battery as it should.

  • Address Parasitic Drains:

    Identify and repair components causing parasitic drains by disconnecting them one by one.

  • Battery Reconditioning:

    Some products claim to recondition old batteries by breaking down sulfate crystals, potentially extending battery life.

  • Battery Replacement:

    If your battery is old and none of the above step’s work, replacing it may be the most cost-effective solution.

Preventive Measures

To prolong your car battery’s life and prevent charge-holding issues, consider these preventive measures:

  • Regular Maintenance:

    Keep your battery clean and maintain proper electrolyte levels.

  • Turn Off Electrical Accessories:

    Ensure all electrical accessories are off when the car is not used to prevent parasitic drains.

  • Properly Store Your Vehicle:

    If your car won’t be used for an extended period, disconnect the battery . Turn the ignition of the car on at regular intervals to keep the battery charged.

  • Replace Old Batteries Promptly:

    Don’t wait for total failure; replace old batteries with the help of Carfit Experts.


A car battery losing its charge-holding capacity can be addressed with proper diagnosis and steps to rectify the issue. However, replacing a dead battery is often the most practical solution to ensure your vehicle remains reliable when severely damaged or old.

Remember, maintaining your car battery and adopting preventive measures can go a long way in preventing future issues and extending the life of your battery. Contact Carfit Experts for top-notch car battery service.
