Car batteries play a very important role in starting the car and getting you on the road. But do you have sufficient knowledge about your car’s battery? What if you get stuck in the middle of the road? Thus, the time has come that you to get familiar with your car battery’s ins and outs to get an insight into car battery maintenance and troubleshooting. Take part in an adventure to learn how to maintain a healthy car battery. We’ll go over the fundamentals of battery care, show you how to recognize warning signals of a failing battery and teach you basic troubleshooting procedures to keep you from becoming trapped in challenging locations. As we shine a light on the often ignored area of car battery maintenance, prepare to become a battery guru. 

How to maintain car’s battery?

  • Regularly Inspect and Clean Battery Terminals: The battery terminals might corrode with time, affecting the battery’s performance. Look for white or greenish deposits on the terminals to check for corrosion. If you find any, clean them with a baking soda and water mixture. Scrub the terminals gently with a wire brush, then tighten them securely after cleaning.
  • Check and Maintain Proper Fluid Levels (if applicable): Removable caps on some car batteries give access to the battery cells. It’s essential to regularly monitor the fluid levels inside these cells, particularly in non-sealed batteries. If the levels are too low, gradually add distilled water to raise them up to a suitable level. Just be careful not to overfill the cells.
  • Test the Battery and Charging System: For detecting the issues related to the battery early and also the ensure that both the systems are working efficiently,  it is important to regularly check the battery voltage and charging system performance. Make use of a multimeter to check the voltage of the battery or it can be tested by an experienced technician. Verifying the functionality of the charging system is important to make sure that the alternator is effectively charging the battery.
  • Keep the Battery Secure and Clean: Make sure the battery is properly mounted in its tray to prevent excessive vibrations that may harm the battery.  It is also important to maintain the battery clean. Check for dirt and debris, as they can cause electrical leakage and corrosion. To clean the battery, use a wet cloth or a gentle brush.
  • Avoid Excessive Electrical Drain: It’s a good idea to reduce unneeded electrical drains to extend the life of your battery. To keep the battery from draining, switch off music systems, lights, and other accessories when not in use. Leaving these electrical components active for prolonged durations can lead to battery drain and a reduction in the overall lifespan of the battery.

Car Battery Troubleshoot

Troubleshooting car battery issues is all about detecting and resolving problems that may impact its performance and functionality.

  • Slow or Difficult Engine Start: When you experience a sluggish or challenging engine start, it could be a sign of a weakened battery or other battery-related problems. To investigate further, you can employ a multimeter to measure the voltage across the battery terminals. A fully charged battery typically reads around 12.6 volts. If the voltage significantly drops below this level, it suggests a weak or discharged battery that might require recharging or replacement.
  • Dead Battery: Dealing with a dead battery can leave you stranded, with no response when attempting to start your vehicle. In such circumstances, you can try jump-starting the battery using jumper cables and another vehicle that has a fully charged battery. It is crucial to follow the correct procedures and prioritize safety during this process. After jump-starting, it becomes important to address the underlying cause of the battery drain, which may involve investigating a faulty alternator or electrical component.
  • Corrosion on Battery Terminals: The presence of corrosion buildup on battery terminals can impede the flow of electricity and impact battery performance. To check for corrosion, inspect the terminals for any white or greenish deposits. If you spot corrosion, you can clean the terminals using a mixture of baking soda and water. Gently scrub the terminals with a wire brush, ensuring that the battery is disconnected during the cleaning process. Once cleaned, applying a protective terminal spray or grease can help prevent future corrosion.
  • Alternator Issues: The alternator plays a critical role in charging the battery while the engine is running. If you find that the battery continues to drain even after jump-starting or replacing it, it could indicate a malfunctioning alternator. In such cases, seeking professional assistance is advisable to diagnose and address any underlying alternator-related problems. It is possible that a faulty alternator may require repair or replacement to ensure the battery receives a proper charge.


Check the positive and negative terminals as part of your automobile battery repair routine wherever it is connected to the wiring. Corrosion is indicated by greenish-white goo. You must tidy things up. There is usually no danger because this happens with various types of automotive batteries as they age.

In case of corrosion on the battery terminals, especially if it reoccurs shortly after cleaning or with a new battery, it indicates an underlying car battery care issue that requires attention.

Typically, most car batteries have a charge of 12 Volts, although the specific voltage may vary depending on the brand and model of your vehicle. To determine the battery charge and proactively address any potential car battery maintenance issues, you can visit a garage or utilize a volt tester. Taking these proactive steps will help ensure the proper functioning of your car battery.

Never forget that your vehicle’s battery is its pulse, thus frequent monitoring and car battery maintenance are crucial for both your peace of mind and the continued health of your vehicle.
