Have you ever experienced difficulties starting your car?
A potential cause of this issue could be a weak or dead battery. To check if the battery is weak, you can use a battery tester that measures cranking amps. If you don’t have access to a tester, try jump-starting the car. If it starts up easily, then a dead battery was the most likely culprit. Charge the battery and clean the terminals and cable connectors to ensure proper contact. However, if the jump-start doesn’t work, you may have a problem with your starter, alternator, or another component of the electrical system. It is important to follow all safety and handling instructions when working with batteries.
There are several common causes of car battery failure. High temperatures are the number one cause of battery failure, as heat accelerates grid corrosion and growth in the positive plate. This results in the battery losing capacity and starting power, particularly in colder weather. Vibration can also cause damage and separation of internal components, leading to reduced starting performance or battery failure. Deep drains or failure to recharge after voltage drops can result in discharged material and the formation of larger, harder-to-dissolve lead sulfate crystals, ultimately disrupting the plate structure and leading to battery failure. A faulty alternator can also cause undercharging or complete discharge of the battery, which reduces its capacity and starting power, and can lead to sulfation.
Possible Causes of Car Battery Failure:
Battery Application and Installation
Using an SLI (Starting-Lighting-Ignition) battery in a vehicle that requires a deep-cycle battery is a common mistake that can cause battery failure. Another possible cause is when the battery is not sized properly for the application or when the vehicle has too many electrical accessories. It is also important to ensure that the battery is properly installed.
Service and Maintenance
Failure to clean and properly adjust the battery cables to fit the battery terminals can cause battery failure. If the vehicle’s electrical system has been repaired or altered, it is important to make sure that the repair work was done properly. Additionally, if the vehicle has been in long-term storage, it is important to properly maintain the battery during that time.
Driving Style and Alternator Performance
If you mostly drive short trips several times a day, your alternator may not have enough time to recharge the battery fully after starting the car, leading to quick voltage drops that can cause battery failure. Factors that affect the alternator’s ability to adequately charge a battery include the amount of current diverted to the battery to charge, how long the current is available during drive time, battery temperature (cold climates require more time to charge), and battery age. If you don’t drive your vehicle far enough to let the alternator fully recharge the battery, use a battery charger to restore it to full capacity.
