- Cold weather is the only cause of battery failure.
- Leaving lights on always kills the battery.
- Battery maintenance is unnecessary for newer cars.
Understanding these myths is crucial for proper car battery care and longevity. Let’s take a closer look at each myth to clarify the facts.
-
Car batteries only power the starter motor: This myth is misleading. Car batteries not only start the engine but also power electrical systems when the engine is off. They run headlights, radios, and air conditioning. According to a study from the Society of Automotive Engineers (SAE), battery capacity is critical for a vehicle’s entire electrical system to function effectively.
-
All car batteries are the same: This assertion is incorrect. Car batteries vary significantly in size, capacity, and type. Common types include lead-acid and AGM (Absorbent Glass Mat) batteries. The AAIA (Automotive Aftermarket Industry Association) warns that using the wrong battery type may damage vehicles or impair performance.
-
You should always jump-start a dead battery: This is a common misconception. While jump-starting can help, it is essential first to determine the condition of the battery. Some batteries may be damaged beyond recovery and jumping them could lead to further issues or hazards. A battery test is advised before proceeding with a jump-start.

Cold weather is the only cause of battery failure: This is an oversimplification. Extreme heat can also damage car batteries. High temperatures can increase the rate of battery fluid evaporation, leading to reduced lifespan. The Battery Council International indicates that batteries are most vulnerable at both extremes of temperature.
-
Leaving lights on always kills the battery: While leaving lights on can drain the battery, it’s not the only factor. Components such as interior lights, GPS devices, and even a malfunctioning alternator can contribute to battery depletion. An example is a car parked for an extended period with electronic devices left on, leading to slow discharge over time.
-
Battery maintenance is unnecessary for newer cars: This myth can lead to premature battery failure. Newer cars often have advanced electrical systems that rely on healthy batteries. Regular battery maintenance, including terminal cleaning and testing for charge levels, is recommended by the Battery Maintenance Institute.
Addressing these myths empowers car owners to maintain their vehicles better and avoid unnecessary repairs.
