How Long Does the Original Battery Last?
2 Answers
The original battery can last for 4 years. When the load voltage drops below 10V or you experience difficulties in starting, lack of power during acceleration, or dimming of lights, it is important to replace the battery promptly. The functions of a car battery are: 1. To supply power to the starting system, ignition system, electronic fuel injection system, and other electrical components of the car; 2. To provide power to the car's electrical equipment when the engine is off or idling at low speed. Battery maintenance should include: 1. Developing good electrical habits in the car, such as avoiding listening to music when the car is turned off and not using the car's power source to connect high-power appliances like refrigerators, vacuum cleaners, or air pumps; 2. Disconnecting the battery cable if the car is not used for a long time, as the battery can still discharge over time, leading to battery degradation.
I've replaced the battery several times. The original one usually lasts three to five years, depending on how you use the car. In the cold winters up north, the battery in my first car only lasted two and a half years because low temperatures have a big impact. If the car is frequently exposed to intense sunlight in summer, the battery's lifespan can also shorten. If you often drive short distances without giving the battery a chance to fully charge, or if the car sits unused for too long, the battery can easily die. I recommend checking the battery voltage every year, especially after two or three years of use—it's best to replace it early to avoid being stranded when you can't start the car. On the other hand, although original batteries are more expensive, their quality is usually more reliable. For example, my friend's family car easily lasted four and a half years with its original battery. The key is regular vehicle maintenance.
