How Long Does a New Car Battery Last?

[DeJackson]

Generally, a car battery can last for 4 years without issues. However, if the owner has poor driving habits, the battery may need replacement after about 3 years. Below are some key points about car batteries: 1. When replacing the battery, always remove the negative terminal first, followed by the positive terminal. The battery is a crucial component of a car and a wearable part that requires periodic replacement. When the engine is off, the battery powers all electronic devices in the vehicle. Once the engine is started, the alternator takes over to power the electronics and also charges the battery. Avoid sitting in the car for extended periods with the engine off while using electronic devices, as this can shorten the battery's lifespan. 2. Prolonged exposure to low temperatures can also negatively impact the battery's lifespan. To extend the battery's life, drivers should avoid poor usage habits. When replacing the battery, consider opting for an AGM battery, which has a longer lifespan and better charge/discharge performance compared to standard batteries. Additionally, avoid turning on power-intensive systems like headlights or air conditioning before starting the engine during regular use.
