How Often Should a Vehicle's Battery Be Replaced?
1 Answers
An automotive battery typically needs to be replaced every 3 to 5 years. When the battery's voltage and internal resistance no longer meet the specified standards, it should be replaced promptly. The car battery is an essential component of a vehicle. Due to the use of lead-calcium alloy for the grid framework, it generates minimal water decomposition during charging and has low water evaporation. Additionally, the sealed structure of the battery case releases very little sulfuric acid gas, offering advantages such as no need for liquid replenishment and long-term power storage. Functions of an Automotive Battery: 1. Provides a strong starting current to the starter when igniting the engine. 2. Assists the generator in supplying power to electrical devices when the generator is overloaded. 3. Supplies power to electrical devices when the engine is idling. 4. Acts as a high-capacity capacitor to protect the vehicle's electrical appliances. 5. Converts part of the electrical energy into chemical energy for storage when the generator's terminal voltage exceeds the battery's electromotive force, facilitating recharging. The lifespan of a battery is generally 2 to 4 years, but this can vary depending on seasonal factors, the vehicle's mileage, and regional differences. Batteries in southern regions tend to last longer than those in northern regions. For example, a vehicle driven 10,000 kilometers per year versus one driven 50,000 kilometers per year will experience significantly different battery consumption and lifespan impacts. Higher mileage means more frequent battery usage, thereby shortening its service life.
