How Long Does a Normal Electric Vehicle Battery Last?
1 Answers
Car batteries are consumable items with a limited lifespan and require replacement after a certain period of use. Typically, a car battery can last anywhere from 2 to 5 years, depending on the type of battery, usage conditions, and maintenance. With proper maintenance and good driving habits, the lifespan of a car battery can be extended to 4-5 years. Below are some relevant details: 1. Types of Batteries: Car batteries are categorized into maintenance-free batteries and conventional batteries (lead-acid batteries). Most modern vehicles use maintenance-free batteries, while many Japanese cars still use conventional batteries. Conventional batteries have electrodes made of lead and lead oxide, with an electrolyte of sulfuric acid solution, and generally last about 2 years, making replacement every two years ideal. Maintenance-free batteries are more durable, typically requiring replacement every 3 years. 2. Regular Maintenance: To extend the battery's lifespan, regular maintenance and good driving habits are essential. When the electrolyte level is low, the battery may fail to hold a charge, necessitating timely refilling. After turning off the engine, ensure all lights are switched off to prevent excessive battery drain. If the car is left unused for an extended period, it is advisable to disconnect the battery's negative terminal to avoid discharge. Additionally, starting the car once a week allows the battery to recharge via the internal alternator while the engine idles, ensuring sufficient charge for the next start.
