Car batteries typically have a lifespan of 2 to 4 years. Here are more details about car battery lifespan: 1. Regular car batteries use lead-acid technology with a cycle life of approximately 200 to 500 charges. 2. Vehicles equipped with auto start-stop systems use specialized batteries that offer higher cycle life (400-800 charges) and longer service life (4-6 years). 3. New energy vehicles use lithium batteries which have the longest lifespan, lasting 5 to 8 years. Extended information: Methods to prolong battery life include avoiding using in-car devices or external power sources when the engine is off; always turning off headlights when parking overnight; performing battery checks every six months; and disconnecting all in-car electronic devices from the battery when the vehicle won't be used for extended periods.

What does the steering system include?

Steering system consists of three major parts: steering control mechanism, steering gear and steering transmission mechanism. The following is the relevant introduction of steering system: 1. Construction principle: The power steering system is a steering system that uses both the driver's physical strength and the engine power as the steering energy source. Under normal circumstances, only a small part of the energy required for car steering is provided by the driver, and most of it is provided by the engine through the power steering device. However, when the power steering device fails, the driver generally still independently undertakes the task of car steering. 2. Definition: Modern mid-to-high-end cars and heavy-duty vehicles generally adopt power steering systems, which not only greatly improves the ease of car operation but also enhances driving safety.
