The normal service life of a car battery varies from 1 to 8 years, largely depending on the condition of the vehicle. If the vehicle's alternator charges properly and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years. Battery maintenance methods include: 1. Avoid parking the car in open parking lots for extended periods; 2. In winter, when the car engine is difficult to start, each attempt should not exceed 5 seconds, with a minimum interval of 15 seconds between attempts; 3. The car battery should be charged regularly. If left unused for a long time, it will gradually self-discharge and eventually become unusable, so the car should be started periodically to recharge the battery; 4. Clean the battery terminals regularly and apply special grease to protect the wiring harness.

How to Lock the Doors of a BMW?

Some BMW models come with an automatic door locking feature, which can be activated in the iDrive system to automatically lock the doors while driving. Alternatively, you can use the smart key to lock the doors after parking. Below is an introduction to the automatic door locking function: 1. When the vehicle reaches a preset speed, the door lock buttons will automatically engage to prevent accidental opening of the doors. The preset speed is usually set by the manufacturer, typically between 10-20 km/h. 2. This function can be used for anti-theft purposes, as the doors lock shortly after driving begins, preventing potential theft during traffic jams or at red lights. 3. It also provides protection for children inside the vehicle by preventing them from opening the doors while the car is in motion.

What are the reasons why a smart car cannot start?

It is due to a depleted battery. Below is the relevant introduction: Battery: A battery is a type of cell, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Misconceptions: When the liquid level is low, people often replenish it with electrolyte or drinking purified water instead of the required distilled water. Adding electrolyte containing sulfuric acid will increase the concentration of the electrolyte inside the battery, leading to phenomena such as boiling and acid mist, severely affecting the battery's lifespan. Using drinking purified water instead of distilled water is also problematic, as purified water contains various trace elements that can adversely affect the battery.

Will carrying 500 jin (250 kg) of cargo damage an SUV?

Carrying 500 jin (250 kg) of cargo in an SUV can damage the vehicle. Below are the hazards of overloading: Braking performance: Vehicle load directly affects braking distance, which is a critical factor in stopping performance. Due to increased inertia, overloaded vehicles require longer braking distances. The expanded danger zone between vehicles can easily lead to traffic accidents. If the weight is concentrated in the trunk area, the rear of the vehicle will sag downward, affecting driving dynamics. This is particularly dangerous during uphill, downhill, and turning maneuvers, where loss of control becomes more likely. Leaf spring usage: Overloading the drivetrain and leaf springs causes continuous rebound during operation, significantly shortening the springs' service life.
