The voltage of a car battery during charging is generally between 14V and 15V; the current should be one-tenth of the battery capacity, typically around 0.7A. Below is more information about car batteries: 1. Lifespan: The normal lifespan of a battery ranges from 1 to 8 years, largely depending on the condition of the vehicle. If the vehicle's alternator recharges properly and there is no electrical leakage or grounding, the battery can generally last more than 3 years. 2. Maintenance: Avoid parking the car in an open-air parking lot for extended periods. If the car is to be parked for a long time, remove the battery to prevent it from freezing and getting damaged. Clean the battery terminals periodically and apply special grease to protect the wiring harness.

What are the differences between the 350Z and 370Z?

350Z and 370Z differ in engine displacement. Below is a detailed introduction to their differences: 1. Power: The 350Z is equipped with a 3.5L V6 engine, delivering a maximum power of 206KW (280HP) and a maximum torque of 363NM. Currently, the 350Z is only available with a 6-speed manual transmission. In contrast, the 370Z features a 3.7L V6 engine, producing a maximum power of 244KW (332HP) and a maximum torque of 366NM. 2. Materials: The new 370Z utilizes more lightweight materials. These modifications result in a lighter body weight, significantly enhancing the performance of the new 370Z in various aspects (acceleration, braking, and cornering).

Is a Fire Extinguisher Required for Vehicle Annual Inspection?

Vehicle annual inspection requires a fire extinguisher. Both the vehicle's fire extinguisher and warning triangle are essential items during the annual inspection. Some vehicles do not come equipped with a fire extinguisher when leaving the factory. Therefore, car owners should prepare one themselves for their own safety and to pass the annual inspection smoothly. Below is additional information: 1. Note: During the annual inspection, the vehicle management office will check the vehicle's lights. If the vehicle's lights are found to be too dim or too bright, it will be deemed unqualified and will not pass the annual inspection. Therefore, it is necessary to check the vehicle's lights in advance before the annual inspection. If the lights are too dim, check the light circuits and whether the bulbs are aged, and replace relevant parts if necessary. If xenon headlights have been installed, it is recommended to restore the original headlights before the annual inspection to pass the test. 2. Vehicle braking performance: The braking performance of a vehicle is one of the most important indicators of vehicle safety and is a mandatory inspection item during the annual inspection. Therefore, it is necessary to check the brake system in advance before the annual inspection. Brake fluid and brake pads are two key areas that need attention in the brake system. Dirty brake fluid or excessive water content can lead to soft brakes, and excessive wear of brake pads can result in reduced braking force and abnormal brake noise.

What is the Suitable Color Temperature for Xenon Lights?

4300K and 5000K color temperatures are more suitable. The advantages of automotive xenon lights are as follows: 1. Performance improvement: Under the stable operation of the ballast, the HID gas discharge headlight assembly only requires 35W of power to supply the xenon bulb for illumination, greatly reducing the burden on the vehicle's electrical system and correspondingly improving vehicle performance. 2. Brightness enhancement: High brightness ID lights can output up to 3200Lm, meaning the brightness of automotive xenon headlights is increased by 300%, illuminating brighter, wider, and farther, leaving no dark spots. 3. High comfort: The light emitted by ID lights with a color temperature of around 6000K is close to the color temperature of daylight, which is most acceptable and comfortable to the human eye. Such lighting used for vehicle nighttime illumination can effectively reduce driver's visual fatigue, directly and significantly improving driving safety. 4. Long service life: Xenon headlights have no tungsten filament, eliminating the problem of filament breakage, with a service life of approximately 2000-3000 hours. 5. Easy installation: Installation is convenient; simply plug the headlight power connector into the ballast input end, connect and secure the bulb (the xenon lamp base is the same as the original halogen lamp base).

What Level of Wind Can a Car Withstand?

Car can withstand depends on the vehicle's weight, shape, and wind exposure area. Here are the relevant details: 1. Precautions: Generally, winds of level 6 to 7 can affect driving. If a typhoon warning is issued, it is advisable to avoid driving. 2. Hazards: Driving in strong wind conditions reduces the car's stability due to the wind force. Additionally, dust and debris in the air can impair the driver's visibility, affecting normal observation and judgment. In such conditions, the braking distance of the car increases in case of emergencies. If the wind is excessively strong, driving in such weather can easily cause the vehicle to skid sideways, and in severe cases, may even lead to rollover.

What Causes the Malfunction Light to Illuminate After a Vehicle Inspection?

During the inspection, the vehicle undergoes tests such as exhaust emissions and braking performance, where inspectors may forcefully apply the brakes or pull the handbrake sharply. This can easily trigger the malfunction light to alert the owner. Additionally, during the exhaust emission test, the drive wheels need to operate on rollers, which can easily activate the vehicle's anti-skid system. Therefore, the lights that typically illuminate after an inspection are the ESP and ABS malfunction indicators. Here is some additional information: 1. Initial Inspection: The inspection conducted to apply for a vehicle license plate is referred to as the initial inspection. Its purpose is to verify whether the vehicle meets the conditions for obtaining a license plate. 2. Definition: National regulations stipulate that vehicles must periodically pass tests including exhaust emissions, exterior appearance, lights, brakes, and chassis, and must have no traffic violation records to receive an inspection compliance sticker. All inspection dates are based on the registration date listed on the vehicle's license, and safety technical inspections must be conducted within the specified periods from the date of registration, commonly referred to as "annual inspection" or "annual review."
