Are all car batteries 12 volts?

Car batteries are basically 12V. Car batteries use lead-acid batteries, which are composed of 6 cells connected in series, with each cell having a voltage between 1.7 and 2.1 volts. Car batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. The batteries commonly referred to as car batteries are lead-acid batteries, which are mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. The normal service life of a car battery ranges from 1 to 8 years, depending largely on the condition of the vehicle. If the vehicle's alternator is charging normally and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years.

How to Turn on the Air Conditioning for Cooling in a Car?

Method to turn on the car air conditioning for cooling: Turn on the car's air blower, then press the AC switch, and rotate the temperature control knob to the blue position. For automatic air conditioning, press the auto button to light it up, and press the AC button to activate the cooling mode. Generally, the blue button on the left side of the car represents cold air, the red one represents warm air, and the middle one represents a moderate temperature. The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state. It provides a comfortable environment for passengers, reduces travel fatigue, creates good working conditions for the driver, and plays an important role in ensuring safe driving as a ventilation device.

How Many Years After the Vehicle's Initial Exemption from Inspection Does It Need to Be Inspected?

After the initial six-year exemption from inspection, vehicles need to undergo on-site inspections. For non-commercial private vehicles with fewer than nine seats, from six to ten years of use, they must be inspected every two years. From ten to fifteen years of use, they must be inspected annually. Vehicle annual inspection (or motor vehicle annual inspection) refers to the annual examination of vehicles that have already obtained official license plates and registration certificates, conducted according to the technical conditions for safe operation of motor vehicles. The purpose of the vehicle annual inspection is to check the main technical conditions of the vehicle, encourage enhanced maintenance and upkeep, ensure the vehicle is always in good condition, and guarantee driving safety. The annual inspection of motor vehicles is divided into the initial annual inspection and regular annual inspection.

What does Nm mean in cars?

Nm in cars is the unit of torque, which is an important performance parameter of an engine. Torque refers to the maximum moment that the crankshaft can output. The unit of torque is the product of the unit of force and the unit of distance, namely Newton-meter, abbreviated as Nm. Torque is a form of force acting on an object, causing it to rotate, with the magnitude equal to the product of the force and the lever arm (the distance from the force to the center of rotation). Under the condition of fixed power, the torque of a car is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa. This reflects the car's load capacity within a certain range.

Does a new car need underbody armor?

Whether a new car needs underbody armor depends on the owner's needs. Installation is recommended if frequently driving on special road conditions. Underbody armor is a high-tech adhesive rubber asphalt coating that can be sprayed on areas such as the car's chassis, fuel tank, and lower guard plates. These exposed areas are prone to damage from the elements, and underbody armor quickly forms an elastic protective layer to provide excellent protection for the vehicle's chassis. Underbody armor is non-toxic, offers high coverage and adhesion, and can be applied to exposed parts like the vehicle's chassis, wheel hubs, fuel tank, lower panels, and trunk. Once dried, it forms a durable elastic protective layer that prevents impacts from flying stones and gravel, as well as protects against moisture, acid rain, and salt corrosion on the metal chassis, preventing rust and ensuring driving safety.
