Vehicle battery charging method: Prepare a charger that matches the battery's voltage and capacity. The charger voltage should not exceed 15% of the battery voltage, and the current should not exceed 15% of the battery capacity. For example, a 12V 80AH battery can be charged at around 13V and 12A. To prevent overcharging, you can connect a 12V 40W bulb in series. When the bulb's light dims and stabilizes, the charging is basically complete. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. The commonly referred to battery is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte.

What is the appropriate tire pressure for the new Focus?

According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Tire pressure, strictly speaking, refers to the air pressure inside the tire. What is the normal tire pressure in winter? In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. What is the normal tire pressure in summer? Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures.

Which is the recirculation mode in Volkswagen Polo?

The air conditioning control panel of the Volkswagen Polo has a button for switching between recirculation and fresh air modes. Pressing it once activates recirculation mode, while pressing it twice switches to fresh air mode. Correct operation of air recirculation and fresh air modes: You should not keep the recirculation mode on continuously, as prolonged use can lead to excessive accumulation of harmful gases inside the vehicle, which is detrimental to health. It's recommended to alternate between recirculation and fresh air modes. Recirculation mode closes all airflow channels between the interior and exterior of the vehicle, meaning even when the fan is on, the air drawn in comes solely from inside the car, creating an internal air circulation. Recirculation mode effectively prevents external dust and harmful gases from entering the vehicle. Usage of fresh air mode: This should be used in combination with the air conditioning or heating system. The fresh air mode allows you to breathe in outside air. During long highway drives, it's advisable to activate the vehicle's fresh air mode.
