The battery will start charging only when the engine speed meets the power generation requirements of the generator and reaches a stable output power. Below are detailed introductions about automotive batteries: Functions: The battery is used to store electrical energy. Without it, the car cannot operate normally. Charging During Driving: Typically, household car batteries are 12V, with a no-load voltage around 13V and a load voltage not lower than 11V. If the voltage drops below this level, it may cause difficulty in starting. The battery can be charged by the generator while the car is running. If the car is parked for a long time, it can easily lead to battery power loss, making the car unable to start. Therefore, during long-term parking, it is best to start the vehicle at least once a week for more than 5 minutes to charge the battery. Charging Precautions: Generally, it takes 4-5 hours to fully charge the battery. Avoid overcharging.

What tires are most suitable for the Golf?

Golf uses tires with the model number 205/55/R16. Car tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and high and low temperatures while driving. Below is an introduction to tires: The role of tires: Tires not only bear loads and roll but also, through the friction generated between their tread blocks and the road surface, serve as the source of power for driving, braking, and steering. Tire lifespan: The general lifespan of a tire is 6 years. Moreover, when a vehicle is overloaded, the pressure on the tires increases, and if tires are overloaded for a long time, their lifespan will be shortened. According to research, tires operating under 120% load for extended periods will see their lifespan reduced by 30%.
