What is the general lifespan of an automobile motor?

[StLane]

Generally around 15 years, but a high-quality, well-maintained engine can last up to 20 years. A major overhaul is typically performed at 150,000 kilometers to extend its service life. For private vehicles that have been in use for 15 years, inspections are required every 6 months (twice a year) until they fail the inspection. Charging time: Generally, the larger the battery capacity, the longer the charging time. For example: A 12V48AH battery indicates a voltage of 12V and a capacity of 48AH. Using an external charger with a 4.8A current, it takes approximately 14 hours to fully charge. Charging method: While the car is running, the alternator replenishes the battery. However, when the battery is severely depleted, immediate recharging is necessary. The car's own charging capacity is insufficient in such cases, and a portable charger must be used. It takes about 20 hours to charge a car's starting battery.
