How long can car batteries last?

Since all cars now use fully enclosed maintenance-free batteries, it is generally impossible to replenish and inspect the electrolyte, plates, etc. You can check the color of the observation hole on the battery, which is green under normal conditions. At present, car batteries are mainly divided into water-added batteries and maintenance-free batteries. The important thing is that the battery solutions used are different. Due to the high nature of the water-filled battery, car owners should always pay attention to the consumption of battery fluid and replenish the battery with special battery fluid in time. Once the refill is forgotten and the photocell fluid is consumed, the battery will be scrapped. The maintenance-free battery is to make the battery liquid brand sealed, and the battery liquid is rarely volatilized during operation, and basically does not need to refill, so it is called a maintenance-free battery. As for the service life of the battery, it is related to the configuration of the vehicle and electrical equipment, such as navigation, multi-screen information display, remote control anti-theft, etc., because the battery continues to consume power when the vehicle is turned off, causing the battery to discharge for a long time, which intensifies Due to the consumption of plates and electrolyte, the battery of this type of vehicle will be less durable than ordinary manual transmission models, usually only for 2 or 3 years, and some cars’ battery will last for 4 or 5 years. 1. Check the height of the battery liquid level. 2. Check the specific gravity of the electrolyte. 3. Clean the outside of the battery. 4. Replenish the electrolyte. The battery is charged and discharged repeatedly. During the start-up time, the capacity seems to increase and remains stable for a period of time. After that, the capacity decreases. Unless the battery is recharged, the battery will fail. Use, this is the characteristics of positive and negative batteries. Standard methods must be used to measure battery life and determine how many times the battery can be charged and discharged under specific conditions. Determining the more important factor of the battery depends on the operating conditions of the battery.
