How long is the battery life in a car?

Since the cars are now fully enclosed and maintenance-free batteries, it is generally impossible to replenish and check the electrolyte, plates, etc., and you can check the color of the observation holes on the battery, which is green in normal conditions; The service life of the battery is related to the configuration of the vehicle, electrical equipment, etc., such as navigation, multi-screen information display, remote control, etc., because the vehicle continues to consume power when the vehicle is turned off, causing the battery to discharge for a long time, which intensifies the pole. The consumption of plates and electrolytes, so the battery of this type of vehicle will be less durable than the ordinary manual transmission models, usually only used for 2 or 3 years, and some cars will be used for 4 or 5 years.

The battery should be regularly checked for the height of the electrolyte during use, and the battery storage condition should be checked and supplemented in time. Battery maintenance work is relatively simple, do a good job of electrolyte supplement, battery and pole cleaning and battery specific gravity control, can effectively extend the battery life. Due to the widespread use of maintenance-free batteries, batteries generally do not require maintenance under normal operating conditions.

1. Clean the battery outside

2. Check the battery level

3. Replenish electrolyte

4. Check the specific gravity of the electrolyte. The battery is recharged repeatedly. During the start-up time, the capacitance seems to increase and remain stable for a period of time. After that, the capacity drops until the last time. Unless the battery is recharged, the battery cannot be used. This is the positive and negative poles characteristics of the battery. Measuring battery life must be done using standard methods and determining how many times the battery can be charged and discharged under specific conditions. Determining the most important number of batteries in a battery depends on the operating conditions of the battery.

Some car owners often complain that the battery of the car is easy to run out of electricity. What are the precautions? Here we talk about the maintenance of the battery and the problem of extending its service life.

At present, automotive batteries mainly include water-added batteries and maintenance-free batteries, mainly because the battery solutions used are different. Because of the largeness of the water-added battery, the owner of the vehicle often needs to pay attention to the consumption of the battery liquid, and supplement the battery liquid for the battery in time. Once the liquid is forgotten and the dry battery is consumed, the battery will be scrapped. The maintenance-free battery is to make the battery liquid plate sealed. During operation, the battery liquid is rarely volatilized, and basically no rehydration is required, so it is called maintenance-free battery.

Therefore, in order to make the car battery regularly run well and extend the service life of the battery, we must pay attention to the following aspects:

1. The battery should be installed securely. Always check that the battery is secure, including checking the battery cable, whether the union is secure, and whether the cable is in good contact with the connector. Otherwise, when the car is driving on bumpy road conditions, the battery may be shaken or even detached and damaged, and the loosening of the connecting wire may cause an electric spark.

2. The ignition time is controlled within 385 seconds each time if you can't catch a fire at a time do not start the interval no less than 15 seconds. If you can't get the car after multiple starts, avoid frequent fires for a long time. You should find the reason from other aspects. Long-term high-current discharge of the battery will greatly damage the internal structure of the battery.

3. Do not turn on the air conditioner when the car is idling. Because the speed of the engine is slow when the car is idling, at this time, the generator is not enough to charge the electric energy required for the operation of the car air conditioner, and only the electric energy of the battery itself can be consumed. For a long time, the battery will accelerate the loss.

4. Pay attention to cleaning and rust prevention. Pay attention to timely cleaning the oxides, sulfates, etc. generated by the battery clips. Vaseline can be applied after cleaning and scraping rust to prevent further rust. At the same time, it is necessary to remove dust and dirt from the battery cover and spilled electrolyte to help prevent self-discharge.

5. Do not replace the battery with a larger capacity than the original battery. Because the generator power generation on the car is fixed, such as changing the battery with large capacity, the new battery will be charged insufficiently, the car will not start smoothly, and the battery will lose power for a long time.

6. For water-filled batteries, the liquid level should be checked every 10 days in summer and every 15 days in winter. And add special battery liquid as needed, can not add other liquids. Otherwise it will shorten the battery life. Do not let other substances fall into the battery when adding liquid. If there is any substance falling in, do not use metal materials to fish, use dry wood rods to pinch out impurities, such as wire or copper wire to hook, metal molecules will be in hydrochloric acid. Corrosion enters the battery to form self-discharge and damage the battery.

The service life of the battery of the car is related to the characteristics of various batteries. The service life of the lead-acid battery on the market is generally 2-3 years. Now there is a lithium iron phosphate starter battery on the market, and its service life is 8-10. Years, BYD new energy vehicles are used lithium iron phosphate power batteries; like lithium tiger; 12V they are doing lithium iron phosphate battery

Today, automotive batteries can be broadly classified into maintenance-free and general-purpose batteries (not maintenance-free). Most of the models currently on the market use maintenance-free batteries, and most Japanese cars use non-maintenance batteries, which are ordinary batteries.

A common battery is also called a lead-acid battery, and its electrode is composed of an oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is that the voltage is stable and the price is cheap; the disadvantage is frequent daily maintenance. Old-fashioned ordinary batteries generally have a life span of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water.

Maintenance-free batteries, as the name suggests, are the most maintenance-free. It is basically unnecessary to replenish distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. Of course, its price will be more expensive than ordinary batteries. As for the service life, the recommended replacement period for maintenance-free batteries under normal conditions is about 3 years.

From the point of view of use and maintenance, whether your car is equipped with a maintenance-free battery or an ordinary battery, the normal service life is about 2-3 years, if you use it, it is 3 to 4 years, and the mileage is 6 to 90,000 kilometers. If you feel that you are not getting electricity or the starter is weak, the headlights are obviously darker. You need to take the battery off and charge it with the charger for 12-24 hours. If it still doesn't work, the mileage will reach more than 50,000 kilometers, and the generator is not faulty. You need to consider changing the battery.
