Car oil battery maintenance common sense

Although the service life of a battery is generally only 3 years, if used properly, its service life can be extended. In the coming of autumn, maintenance of oil batteries should be paid more attention. Today, I will introduce some points that need to be paid attention to in the maintenance of car oil batteries, so that you can enjoy a more comfortable and safe driving pleasure.

According to professionals, although the service life of a battery is generally only 3 years, if used properly, its service life can be extended. First of all, each time you start the engine, do not exceed 3 seconds. If the first start fails, do not rush to start repeatedly. Because continuous starting of the motor will cause damage to the battery due to excessive discharge, the time interval between restarting the motor should be no less than 5 seconds. Secondly, do not use electrical equipment such as CDs and cigarette lighters when the vehicle is not started. After parking, pay attention to turn off the lights and other power-consuming components, and the sensitivity of the anti-theft device should not be adjusted too high. In addition, when the vehicle is not used for a long time, it should be started regularly to charge the battery, otherwise the battery life will be shortened due to self-discharge. To avoid a sudden battery strike, it is recommended to replace the battery with a new one as soon as the replacement time limit is reached. Otherwise, the consequences will be disastrous. If the battery strikes in the urban area, you can call for rescue; if you are in an area far away from the rescue, once the battery does not work, the cost of long-distance rescue is much higher than the price of one or two batteries. When starting the car, uninterrupted use of the starter will cause the battery to be damaged due to over-discharge. The correct way to use it is that the total time to start the car each time is no more than 5 seconds, and the interval between restarts is no less than 15 seconds. In the case that the car still fails to start after multiple starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit.

Battery is an indispensable part of automobiles. According to the types of existing batteries in the market, it can be roughly divided into two types: traditional lead-acid batteries and maintenance-free batteries that have just been popularized in China in recent years. The following introduces some issues that need to be paid attention to in the use and maintenance of batteries.

Lead-acid batteries are composed of positive and negative plates, separators, shells, electrolyte and terminal posts. The chemical reaction of its discharge is dependent on the active material of the positive plate and the negative plate in the electrolyte (dilute sulfuric acid solution). Next, the grid of the pole plate is made of lead-antimony alloy. The phenomenon of liquid loss occurs in traditional batteries during use. This is because the antimony on the grid will contaminate the lead on the negative plate, causing excessive decomposition of water, and a large amount of oxygen and hydrogen will escape from the positive and negative plates, causing electrolysis. The fluid is reduced. The maintenance-free battery is made of lead-calcium alloy. Because the battery uses the lead-calcium alloy as the grid, the amount of water decomposition generated during charging is low, and the amount of water evaporation is also low. In addition, the sealed structure of the shell also releases sulfuric acid gas. Very few, so compared with traditional batteries, it has the advantages of not needing to add any liquid, less corrosion on terminal posts, wires and body, strong resistance to overcharge, large starting current, long power storage time, etc. In recent years, it has It is very popular in China. No matter what kind of battery, if it is not used for a long time, it will slowly discharge by itself until it is scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another way is to unplug the two electrodes from the battery. Note that the positive and negative electrode wires must be unplugged from the electrode column. The negative wire must be unplugged first, or the connection between the negative electrode and the chassis of the car must be unplugged. Then unplug the other end with the positive sign (ten). The battery has a certain service life and must be replaced at a certain period of time. When replacing, follow the same order as above, but when connecting the electrode wires, the order is exactly the opposite. Connect the positive electrode first, then the negative electrode.

The storage capacity of the battery can be reflected on the dashboard. When the ammeter pointer shows that the battery is insufficient, charge it in time. Sometimes it is found that the battery is not enough on the road, and the engine cannot be started. As a temporary measure, you can ask other vehicles for help. Use the batteries on their vehicles to start the vehicle. Connect the negative and negative electrodes of the two batteries, and the positive and positive electrodes. .

When starting the car, uninterrupted use of the starter will cause the battery to be damaged due to over-discharge. The correct way to use it is that the total time to start the car each time is no more than 5 seconds, and the interval between restarts is no less than 15 seconds. In the case that the car still fails to start after multiple starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit.

For wet batteries (lead-acid batteries), the density of the electrolyte should be adjusted according to the standards in different regions and different seasons. When the electrolyte is deficient, distilled water or special replenishment should be added. Do not use pure drinking water instead, because the pure water contains a variety of trace elements, which will cause adverse effects on the battery. In addition, you should always check whether the small holes on the battery cover are ventilated during daily driving. If the small holes on the battery cover are blocked, the generated hydrogen and oxygen cannot be discharged. When the electrolyte expands, the battery shell will be broken and the battery life will be affected. *Afterwards, always check the positive and negative electrodes of the battery for signs of oxidation. If so, use hot water to connect the battery wires from time to time.
