【Car owner's family car knowledge]The service life of the battery is generally only 3 years, but if used properly, its service life can be completely extended. With the advent of autumn, the oil battery should pay more attention to maintenance. Today, I will introduce some matters needing attention in the maintenance of automobile oil battery, so that you can enjoy a more comfortable and safe driving pleasure.
According to professionals, although the service life of the battery is generally only 3 years, if used properly, its service life can be completely 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 the continuous starting of the motor will cause damage to the battery due to excessive discharge, the time interval between restarting 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 turning off power-consuming components such as lights, and do not adjust the sensitivity of the anti-theft device 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. In order 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 from rescue, once the battery does not work, the cost of long-distance rescue is much higher than the price of one or two batteries. Uninterrupted use of the starter can cause the battery to be damaged by over-discharging when starting the car. The correct way to use it is that the total time to start the car each time is not more than 5 seconds, and the interval between restarting is not less than 15 seconds. In the case that the car does not start after several starts, the reason should be found from other aspects such as the circuit, the ignition coil or the oil circuit.
Batteries are an indispensable part of automobiles. According to the types of existing batteries in the market, they 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 are some issues that need to be paid attention to in the use and maintenance of batteries.
The lead-acid battery is composed of positive and negative plates, separators, shells, electrolytes and terminal heads. It is carried out below, in which the grid of the electrode plate is made of lead-antimony alloy. The liquid reduction phenomenon occurs in traditional batteries during use. This is because the antimony on the grid will contaminate the lead on the negative plate, resulting in excessive decomposition of water, and a large amount of oxygen and hydrogen will escape from the positive and negative plates respectively, causing electrolysis. fluid reduction. The maintenance-free battery is made of lead-calcium alloy. Since the battery uses 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. Therefore, compared with the traditional battery, it has the advantages of no need to add any liquid, less corrosion to the terminal head, wire and body, strong resistance to overcharging, large starting current, and long power storage time. It is very popular in the country. No matter what kind of battery, if it is not used for a long time, it will slowly discharge itself until it is scrapped. Therefore, the car should be started at regular intervals to charge the battery. Another method is to unplug the two electrodes on the battery. It should be noted that unplug the positive and negative electrode wires from the electrode column. First, unplug the negative wire, or remove the connection between the negative electrode and the chassis of the car. Then unplug the other end with the positive sign (ten), the battery has a certain service life and will be replaced after a certain period of time. The above sequence should also be followed when replacing, but when connecting the electrode wires, the sequence is just the opposite, first connect the positive electrode, and then connect the negative electrode.
The power of the battery can be reflected on the dashboard. When the pointer of the ammeter shows that the storage capacity is insufficient, it should be charged in time. Sometimes it is found on the road that the power is not enough, and the engine cannot be turned off. 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 connect the positive and positive electrodes. .
Uninterrupted use of the starter can cause the battery to be damaged by over-discharging when starting the car. The correct way to use it is that the total time to start the car each time is not more than 5 seconds, and the interval between restarting is not less than 15 seconds. In the case that the car does not start after several 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 standards in different regions and seasons. When there is a shortage of electrolyte, distilled water or special rehydration should be added, and drinking pure water should not be used instead, because pure water contains a variety of trace elements, which will cause adverse effects on the battery. In addition, you should always check whether the holes on the battery cover are ventilated during daily driving. If the holes in the battery cover are blocked, the hydrogen and oxygen produced cannot be discharged. When the electrolyte expands, the battery shell will be broken and the battery life will be affected. Finally, you should always check the positive and negative electrodes of the battery for signs of oxidation, and if so, you can often use hot water to pour hot water on the battery's wire connection.
