Avoid breaking down and strengthen the care of the battery
Is there a situation where a vehicle that is currently running suddenly runs out of battery and fails to get on the road and breaks down halfway? Makes people feel bad instantly! The vehicle cannot be started, and there are deserted, we can only pray for God’s blessing. The car battery supplies power to all electrical equipment on the vehicle. As small as a light bulb, as large as the ignition coil, solenoid valve, various sensors and control computer on the engine, all are under the control of the battery. The battery 'strike' means that you have to 'came on' the role of the engine, you have to push the car; if you are alone and the battery is short of electricity, you have to worry about finding someone to give you directions. This shows that the consequences of battery problems may be troublesome. In order for our vehicles to travel safely and return smoothly, we must always pay attention to the condition of the battery and take precautions. Don't let it get stuck in the middle of driving! 一. The difference between maintenance-free batteries and water-added batteries At present, our commonly used batteries are mainly divided into two types, namely ordinary batteries and maintenance-free batteries. 1. Maintenance-free battery Maintenance-free battery due to its own structural advantages, the consumption of electrolyte is very small, and there is basically no need to supplement distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of ordinary batteries. 2. Water-refillable battery The electrode plate of the water-refillable battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; its disadvantages are low specific energy (that is, electric energy stored per kilogram of battery), short service life and frequent routine maintenance. 二. Instructions for use of car battery 1. When starting the car, uninterrupted use of the starter will cause the battery to be damaged due to excessive 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. 2. When the ammeter pointer shows that the battery is insufficient, charge it in time. The storage capacity of the battery can be reflected on the dashboard. 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 poles of the two batteries, and the positive and positive poles. . 3. The density of the electrolyte should be adjusted according to the standards in different regions and different seasons. 4. Distilled water or special rehydration should be added when the electrolyte is deficient. Never use pure drinking water instead. Because the purified water contains a variety of trace elements, it will cause adverse effects on the battery. 5. If the battery 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 on the battery. It should be noted that the positive and negative electrode wires should 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 (+). The battery has a certain service life and must be replaced after a certain period of time (this period is generally 2 years). The above sequence should also be followed when replacing, but when connecting the electrode wires, the sequence is exactly the opposite, first connect the positive electrode, then the negative electrode. 6. u200bu200bAlways check whether the small holes on the battery cover are ventilated during daily driving. If the small holes in 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.
