Car batteries must be filled with water.
The battery is an essential part of the car and can be divided into traditional lead-acid battery and maintenance-free battery.
Since the battery uses lead-calcium alloy as the grid, the amount of water decomposed during charging is small, and the amount of water evaporation is also small. In addition, the outer casing adopts a sealed structure. and very little sulfuric acid gas is released. Therefore, compared with traditional batteries, it has the advantages of no need to add liquid, docking terminals and long energy storage time.
Severe dehydration of car batteries will cause the battery to become severely vulcanized and no longer retain electricity if the battery is caused by severe vulcanization or water loss and its appearance is not not damaged, bulging or short circuited. OrWhen there are signs of a broken circuit, you can try adding water to the battery to repair it.
Add water to repair. When adding water, you should add deionized water or purified water. Do not add tap water, which will cause the battery to self-discharge.
Repairing a battery by adding water is a very professional matter, and requires an understanding of the internal structure of the battery and its principles. Not all batteries are worth repairing by adding water. If there is no voltage or current, there is no need to repair them.
Detailed information:
1. When starting the motor, it provides a strong currentnt start to the starter. (generally up to 200 ~ 600A).
2. When the generator is overloaded, it can help the generator to power electrical equipment.
3. When the engine is idling, power the electrical equipment.
4. The battery is also a large capacity capacitor, which can protect the car's electrical appliances.
5. When the voltage across the generator is greater than the electromotive force of the lead-acid battery, part of the electrical energy is converted into chemical energy and stored, i.e., charge.
People's Daily Online - How to recharge a car battery? These parameters must be understood!
Method:
1. Use positive and negative pulses to depolarize and charge the battery, then repeat this cycle three times. capacity is If there are signs of recovery, you can perform furtherseveral additional cycles to obtain better repair results.
2. Add water for repair. When adding water, you need to add deionized water or purified water, which will cause serious battery self-discharge problem. The specific method is as follows (offline operation):
(1) Fully discharge the battery first, because the density of the acid inside the battery after discharge is basically lower at 1.1 g/mL;
(2) Remove the cover sheet and clean it for later use;
(3) Add water, usually 1 g/Ah;
(4) Let it sit for about an hour, and then the safety valve and cover are installed;
(5) Charge, then discharge completely, repeat this cycle three times.
Detailed information:
1. The car battery is the main componentipal of the car. . The battery Once the power is cut off, the car will have difficulty starting. If you start the car boldly, it will greatly damage the battery life.
2. When the engine is stalled, avoid turning on headlights or radios and other power-consuming equipment for a long time, even if the engine is idling for a long time, do not leave other power-consuming equipment energy ; the equipment has been on for a long time. For example, when you are waiting for a long red light at night, you can adjust the headlight to the width indicator light (small light), which can save power and reduce battery drain.
3. When connecting the power supply, pay attention to the positive and negative poles of the batteries on both sides and never connect them reversely. The correct connection method is: the positive terminal of the discharged vehicle batteryshould be connected to the positive terminal of the emergency vehicle battery, and then the negative terminal of the emergency vehicle battery should be connected. to the negative terminal of the discharged vehicle battery. After ensuring that the cables are connected, start the emergency vehicle (the emergency vehicle can also be started) and let the vehicle that has lost power charge.
