CR2025 battery

　　What does a CR2016 battery do and when does it need to be replaced?

　　The CR2016 battery can provide a strong starting current for the starter and assist the generator to supply power to electrical equipment. When the car has difficulty igniting, the battery light comes on, or the battery case leaks, it indicates that the battery needs to be replaced. Here is a detailed introduction .

　　1. What is the function of CR2016 battery?

　　1. When starting the engine, provide a strong starting current to the starter.

　　2. When the generator is overloaded, it can assist the generator to supply power to electrical equipment.

　　3. When the generator does not generate electricity or the voltage is too low (lower than the battery terminal voltage), supply power to the electrical equipment.

　　4. The battery is also a large-capacity capacitor, which can protect the car's electrical appliances.

　　5. When the generator terminal voltage is higher than the voltage of the lead-acid battery, part of the electrical energy is converted into chemical energy and stored, that is, charging.

　　2. What symptoms prove that the battery should be replaced?

　　1. Difficulty in starting a fire

　　Under normal circumstances, when we start the vehicle, the engine will respond within 1 second and start within 2-3 seconds. If you suddenly find that it is very difficult to start your car, you will always feel that it is weak to start when igniting, and you need to repeat it. It takes several times to start the car, and you can still hear a "click" sound when the ignition is turned on. It must be that the battery is dead.

　　2. The battery light is on

　　Observe the car dashboard. When the battery fault light comes on, it reminds you that you should go to the repair shop to check the battery and replace it. Sometimes even if the battery fails, the battery fault light will not come on. Instead, a series of fault lights will light up, such as the air bag fault light, engine fault light, etc. These may be chain reactions caused by battery failure, because battery failure It will cause chaos in the driving computer system.

　　3. Battery case leaks

　　If you find obvious swelling, deformation or bulging on both sides of the battery, or if there are white or green powder-like objects on the battery pile head, it proves that there is something wrong with the battery, and it needs to be replaced in time, because those are all oxides of the battery. . If you don't replace it, there will be safety hazards. Remember to replace it to reduce the wear and tear of the car and avoid safety hazards.
