What is the function of a 2025 button cell battery and how to maintain it?

　　The function of the 2025 button cell battery is to provide starting current to the starter, assist the generator in supplying power to electrical equipment, and protect the car's electrical appliances. In addition, the maintenance of the 2025 button cell battery is to check the battery regularly to prevent the battery from being discharged with high current for a long time. Next, I will introduce the detailed content to you.

　　1. The function of 2025 button cell battery

　　1. When starting the engine, provide a strong starting current (about 10A) to the starter.

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

　　3. When the engine is at idle speed, supply power to 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 electromotive force of the lead-acid battery, part of the electrical energy is converted into chemical energy and stored, that is, charging.

　　2. Maintenance of car batteries

　　1. The electrolyte level should always be maintained between max and min. Check it once a month. Depending on the drop in the level, add distilled water (pure water) appropriately and do not add acid.

　　2. When the voltage of the battery is insufficient, the lights are dim, and the vehicle cannot start, charging outside the vehicle should be carried out in a timely manner.

　　3. Prevent the battery from overcharging or long-term power loss. Overcharging will cause the active material to fall off, and power loss will cause the plate to be vulcanized. Make sure that the voltage of the regulator is not too high or too low.

　　4. During use, you should always check whether the exhaust hole is clear to prevent the battery from deforming or bursting.

　　5. The battery should be kept away from heat sources and open flames, and ventilation should be maintained during charging and use to prevent burning and injury.

　　6. To prevent the battery from being discharged with high current for a long time, the start-up time of each use should not be greater than 5 seconds, and the time between two consecutive starts should be 10-15 seconds.

　　7. The battery should be installed firmly on the car to reduce vibration.

　　8. Always check whether the battery connection cable is firm and all loose joints must be in good contact to prevent sparks from causing the battery to explode. The oxides and sulfates produced by the battery clip must be scraped off and coated with Vaseline to prevent further corrosion.

　　9. Always remove dust, dirt and spilled electrolyte from the battery cover to keep it clean and dry to prevent self-discharge.

　　10. Cracks in the sealing tape must be repaired in time.

　　11. When driving in cold areas, avoid completely discharging the battery to prevent the electrolyte from freezing.
