cr2032 3v lithium battery

　　What are the symptoms before a cr2032 3v lithium battery fails?

　　Before the cr2032 3v lithium battery fails, it will have common symptoms such as difficulty in starting, battery failure light, abnormal noise when starting, and battery observation hole. In addition, when using the car, try to avoid using electrical equipment for a long time and do not overcharge. The details are introduced below. related information.

　　1. Precursors of cr2032 3v lithium battery failure

　　1. Difficulty starting the car

　　In the absence of other factors, if your car suddenly has difficulty starting, it may be a sign that the battery is about to fail. If it is winter, there is another possibility, which is the so-called cold start difficulty.

　　2. When the car is idling, the lights dim

　　For example, when waiting at a red light or temporarily parking, your headlights suddenly dim. This is because the charging power of the engine decreases when idling. If the battery is almost unusable at this time, and it also needs to supply power to other equipment in the car, the car headlights will consume a large amount of power, resulting in insufficient power supply, resulting in dimming of the lights.

　　3. The battery fault light is on

　　When the battery fault light comes on, it reminds you that you should go to a repair shop for maintenance and testing of the battery.

　　4. Abnormal noise occurs during startup

　　Due to the weakening of the battery's discharge capacity, the starter will run poorly and make a squeaking sound. This situation is especially obvious at low temperatures. Because the weather is cold, the activity of the battery will also decrease, but it will be improved or disappear after the weather warms up. , so many car owners don’t take it seriously.

　　5. Battery observation hole

　　There is an observation hole on the maintenance-free battery. The light in the observation hole shows whether the battery is working well. If it is green, it means good, and if it is black, it means the battery needs to be replaced. However, some car owners also report that this light is unreliable and they cannot start even if it is green. Car, observation hole as a simple reference.

　　6. The battery surface bulges and leaks.

　　The main thing here is to check whether the battery is bulging or leaking. If such a situation is found, please replace it in time. If not, there will be safety hazards. Remember to replace it.

　　2. Misunderstandings about using car batteries

　　1. Any operation of using electrical equipment in the car for a long time after turning off the engine will cause the battery to be over-discharged. For example, if you forget to turn off the lights after parking at night, the engine will not start the next day. A large part of the reason is due to the failure to turn off the car in time. Turning off the lights causes the battery to become depleted, at which point the battery's performance may have been significantly reduced.

　　2. After shutting down the engine, you should try to avoid using electrical equipment, such as stereos, DVDs, radios, lights, air conditioners, etc., for no longer than 30 minutes. If you must use electrical equipment, it is best to start the engine with the generator. electrical energy.

　　3. When the engine is started, the battery will discharge with high current, but long-term high current discharge will greatly damage the battery. Each start time should not exceed 5 seconds. If it is started twice in a row, there should be an interval of 10 to 15 seconds.

　　4. Since the raw materials for manufacturing batteries cannot be 100% pure, there will always be impurities mixed in the middle, so the battery will inevitably have automatic discharge. The anti-theft alarm also needs electricity after turning off the engine. Therefore, for a long time When a vehicle is parked and not in use, the battery may be over-discharged. If the vehicle is parked for more than a week, please remove the negative connector of the battery and cut off the power supply.

　　5. Try to avoid using the cr2032 3v lithium battery with external high-power electrical equipment. Such equipment consumes a lot of electricity and may cause the battery to over-discharge. If it must be used, it is best to start the engine while using it and let the generator Powered by the battery.

　　6. Do not overcharge. If the voltage regulator of the car alternator is not set correctly, the output voltage of the alternator will be high. When the charging voltage exceeds the maximum limit voltage of the battery, overcharging may occur. At this time, If the fault is not checked and eliminated in time, the battery will overheat, causing abnormal consumption of electrolyte. Overcharging will accelerate the decomposition of active materials on the battery plates, causing the battery to fail.
