Column rechargeable battery

　　What are the signs before a car Column rechargeable battery fails?

　　Before a car Column rechargeable battery fails, it may have various signs such as difficulty in starting, the Column rechargeable battery fault light will come on, abnormal noises when starting, and bulges on the surface of the Column rechargeable battery; and after the car is turned off and the engine is turned off, you should try to avoid using electrical equipment for a long time, because it will seriously Affects Column rechargeable battery life, then I will introduce the relevant content in detail.

　　1. Precursors of car Column rechargeable 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 Column rechargeable 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 Column rechargeable 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 Column rechargeable battery fault light is on

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

　　4. Abnormal noise occurs during startup

　　As the Column rechargeable battery's discharge capacity weakens, 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 Column rechargeable 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. Column rechargeable battery observation hole

　　There is an observation hole on the maintenance-free Column rechargeable battery. The light in the observation hole shows whether the Column rechargeable battery is working well. If it is green, it means good, and if it is black, it means the Column rechargeable 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 Column rechargeable battery surface bulges and leaks.

　　The main thing here is to check whether the Column rechargeable 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. Incorrect use of car batteries

　　1. Any operation of using electrical equipment in the car for a long time after turning off the engine will cause the Column rechargeable 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 Column rechargeable battery to become depleted, at which point the Column rechargeable battery's performance may have been significantly reduced.

　　2. After shutting down the engine, you should try to avoid using electrical equipment, such as audio, DVD, radio, lights, air conditioners, etc. for a long time. The time should not exceed 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 Column rechargeable battery will discharge with high current, but long-term high current discharge will greatly damage the Column rechargeable 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 Column rechargeable 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 Column rechargeable battery may be over-discharged. If the vehicle is parked for more than a week, please remove the negative connector of the Column rechargeable battery and cut off the power supply.

　　5. Try to avoid using the car Column rechargeable battery with external high-power electrical equipment. Such equipment consumes a lot of power and may cause the Column rechargeable 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 Column rechargeable 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 Column rechargeable battery, overcharging may occur. At this time, If the fault is not checked and eliminated in time, the Column rechargeable battery will overheat, causing abnormal consumption of electrolyte. Overcharging will accelerate the decomposition of active materials on the Column rechargeable battery plates, causing the Column rechargeable battery to fail.
