18650 lithium battery 2600mah

　　How to maintain 18650 lithium battery 2600mah and what are the misunderstandings?

　　For the initial charging of a new battery, one to three charge and discharge cycles should be carried out. The starting time should not exceed 5 seconds each time. Do not use the electrical equipment in the car for a long time after turning off the engine. The following is a detailed introduction to "Misunderstandings in the Maintenance and Use of 18650 lithium battery 2600mah" .

　　1. Car battery maintenance

　　1. The first charge of a new battery or a repaired battery before use is called initial charge. Whether the initial charge is appropriate or not is extremely important for the future performance of the battery. The characteristics of initial charging are small charging current, long charging time and sufficient electrochemical reaction. The initial charging operation of a new battery should be carried out for one to three charge and discharge cycles.

　　2. Each starting time should not exceed 5 seconds, and the starting interval should be greater than 15 seconds, with a maximum of 3 consecutive starts.

　　3. If there is a traffic jam or waiting for someone, in order to save fuel, most car owners are accustomed to turning off the engine and listening to the stereo or watching DVD in the car, but this will consume a lot of battery power. It is recommended that car owners should not listen to the radio for more than 30 minutes when the engine is turned off, and it is not recommended to use high-power equipment such as DVDs and external power supplies, because this can easily use up the stored power in the battery and damage the battery itself. Not small, it will also affect the normal starting of the vehicle.

　　4. If your car will not be used for a long time, it is best to unplug the negative terminal of the battery. Because there is also a weak current consumption in the vehicle circuit system when parking, leaving the vehicle stationary for a long time will cause the battery to run out.

　　5. Use a damp cloth to scrub the outside of the battery, and wipe away dust, oil, white powder and other contaminants that may cause leakage on the panel and pile heads (i.e. the positive and negative poles). By scrubbing the battery frequently in this way, not only will the pile head of the battery not accumulate white acid-etched powder, but its service life will be longer.

　　6. Do not casually replace the car's battery with a larger capacity than the original battery. Because the power generated by the car generator is fixed. If you replace the battery with a larger capacity, the new battery will be undercharged and the car will not start smoothly. Moreover, long-term battery loss will shorten the life of the battery.

　　7. When using maintenance-free batteries, simply think that maintenance-free means that no maintenance is required. Failure to charge in time after over-discharging or recharging regularly will affect the service life of the battery.

　　8. The battery should be firmly fixed on the car and should be handled with care during installation and transportation.

　　9. When using the battery in winter, special attention should be paid to keeping it fully charged to prevent freezing. When adding distilled water in winter, it should be done while charging to prevent freezing. The battery capacity will decrease in winter, so it is best to preheat the engine before starting. In winter, due to the low temperature, it will be difficult to charge the battery. The battery storage status should be checked frequently.

　　2. Misunderstandings about using 18650 lithium battery 2600mah

　　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 car 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.
