18650 battery 3.7v 3500mah.How to activate the battery? UPS battery maintenance solution

　　How to activate the battery? UPS battery maintenance solution. In UPS power supplies, maintenance-free sealed lead-acid batteries are widely used. Good maintenance and upkeep can not only ensure the safety of power supply, but also greatly extend the service life of UPS batteries. Perform routine maintenance on the UPS battery, so as to extend the life of the UPS battery and reduce the failure rate to the greatest extent.

　　How to activate the battery?

　　1. Unscrew the plastic cover of each compartment of the battery and check the internal liquid level. If it is not enough, fill it up to the normal level.

　　2. Use a multimeter to check the voltage of each grid to see if it is basically close and whether there is reverse polarity. Whether the total voltage is above 10.8 volts. If any individual grid is found to have low voltage or reverse polarity, it must be supplemented or the polarity corrected separately.

　　3. It is best to use a charger with adjustable voltage and current and a voltage and current display meter. Connect the connection cable, turn on the power, and observe the changes in voltage and current. If it reaches 14 volts and there is still no charging current, continue to increase the voltage to 16 volts and wait.

　　4. As long as there is current, it means activation begins. Slowly wait for the current to increase. When the current exceeds one-tenth of the capacity, for example, when the current of a 24-hour battery exceeds 2.4 amps, reduce the voltage and adjust the current to 2.4 amps. Wait until the voltage drops below 14 volts and there is still 2.4 amps of current. The activation is successful and the charging stage is entered.

　　5. This kind of long-term UPS battery generally needs to be charged for more than 14 hours, and the maximum charging voltage at the end of charging does not exceed 14.9 volts.

　　UPS battery repair method

　　Pulse repair method:

　　A better way to eliminate sulfuration in batteries is to use the pulse repair method. When repairing the battery, the instantaneous voltage of the pulse is generally between 60V and 300V according to the functional needs of the product. For example, the pulse voltage value of products used to extend the battery life is not necessarily too large. Specially for battery repair products The pulse voltage value can be too large. If the pulse voltage is high, the battery repair time will be short. If the pulse voltage is low, the battery repair time will be relatively long. Although the voltage at the pulse instant is very high, the average voltage is not high, which does no harm to the human body. It is very Safety.

　　Full charge and full discharge repair method:

　　The full charge and full discharge repair method is to fully charge the battery and then completely discharge it to repair the battery. The full charge and full discharge repair method mainly has a certain repair effect on slightly damaged batteries. At the same time, this method can also effectively activate the active substances deep in the battery and increase the battery capacity.

　　Hydration repair method:

　　The "water loss" of the battery can be repaired by replenishing water. The purpose is to dilute the sulfuric acid with increased concentration to carry out the electrolysis reaction normally. The method of replenishing water is relatively simple. Just open the battery cover and you will see six round holes. Inject a certain amount of distilled water into each hole and soak it for more than 24 hours.

　　UPS battery maintenance solution

　　The UPS battery maintenance solution consists of three parts: battery pack capacity monitoring, single UPS battery charge and discharge activation, and battery-specific intelligent protection.

　　1. Battery pack capacity monitoring

　　The float voltage, current, charge and discharge voltage, and current of the UPS battery can be monitored and recorded online. After recording the discharge data, the performance of the battery pack can be judged, lagging cells can be found, and the remaining capacity of each cell can be given.

　　2. Single battery charge and discharge activation

　　For the discovered backward single cells, charge and discharge to activate the failed active material, reduce the internal resistance, compensate for the voltage difference and supplement the remaining capacity, so as to avoid the further deterioration of the backward single cell and affect other cells, that is, perform early testing on the battery. Treatment and prevention, and timely replacement of single batteries that cannot be compensated.

　　3. Special intelligent protection for batteries

　　Special intelligent protection for lead-acid batteries is a high-tech technology that uses electronic pulse technology to perform automatic daily maintenance on lead-acid batteries in use. The protector also has the function of repairing lead-acid batteries that have failed due to shock, fatigue, or overuse due to the saltation of lead sulfate on the plates. It cleverly uses the energy of the battery itself to generate electronic pulses and feeds them back to the battery. It uses electronic methods to effectively prevent the battery from stable capacity output, improve the working efficiency of the battery, fundamentally improve the working performance of the lead-acid battery, and greatly extend the battery life. life, save money and energy, and also play a positive role in environmental protection.

　　These three processes work together to solve the problem of the current lack of necessary maintenance methods and tools for UPS batteries. They can not only test the battery performance for you and find backward cells, but also help you activate the backward batteries and provide early treatment to the batteries, which is effective Prevent failures from occurring.

　　Monitoring the UPS charging system is an important part of maintaining the UPS power system. Many users neglect the monitoring of the UPS charging system due to the lack of necessary testing methods. If the UPS charging system is broken, even if a new battery is replaced, its service life will be shortened. will become shorter. The traditional method of judging UPS battery capacity is the same as that of general batteries. The entire battery pack is separated from the communication power supply system and put on a discharge meter. It is discharged at a constant current rate of 10 hours, and then the battery pack is discharged at a constant current rate that reaches the discharge termination voltage first. The discharge time and current of the battery are used to calculate its capacity.
