What are the repair methods for lead-acid batteries and UPS lithium batteries?

How to repair lead-acid batteries? The general lead-acid battery is composed of positive and negative plates, separators, casing, electrolyte and terminal posts. The maintenance-free battery adopts the latest designed fully sealed structure and modern processing technology in the 1990s. Make it have high performance, long life, pollution-free, maintenance-free, safe and reliable outstanding performance. The steps are as follows: 1. Prepare a syringe, distilled water (you can use cheap barreled water) 2. Discharge the lead-acid battery to a single 10.5V3, open the battery cover and leather cap 4. Use a syringe to add water to each hole About 10ml, add 15ml5 for the battery with high voltage, cover the leather cap and upper cover 6, connect the battery line, charge with the charger and after several times of charging and discharging, the performance of the lead-acid battery can be restored a lot. 1. Lead-acid battery series repair method: This method is used when the nominal voltage of a single battery is lower than 12V. For example, rechargeable emergency lights on the market often use 6V4Ah batteries. The single output of the detector is 12V. At this time, two 6V batteries can be connected to the detector for desulfurization repair (note: the battery should be based on the nominal capacity of the battery and the appropriate charging and discharging current should be selected); 2. The batteries are shunted in parallel If the temperature of the lead-acid battery rises quickly during the repair process. The charge and discharge should be reduced. At this time, you can connect the two batteries in parallel and connect to a detector circuit, the charging and discharging current is 1/2 of the original, the effect is also very good; 3. The output combination method is about the lead-acid battery that has been left for a long time or the self-discharge is serious and For batteries with severe vulcanization, this method can be used when the effect of replenishing water and charging recovery is not clear enough. This method has a better effect on heavily vulcanized batteries, when this method is actually used. The charging current is best to choose 5A. Because of the overlap of the repair function, the repair negative pulse current is greater than the positive pulse. 5A is selected to compensate for the offset of the resulting charging current; 4. Output parallel current increase method if the repaired battery has a large capacity. If it exceeds 2OAh, sometimes it is necessary to increase the charging current. At this time, two or more output terminals of the detector can be connected in parallel to the repaired battery at the same time to enhance the charging current. In the actual experiment, it is found that depending on the battery, the current of the T1000 digital multimeter DC 20A gear side test, the side tester two channels and connected to the human battery, the current gradually rises to the sum of the two currents; 5. The output parallel desulfurization method battery is seriously vulcanized , After repeated repairs, the battery with little effect. The repair function of two detectors can be connected in parallel to the repaired battery at the same time to enhance the desulfurization effect. This method is not easy to master. It should be added in the same phase, otherwise the desulfurization current will weaken, and the judgment can be based on whether the voltage and current are newly added. How to repair UPS lithium battery? UPS lithium battery.jpg The prerequisite for lithium battery repair is that in addition to the real scrap lithium battery, or the end of life, other lithium battery failure problems can be repaired. ●Keep the proper temperature. As for the general UPS lithium battery, it should be ensured that the temperature of its environment is between 20 and 25 degrees Celsius. The increase in temperature will also lead to the reduction of battery life. In addition, if the external environment temperature is too high, the internal chemical reaction speed of the battery will be increased, which in turn will increase the speed of the environment temperature. This cyclical vicious circle will rapidly accelerate the depreciation of the battery to a large extent. Thereby affecting normal use. ●Timely replacement of used/bad lithium batteries. In the continuous operation and use of lithium battery UPS, it is inevitable that individual batteries will be damaged due to the difference in performance and quality, the performance of individual batteries declines, and the storage capacity does not meet the requirements. When one/some batteries in the battery pack are damaged, the maintenance personnel should inspect and detect each battery to eliminate the damaged battery. ●The lithium battery voltage balance repair instrument can be used to test the problems of the lithium battery. Do not disassemble the lithium battery pack to test one by one. The traditional repair is to disassemble the battery pack to test. Coupled with the self-developed lithium battery life repair core technology patent, it can effectively repair the fault problem, and the repaired lithium battery can basically restore more than 80% of the capacity. ● Let the lithium battery that is close to being scrapped completely discharge, and then recharge and activate the lithium battery.
