How to repair lead-acid batteries?

How to repair lead-acid batteries? 1. Battery series repair method: This method is used when the nominal voltage of a single battery is lower than 12V. For example, 6V4Ah batteries are often used for rechargeable emergency lights on the market. The single output of the tester is 12V. At this time, two 6V batteries can be connected to the tester for desulfurization repair (remarks: according to the nominal capacity of the battery and the appropriate charging and discharging current should be selected); 2. Batteries are shunted in parallel If the lead-acid battery's temperature rises quickly during the repair process. The charge and discharge should be reduced. At this time, you can connect two batteries in parallel and connect to a tester 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 battery that has been left for a long time or the self-discharge is serious and the vulcanization is very high. This method can be used when the battery is seriously refilled and the recovery effect of charging is not obvious. 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 superimposition of the repair function, the repair negative pulse current is greater than the positive pulse, and 5A is selected to compensate for the offset of the resulting charging current. 4. If the capacity of the repaired battery is large, the output parallel increase current method. If it exceeds 2OAh, sometimes it is necessary to increase the charging current. At this time, two or more output terminals of the tester can be connected in parallel to the repaired battery at the same time to enhance the charging current. In the actual test, it is found that according to the different batteries, 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 lead-acid battery is severely vulcanized, and the battery that has little effect after repeated repairs. The repair function of two testers 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 it can be judged by monitoring whether the voltage and current are increased.
