How do lead-acid batteries replace the electrolyte?

For cadmium-nickel powered lithium-ion battery equipment, the electrolyte should be replaced after 100 charge-discharge cycles. Infrequently used power lithium-ion battery equipment also needs to replace the electrolyte once a year. If the capacity of the power lithium-ion battery equipment is significantly reduced, the replacement period of the electrolyte should be shortened. The electrolyte is replaced once every 50 cycles of charging and discharging of iron-nickel storage batteries. According to climate change, generally no less than twice a year. The electrolyte of cadmium-nickel power lithium-ion battery equipment should be replaced by the following method. First discharge with a current rate of 8 hours to reduce the voltage of each power lithium-ion battery equipment to 1.0 volts, pour out the electrolyte, and then wash the power lithium-ion battery equipment with pure water, until it is washed from the power lithium-ion battery equipment There is no residue or sediment in the poured water. Then inject the newly prepared or regenerated electrolyte into the power lithium-ion battery equipment. Note that in any case, power lithium-ion battery equipment that has been washed with pure water must be injected with electrolyte immediately, even if it is left for a short period of time, it is not allowed. After injecting new electrolyte, tighten the stopper and let it stand for 2 hours; check whether the specific gravity and liquid level of the electrolyte meet the regulations, and adjust it if necessary. Then add an appropriate amount of liquid paraffin and tighten the stopper. Before replacing the electrolyte, the iron-nickel power lithium-ion battery equipment should be discharged with a current rate of 8 hours to reduce the voltage of each power lithium-ion battery equipment to 1.0 volts, take out the old electrolyte, and shake the power lithium-ion battery equipment vigorously. Let the residue in the container fall off. After the old electrolyte is taken out, it is cleaned 3-4 times with the old electrolyte to remove the residue. Inject the newly prepared or regenerated electrolyte into the power lithium-ion battery equipment, stand still for 2 hours, check the specific gravity and liquid level of the electrolyte and adjust it to reach the specified value. Then, add an appropriate amount of liquid paraffin and tighten the stopper. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
