Basic requirements for charging of lead-acid batteries
The charging current should be less than or equal to the charging current of the battery. Otherwise, the excess current will cause the electrolyte to consume too quickly, resulting in the following hazards: the loss rate of the battery, the increase of the maintenance workload, the early failure of the battery for maintenance of the battery, the acid fog, the pollution of the environment, the health of the workers, the reduction of the charging efficiency and the energy consumption. Serious waste.
