Introduction to Ni-MH Battery Charging

1. Memory effect of Ni-MH battery Ni-MH battery and Ni-Cd battery have the same memory effect, but it is much smaller than Ni-Cd battery. Therefore, it is not necessary to perform a discharge operation every time it is charged (because improper operation will damage the battery), it only needs to be fully charged and discharged once every three months to alleviate the memory effect. 2. The self-discharge rate of nickel-hydrogen batteries is 25-35% (months) for nickel-hydrogen batteries, 15-30% (months) for nickel-cadmium batteries, and 2-5% (months) for lithium-ion batteries. The self-discharge rate of nickel-hydrogen battery is the largest, while the discharge rate of lithium-ion battery is extremely low compared with the other two types of batteries. 3. The charging method of Ni-MH battery. Neither Ni-MH battery nor Li-ion battery can withstand overcharge. Therefore, the PICKCUT control method of constant current charging of Ni-MH batteries is the best charging method to stop charging when the charging voltage reaches the highest. For lithium-ion batteries, it is best to use constant current and constant voltage charging methods. If the nickel-cadmium battery charger-DV control method is used for charging, it will affect the service life of nickel-metal hydride batteries and lithium-ion batteries.
