How to activate Ni-MH rechargeable batteries?

1. High voltage cannot be used to activate Ni-MH rechargeable batteries, because the protection voltage of its protection board has an upper limit and a lower limit. High pressure will burn out the mos tube on the protection board. The positive and negative poles of the charger should be directly charged to the positive and negative poles of the battery. When the voltage rises to the lower line voltage of the protection board, the protection board will work and discharge normally. 2. The activation purpose of the new and old Ni-MH batteries is different. The short circuit test should not be used to activate the new battery. After long-term use, the capacity of the old Ni-MH battery will decrease. At the same time, the effective output of the capacitor will be affected by the oxide layer present on the internal electrodes, which will increase the internal resistance of the battery. The decrease in capacitance is irreversible. Therefore, reducing the internal resistance of the battery is the key to activating the old NiH battery. Otherwise, the old NiH battery will become increasingly unable to adapt to high-current equipment. 3. The self-discharge of the nickel-hydrogen battery is relatively large, and the power will be gradually cut off during the long-term transition, which will reduce the activity of the battery and enter the dormant state. If the battery has not been charged and discharged for many times, the output capacity cannot reach the rated capacity due to the memory effect of the Ni-MH battery. In a specific charging and discharging method, three full charging and discharging are usually performed, and the charging mode is 0.1C. This is because the battery is not activated, the charging intensity is low, and high current charging will damage the electrodes.
