1. The capacity is high at the same volume. Taking the common 5 battery as an example, the nominal capacity of the nickel -metalized battery can reach 2900mAh (Mianho), while the nickel -cadmium battery is only 1100mAh (Mianho).

　　2. Nickel -hydride batteries have a larger output current than carbon and zinc batteries or alkaline batteries. It is relatively suitable for high -power products. Some special models of power types even have a larger output current than ordinary nickel -cadmium batteries.

　　3. The less obvious memory effect, even many brands of nickel -hydride batteries have claimed no memory effect.

　　4. Long cyclic life, which can be used more than 500 times under correct use conditions.

　　5. The self -discharge rate of the old nickel -hydride battery is high, and the self -discharge rate is 30-35 % under full temperature.

　　6. Poor high temperature resistance, try not to make the temperature of the battery higher than 45 degrees. Otherwise, the life span will be reduced quickly, and the internal resistance of the battery will increase.
