What are the performance indicators of Ni-MH batteries?

What are the performance indicators of nickel-hydrogen batteries? Rated capacity of nickel-hydrogen batteries: refers to the amount of electricity released by the battery under certain discharge conditions to the terminal voltage; according to the IEC standard, the rated capacity of mh-ni batteries means that the battery is at 20±5℃ Charge for 16 hours and discharge 0.2~1.0v power at 0.1℃. Ni-MH battery rechargeable Ni-MH battery multiplier: refers to the battery based on the current of 1 unit of rated capacity, when a certain current is used for charging and discharging, and the corresponding current ratio, we call it current XC; for example, about AA2000mAh battery , Its unit rated capacity current is 2000mA. When charging and discharging are 400mA, 2000mA or 4000mA, the corresponding current ratio is 0.2, 1, 2. We call it current 0. 2C1C2C. Ni-MH battery internal resistance: refers to the internal impedance encountered by the battery during charging and discharging; the internal resistance of the battery includes ohmic resistance and polarization resistance. Ohmic resistance refers to the resistance, ionic resistance and contact resistance of each element, and is related to the electrode structure and assembly process. Polarization resistance is formed by electrode reaction, which is related to the nature of electrode reaction and battery material. The smaller the battery's internal resistance, the smaller the voltage drop caused by the battery's working output current, the higher the battery's output working voltage and current, and the larger the output energy and capacity. Self-discharge: After the battery is fully charged, it will not be used for a period of time. This phenomenon of capacity reduction or loss is called self-discharge. Cycle life of Ni-MH battery: Rechargeable batteries go through a process of charging and discharging, which is called cycle or cycle. Under a certain charge and discharge system, the number of cycles that the battery can withstand before the battery capacity drops to a certain value is called the cycle life of the rechargeable battery.
