FAQ's

Main performance parameters of rechargeable batteries part 1?

1. Capacity of Battery: Expressed in mAh or Ah or WH, 1Ah is the continuous discharge current of the battery at 1A for 1 hour. Usually, the larger the battery volume, the higher the capacity. 2. Internal resistance of the battery: The internal resistance of the battery is determined by the resistance of the electrode plate and the impedance of the ion current. 3. Battery self-discharge rate: The self-discharge rate, also known as charge retention capacity, refers to the ability of a battery to maintain the amount of electricity stored under certain conditions in an open circuit state. It is an important parameter for measuring battery performance. The self-discharge of li-ion batteries is about 1% -2%, and that of Ni-MH batteries is less than 35%,

Main performance parameters of rechargeable batteries part 2?

4. Charge discharge rate (C-rate): C is the first letter of Capacity, used to represent the numerical value of the current during battery charging and discharging. For example, when the rated capacity of a rechargeable battery is 1100mAh, it means that the discharge time can last for 1 hour at 1100mAh (1C). If the discharge time can last for 5 hours at 200mA (0.2C), charging can also be calculated based on this comparison. 5. Energy density: The average unit volume or mass of electrical energy released by a battery. Generally, at the same volume, the energy density of lithium-ion batteries is 1.8 times that of nickel hydrogen batteries. Therefore, when the battery capacity is equal, lithium-ion batteries will have a smaller volume and lighter weight than nickel hydrogen batteries.

Main performance parameters of rechargeable batteries part 3?

6. Charging cut-off voltage: When the battery is fully charged, the active substance on the electrode plate has reached a saturation state. If charging is continued, the voltage of the battery will not rise, and this voltage is called the charging cut-off voltage. 7. Discharge cut-off voltage: The discharge cut-off voltage refers to the minimum voltage allowed during battery discharge. If the voltage is lower than the discharge cutoff voltage and the discharge continues, the products formed on the electrode plate are difficult to recover during normal charging, thereby affecting the battery life. 8. Charging cycle life: After repeated charging and discharging, the battery capacity will gradually decrease to 60% -80% of the initial capacity.

What is Ni-MH Cells？
