Analysis on the matters needing attention in the discharge of Ni-MH battery

Precautions for Ni-MH battery discharge 1. The unsustainable voltage of Ni-MH battery discharge is very critical and must be between 1.0 and 1.1v. Exceeding this intermittent voltage may cause the danger of over-discharge, which may cause exhaust and cause great damage to the battery. 2. The ambient temperature during discharge should be between -10°C and 45°C. Beyond this scale, the emission capacity will be severely reduced. 3. The discharge current affects the discharge power. The discharge power is preferably between 0.1c~2c. 4. Over-discharge will damage the characteristics of the battery, and over-discharge protection should be provided for discharge. Storage 1. Store the battery in a dry, non-corrosive, -20~35℃ environment. 2. Long-term storage will accelerate the self-discharge of the battery and the passivation of active materials. The voltage and capacity of the battery will drop and repeat the charge and discharge cycle several times. The battery can restore its original function, so we need to charge it regularly. Battery life After the battery is used, the internal resistance of the battery is increased, and there may be an internal short circuit. The charger and charging circuit should consider the safety issues of battery failure and heat generation in the future. Do not solder anything directly to the battery. This may damage the safety valve inside the battery and impair the safety of the battery. The equipment on the equipment (closed battery box) should prevent the use of closed battery box. In some cases, the battery has gas release. If there is a fire source, there may be a risk of battery rupture. 1. The number of combinations cannot exceed 6, and can only be used in series. 2. The discharge voltage should be strictly controlled. The general intermittent voltage is 1.1v (refers to the voltage of a single battery). 3. To strictly control charging, not overcharge, use -△V control. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
