Briefly analyze the use of nickel-metal hydride batteries

Nickel metal hydride (nimh) batteries, high-energy rechargeable batteries with positive nickel and negative hydrogen. Ni-MH batteries do not have the advantage of the memory effect, and they do not pollute the environment. Environmental protection batteries. Nickel-cadmium and lithium batteries are the same size. Compared with the mild unit price, the capacity is higher than cadmium, but lower than lithium, and the weight ratio of cadmium is more The disadvantage is that the self-discharge rate is high. Take the eb-9008 battery as an example, briefly analyze the use of nickel-metal hydride batteries. 1. Battery model: eb-90082; battery specification: Ni-MH AA16003; rated voltage: 7.2v 4. rated capacity: 1600mah 5. charging current: full charge 0.1c (160mA constant current charge for 15 hours) standard charge 0.2-0.4c (320mA) Constant current charge for 7.5 hours or 640mA constant current charge for 3.5 hours) Quick charge 1.0c (1600mA constant current charge for 1.2 hours) 6. Discharge current: 0.2-1.0c (320mA discharge to termination voltage 6.0v or 1600mA current 6.0v) 7. Charging and discharging restrictions: the maximum charging control voltage is 9.6v, and the discharge termination voltage is 6.0v. 8. Ambient temperature for charging and discharging: charging can be adapted to 0-50℃, and normal charging should be carried out at an ambient temperature of 20±5℃, otherwise the rated charging may be insufficient ; The discharge temperature is between -18°C and 45°C, which is the same as the normal charging environment temperature. The normal use of the Ni-MH battery shelf and storage environment and time can only be guaranteed at 20±5°C. 1. The battery should be stored in a cool and dry environment with an ambient temperature of -20~30°C; 2. Before using the battery for the first time , A sufficient charge and discharge pre-cycle should be carried out to activate the battery; 3. Regarding the battery that has been shelved or stored for at least three months, it should be activated by a sufficient charge and discharge cycle. Due to the high self-discharge rate of the Ni-MH battery, the battery is in an over-discharged state, which shortens the battery life and reduces the battery performance; 4. The battery should be used in an on state, and the battery should be removed from the machine when not in use to prevent the battery from being prolonged Excessive release causes damage to Ni-MH battery configuration and charging instructions 2. Please use Ni-Cd or Ni-MH dedicated chargers. If the charger is not compatible with the machine, it may not be charged or undercharged, which may damage the battery. 5. If the battery is fully charged, remove it from the charger to prevent overcharging, shorten battery life, and reduce performance. 6. The best way to use Ni-MH batteries is to charge to full, discharge to the end, prevent charging, try to prevent charging when using, especially prevent overcharging, which will shorten battery life and performance degradation. Ni-MH battery safety warning: 1. Do not store the battery in a humid or high temperature place. 2. Do not put the battery in the fire to avoid explosion. 3. Do not short-circuit the battery terminals or reverse charge the battery. 4. Do not open the battery casing. 5. Do not install the battery in a hazardous environment. 6. Do not touch the battery, if the user's hands are wet. Do not use solvents such as benzene or banana water to clean the battery. 8. Please stop using the battery when there is noise, abnormal temperature or leakage. 9. Do not squeeze or hit the battery, otherwise the battery will become hot or catch fire.
