How to maintain nickel-cadmium batteries?

How to maintain the nickel-cadmium battery? The battery life refers to the number of charge and discharge times before the charge and discharge capacity drops to 80% of the nominal capacity after a period of use. It is not the battery life that cannot be charged or discharged or completely fails; self-discharge rate It refers to the phenomenon that the battery slowly self-discharges when it is left unused for a long time after fully charged. The low self-discharge rate indicates that the capacity drops less after long-term storage. For shooting programs or news interviews, portable video recording equipment is generally used. The batteries used in conjunction with portable video recording equipment are a vital part of ensuring the smooth progress of the filming work if they can work for a long time with high efficiency and high quality. The normal function of the battery is closely related to the correct use and careful maintenance of our TV and audio-visual workers in their daily work. Therefore, the use and maintenance issues should arouse our attention. 1. In daily work, you should be familiar with the type of battery you use, its basic characteristics and performance. This is of great significance in guiding us to use and maintain it correctly, and it is also extremely important in extending the service life of the battery. 2. When charging, the room temperature should be controlled between 10°C and 30°C, and cooling measures should be taken when the temperature is higher than 30°C to prevent the battery from deforming due to overheating; when the room temperature is lower than 5°C, insufficient charging will occur. Affect the service life of the battery. 3. After the battery has been used for a period of time, due to the different degree of discharge and aging, there are more or less insufficient charging and performance degradation. Generally, the nickel-cadmium battery can be charged and discharged after about 10 cycles of charging and discharging. Recharge. The method is to extend the charging time about twice as long as the normal charging time. The specific example is as follows: Use SONY's BC-1WA(B) charger to charge the Np-1 battery. When the green light flashes, it is fast charging. When the green light stops flashing and keeps on, the fast charging ends. The drip charging starts. When the drip charging time is extended, The drip charging time is the overcharge time, and the overcharge time is preferably 3-4 hours. 4. The battery charging and discharging should be operated in strict accordance with the requirements and specifications, and avoid long-term overcharging, overdischarging or frequent undercharging. Incomplete discharge, long-term low-current deep discharge or short-circuit when the battery is in use are all important factors that cause the battery to decrease in capacity and shorten its life. In the long run, illegal use and operation will not only affect the use, but also inevitably affect the capacity and life of the battery. 5. In the commonly used BC-1WA(B) chargers, the battery charging process should be completed at one time. Do not cut off the power halfway or after the fast charging is over, the battery is in a high temperature state, and the power supply is reconnected so that the charger can quickly charge the battery again. Charging will result in overcharging. When the battery warning indicator flashes during use, the battery should be replaced in time to prevent excessive discharge of the battery.
