What should be paid attention to during the use and maintenance of Panasonic battery?
Everyone is familiar with Panasonic battery, so do you know what should be paid attention to during the use and maintenance of Panasonic battery? Here is a detailed introduction:
1. Deep discharge is strictly prohibited. The use of Panasonic battery is closely related to the discharge depth of battery. Deep discharge will lead to sulfation of the internal plate surface of the battery, increase the internal resistance of the battery, and even cause the expansion and deformation of the battery plate, which will make the active material of the plate fall off, and cause the "reverse pole" phenomenon and permanent damage of individual batteries. The discharge depth of the battery seriously affects the service life of the battery. It is necessary not to let the battery in the deep discharge state.
2. Try to avoid over-current and over-voltage charging. Over current charging is easy to cause the positive and negative plates inside the battery to bend, make the active substances on the surface of the plates fall off, cause the usable capacity of the battery to decline, and seriously cause the internal plates of the battery to be short circuited, so as to damage the battery. Over voltage charging often causes the water contained in the battery electrolyte to be separated into hydrogen and oxygen by electrolysis, which shortens the service life of the battery.
3. Replace the battery with low activity and high internal resistance in time. If the internal resistance of the battery increases, the battery whose charging characteristic can not be restored by normal charging voltage should be replaced in time. The internal resistance of the battery is generally 10-30 m Ω. If the internal resistance of the battery is more than 200 m Ω, it will not be enough to maintain the normal operation of the equipment. The battery with large internal resistance must be replaced.
4. Avoid mixing old and new batteries. Because the internal resistance of the new battery is relatively small, and the internal resistance of the old battery is increased in varying degrees. When the new battery is mixed for charging, the partial voltage of the old battery will be relatively large due to the large internal resistance, which is very easy to cause over-voltage charging. For the new battery, the internal resistance is small, the charging voltage is small but the current is too large, which is easy to cause over-current phenomenon, Therefore, in the process of charging and discharging, it should be avoided to mix the old and new batteries. When Panasonic battery needs to be replaced due to insufficient capacity of a single battery, it can only be replaced all at once, and the battery with insufficient performance index cannot be replaced alone, otherwise, the performance of the whole battery will be affected and the service life of the whole battery will be shortened due to the imbalance of internal resistance of the battery. Otherwise, when charging, if the internal resistance is large, the voltage at both ends of the normal battery will be insufficient. In the long run, the normal battery will be affected.
