Teach you the correct use and maintenance of lithium batteries

Correct use and maintenance of lithium batteries 1. When using lithium batteries, it should be noted that the batteries will enter a sleep state after being left for a period of time. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, the lithium battery is easy to be activated, as long as it can be activated after 3 to 5 normal charge and discharge cycles, and the capacity is normal. Due to the characteristics of the lithium battery, it has almost no memory effect. Overcharge and overdischarge cause great damage to lithium batteries, especially liquid lithium batteries. Therefore, it is best to charge according to the standard time and standard charging method, especially not to have an ultra-long charge of more than 12 hours. 2. The principle of recharging the battery after it is used up is the nickel coin method. This method can prevent the memory effect, but it is also used when buying mobile phones and laptops. There is such an example: due to the warning that the battery is too low, the notebook computer has not been charged until it automatically shuts down. Therefore, the laptop in this example does not respond to subsequent charging and startup, and must be sent to the customer service center for maintenance. This is actually due to the low voltage caused by the over-discharge of the battery, so there is no normal charging and starting conditions. Do not charge the lithium battery too full or use no electricity. If the battery is not fully charged, it will not cause damage to the battery. It is appropriate to charge for 2-3 hours, not necessarily full. But the lithium battery should be fully charged (normal charging time) and discharged 1-2 times every 3-4 months. Lithium batteries can be stored at 20°C for more than half a year. This is due to their low self-discharge rate and most of the capacity can be recovered. In short, the lithium battery should not be higher than the maximum charging voltage when charging, and should not be lower than the minimum operating voltage when discharging. Lithium batteries must be kept above the minimum operating voltage at any time. Low-voltage overdischarge or self-discharge reactions will cause the decomposition and destruction of lithium ion active materials, which may not necessarily be reduced. Any form of overcharging of lithium batteries will cause serious damage to battery performance and even explode. Lithium batteries must be prevented from overcharging during the charging process. Do not often deep discharge, deep charge. However, after every 30 or so charging cycles, the battery detection chip will automatically perform deep discharge and deep charge to accurately assess the state of the battery. Prevent high temperature and light from shortening the life span, which can cause explosion in severe cases. If possible, it should be stored in the refrigerator. If the notebook uses AC power, please remove the lithium battery stick to avoid affecting the computer to generate heat. Prevent icing, but the freezing point of most lithium battery electrolyte is -40℃, which is not easy to freeze. If you do not use it for a long time, please store it at 40%~60% of the charging capacity. When the power is too low, over-discharge may occur due to self-discharge. Since lithium batteries will naturally age when they are not in use, they should be purchased according to the actual number of needs when purchasing, and should not be purchased too much.
