Two common misunderstandings of lithium battery charging methods

　　1. For the charging method of the new battery, it is popular with people that the battery can be activated for more than 12 hours in the first three batteries. In fact, this statement is wrong

　　Reason 1: This sentence continues from the nickel battery, but the charging and discharge characteristics of lithium batteries and nickel batteries are very different. For lithium batteries, over -charging and overcharge will cause serious damage to the battery. Therefore, charge according to the standard time and method, and remember that the charging time should not exceed 12 hours.

　　Reason 2: After the lithium battery is fully charged, the charging will be automatically stopped, but if it is kept on the charger, there may be a charging cycle. The characteristics of the battery charging and discharge protection circuit may change, and the battery is on the edge of danger.

　　2. "Charging on demand" or "automatic shutdown, no power to charge"? Many people choose the latter when buying a new machine, but in fact this is unnecessary.

　　Reason 1: The life of lithium batteries is generally 300-500 charging cycles. Assuming that the power provided by a complete discharge at a time is 1Q, regardless of the amount of electricity decreased after each charging cycle, lithium batteries can always provide 300Q to 500Q power. 1/2 charging at a time can be charged 600-1000 times; 1/3 charging at a time can be charged 900-1500 times; if random charging, the number of charging is uncertain. In short, the total power of 300Q-500Q can be added. Therefore, the life of lithium batteries is related to the total charging capacity of the battery, but it has nothing to do with the number of charging times. Deep charging and shallow charging have little effect on the life of lithium batteries.

　　Reason 2: In fact, shallow charge is more conducive to lithium battery. Only when the power module of the product is the lithium power supply, deep charging is needed. Therefore, in the process of daily use, you cannot be restricted to charging with photovoltaic, and you can charge it in a convenient way.
