　　Misconceptions and Suggestions on the Use of Lithium Batteries

　　Misconception 1: The first three charges of a new battery should take more than 12 hours

　　The lithium battery is already activated before leaving the factory, and there is no problem of charging for 12 hours. It can be used normally and charged and discharged.

　　Misconception 2: Lithium batteries should be discharged before charging, and should not be charged frequently. Charging once will reduce the lifespan by one time

　　Lithium batteries should avoid deep charging and deep discharging, as this can have an impact on their lifespan. It is advisable to avoid using automatic shutdown for mobile phones or systems, and to replenish the battery's power appropriately to improve its lifespan. The cycle life of a lithium battery refers to one cycle of deep charging and deep discharging, and the impact of shallow charging and shallow discharging on the battery's lifespan is not significant.

　　Misconception 3: After lithium batteries are fully charged and stored, using them as little as possible can help improve their lifespan

　　Lithium batteries should not be stored at 100% capacity for a long time, as the capacity will decay quickly. In addition, it is recommended not to store the battery for a long time, and to replenish some power after a period of time to prevent overdischarging and seriously affect the life of the lithium battery.

　　Misconception 4: The larger the charging circuit, the faster the charging

　　The charging of lithium batteries is a constant current and constant voltage charging method. Increasing the constant current charging current may not necessarily improve the charging speed. Many times, mobile phones or other systems will implement current limiting protection, and it is useless to exceed its charging limit current.

　　Misconception 5: After a lithium battery is fully charged, it is necessary to unplug the charger, which poses a danger of overcharging

　　Lithium batteries nowadays have multiple protections, including charger protection, cell protection, overcharge protection on the protection board, and first level protection on the motherboard. Don't worry about the danger of overcharging after being fully charged. Once fully charged, the protection board will cut off the circuit and charging will automatically stop. Of course, unplugging the charger in a timely manner can also help save electricity as there may be current when the charger is in standby mode.
