一. Charging method
1. Choose the right charger
The polymer lithium battery needs to be charged with a special lithium battery charger, and the output voltage and current of the charger must match the rated voltage and current of the battery. Using an unsuitable charger will lead to battery overcharge, overdischarge, overheating and other problems, and may damage the battery in severe cases.
2. Control charging current and voltage
The charging current and voltage of the lithium polymer battery must be controlled within an appropriate range to avoid overcharging or overdischarging the battery. Generally speaking, the charging current of a polymer lithium battery should be controlled below 1C of the battery's rated current, and the charging voltage should be controlled below 4.2V of the battery's rated voltage.
3. Avoid overcharging and overdischarging
Both overcharging and overdischarging of polymer lithium batteries will have an impact on battery life and safety. Therefore, it is necessary to pay attention to controlling the charging voltage and current during the charging process to avoid battery overcharging. At the same time, it is also necessary to avoid over-discharging the battery during use. Generally speaking, when the battery power is lower than 20%, it should be charged in time.
二. Maintenance method
1. Avoid high temperature environment
Polymer lithium batteries are very sensitive to high temperature environments, and prolonged exposure to high temperature environments will shorten battery life and even damage batteries. Therefore, you should avoid exposing the battery to a high temperature environment during use, and try to keep it in an environment below 20°C.
2. Avoid excessive discharge
Excessive discharge of polymer lithium batteries will lead to reduced battery capacity and shortened life. Therefore, you should avoid discharging the battery to a low level during use. Generally speaking, when the battery level is lower than 20%, you should charge it in time.
3. Regular charging
Even if the lithium polymer battery is not used, it should be charged regularly to maintain the activity of the battery and prolong the battery life. Generally speaking, if the battery has not been used for a long time, it should be charged once a month to maintain the power and activity of the battery.
4. Avoid short circuit and impact
The short circuit and impact of polymer lithium battery will have a serious impact on the battery, and may even cause the battery to explode. Therefore, you should avoid short-circuiting or impacting the battery during use, and try to avoid contacting the battery with metal objects.
In short, correct charging and maintenance methods are very important for the performance and life of polymer lithium batteries. During use, you should choose a suitable charger, control the charging current and voltage, avoid overcharging and overdischarging, and also pay attention to maintaining the battery to avoid problems such as high temperature environment, overdischarging, short circuit and impact.
