Polymer batteries and cylindrical lithium-ion batteries and combination products are widely used in wearable devices, Bluetooth, GPS systems, electronic communication products, video and audio products, flashlights, miner's lamps, remote control toys, aircraft models, car models, electric toothbrushes, audio, digital electronic products. , emergency power, power tools, medical equipment fields and other fields.
Precautions:
First, charging
The charging current and charging voltage shall not exceed the following standards. If the specified value is exceeded, the charging and discharging performance, mechanical performance and safety of the battery may be damaged, which may cause heat and leakage. The battery charger must be able to charge at constant current and constant voltage; the charging current of the single battery during charging must be below 1C; the temperature range during charging is 0 to +45 °C; the voltage during charging cannot exceed 4.23V.
Second, discharge
The discharge current shall not exceed the following standards, and the discharge must be carried out within the scope of this standard. The discharge current of the single cell must be less than 2C; the temperature range during discharge is -20 ~ +60 ° C; the discharge termination voltage of the single cell is not less than 2.75V. It should be noted that while the cell is not in use for a long period of time, it may be in some over-discharge state with its self-discharging characteristics. To prevent overdischarge, the cell should be charged periodically to maintain its voltage above 3.0V. Overdischarge can result in loss of cell performance and battery function. Do not over discharge to make the cell less than 2.5V. If you do not use the battery for a long time, remove the battery from the battery appliance.
Third, polymer lithium ion battery storage
The long-term storage environment of the battery is: temperature -20 ~ +35 ° C relative humidity 45 ~ 75% When the battery storage period is nearly one year, the battery should be charged 10% ~ 5
