1. Choose the right charger
• Match the charger: Make sure the charger matches the specifications of the lithium battery. Different battery models may require different types of chargers.
• Smart chargers: Try to use smart chargers with automatic detection and protection functions to prevent overcharge, overdischarge and other abnormal conditions.
2. Follow manufacturer's guidelines
• Read the instructions: Carefully read and follow the operating guidelines and safety tips provided by the charger and battery manufacturer.
Ambient temperature: Ensure that the charging environment is at an appropriate temperature (usually between 0°C and 45°C is recommended). Avoid charging at extreme temperatures to avoid affecting battery performance and life.
3. Maintain good ventilation
• Ventilated environment: A certain amount of heat is generated during the charging process, ensuring that the charging area is adequately ventilated to dissipate heat and reduce the risk of fire.
Keep away from flammable materials: When charging, the charger and battery should be kept away from flammable materials, such as paper and cloth.

4. Check the connection
• Strong connection: Ensure that the connection between the charger and the battery is strong and not loose to prevent poor contact or short circuit.
• Clean connectors: Check and clean the charging interface regularly to ensure that there is no dust, oil or other foreign matter.
5. Monitor the charging process
• Regular inspection: During the charging process, regularly check the status of the charger and battery to observe whether there is abnormal heat, odor or smoke.
• Automatic power off: If the charger does not have an automatic power off function, the charger should be unplugged immediately after full charge to avoid long charging.
6. Prevent overcharging
• Do not overcharge: do not leave the battery in a high charge state for a long time (such as 100%), which will accelerate battery aging. It is recommended to keep the battery charge between 20% and 80%.
• Timely charging: When the battery power is less than 20%, it should be charged in time to avoid damage to the battery caused by deep discharge.

7. Keep the battery healthy
• Balanced charging: Regular balanced charging (if available) is performed to ensure that the voltage of each battery cell is consistent, thereby extending the overall life of the battery.
• Storage conditions: If the battery is not used for a long time, it should be stored in a dry, cool place, and every few months a charge and discharge cycle to keep the battery active.
8. Emergency treatment
• Abnormal conditions: If the battery or charger is found to have abnormal phenomena (such as overheating, smoke, leakage, etc.), stop charging immediately and disconnect the power supply.
• Professional maintenance: When you encounter problems that cannot be solved by yourself, contact professional technicians for inspection and maintenance.
