Charter for the Proper Use of Lithium Batteries 1. Handling and Storage • Avoid Shock : Do not drop or impact the battery. Shock can damage the battery and compromise its safety. • Storage in a Dry Place : Store batteries in a cool, dry place away from moisture and extreme temperatures. • Avoid Extreme Temperatures : Do not leave batteries exposed to very high (above 60°C) or very low (below -20°C) temperatures. 2. Loading • Use the Proper Charger : Always use a charger that is compatible with your lithium battery. An improper charger can damage the battery. • Do Not Overcharge : Avoid charging the battery beyond its maximum capacity. This can shorten its lifespan and increase the risk of overheating. • Monitor the Charge : Do not leave the battery charging unattended for long periods. 3. Discharge • Do Not Completely Discharge : Avoid letting the battery completely discharge. This can damage the cells and reduce the battery capacity. • Regular Charging : Recharge the battery when the charge level is low (around 20%). 4. Security • Temperature Monitoring : While charging, monitor the battery temperature. If it becomes abnormally hot, disconnect it immediately. • Avoid Short Circuits : Do not allow the battery terminals to come into contact with metal objects, which could cause a short circuit. 5. Elimination • Recycling : Do not throw lithium batteries in the trash. Take them to an appropriate recycling center for safe disposal. Lithium Battery Charging Principles 1. Initial Charge Phase : During the first charge, it is recommended to fully charge the battery to calibrate the battery management system. 2. Constant Current Charging : During the charging phase, the battery is usually charged at a constant current until it reaches approximately 70-80% of its capacity. 3. Constant Voltage Charging Phase : After reaching 70-80%, the charge switches to a constant voltage. The voltage is maintained until the battery reaches its maximum capacity (100%). 4. Charge Termination : Once the battery is fully charged, the charger should automatically stop charging to prevent overcharging. 5. Cell Balancing : For batteries with multiple cells, balancing may be necessary to ensure that all cells are charged evenly. By following this charter and these principles, you will help extend the life of your lithium batteries and ensure their safe use.
