Precautions for Charging Lithium-Ion Batteries
General Safety Tips
- Use Appropriate Chargers: Always use the charger provided with the device or a reputable third-party charger specifically designed for the device. Incompatible chargers can cause overcharging or undercharging, leading to safety issues.
- Safe Charging Environment: Charge batteries on a heat-resistant, nonflammable, and nonconductive surface. Avoid direct sunlight, hot surfaces, or locations where the battery might be exposed to heat.
- Monitor Temperature: Do not charge batteries at temperatures greater than 45°C (113°F) or less than 0°C (32°F). Ensure the charging area is cool, dry, and well-ventilated.
- Avoid Flammable Materials: Keep flammable materials away from the charging area to prevent fires.
- Inspect Batteries: Before charging, inspect batteries for any signs of damage. Immediately discard puffy or damaged batteries.
Charging Practices
- Correct Charger Settings: Ensure the charger settings match the specifications of your battery pack, including voltage and current settings.
- Avoid Overcharging: Never leave a battery pack unobserved during charging. Overcharging can lead to overheating and potential thermal runaway.
- Balance Charging: For series packs (2S and above), use a charger capable of balancing individual cell charges to prevent overcharging.
- Monitor for Anomalies: Periodically check for any unusual odors, changes in shape, or excessive heat during charging. Discontinue use if any anomalies are observed.
Electrical Safety
- Proper Electrical Connections: Plug chargers directly into wall outlets. Avoid using extension cords unless necessary and safe.
- Certified Electrical Work: Ensure all electrical work is compliant with local safety standards to prevent faulty wiring.
Special Considerations
- Transportation: Protect battery terminals during transport by using original packaging or suitable containers.
- Device Safety: When using devices powered by lithium-ion batteries, especially in new products like e-micromobility devices, follow manufacturer guidelines and ensure compliance with safety standards.
Disposal
- Proper Disposal: Do not dispose of lithium-ion batteries in regular trash. Recycle them at designated facilities.
