Introduction
Custom lithium batteries are widely used in electronic devices, medical equipment, and industrial applications. Proper charging and discharging practices are crucial to ensure the battery’s safety, performance, and longevity. Whether you are designing a new battery system or using pre-assembled units, following these precautions can prevent accidents and maximize battery life.
Charging Precautions for Custom Lithium Batteries
- Charging Current and Voltage Limits
Exceeding the recommended charging current or voltage may damage the battery’s performance, mechanical stability, and safety. It can even lead to overheating or leakage. Always follow the manufacturer’s specifications.- The charger must support constant current and constant voltage (CCCV) charging.
- Individual cell charging current must remain below 1C.
- Temperature range for charging: 0–45°C.
- Maximum charging voltage: 4.23V.
- Safety Tips for Charging
- Avoid charging unattended or near flammable materials.
- Monitor battery temperature; discontinue charging if overheating occurs.
- Use chargers specifically designed for your custom lithium battery.
Discharging Precautions for Custom Lithium Batteries
- Discharge Current and Voltage Limits
- Individual cell discharge current must be less than 2C.
- Temperature range during discharge: -20–60°C.
- Minimum cut-off voltage: 2.75V per cell.
- Overdischarge Prevention
- Batteries can self-discharge when not in use.
- Keep cell voltage above 3.0V during storage.
- Never allow a cell to drop below 2.5V, as this may permanently reduce capacity.
Why Proper Care is Critical
Following these precautions ensures that your custom lithium battery maintains high efficiency and long cycle life. Incorrect handling may lead to:
- Reduced performance
- Shortened lifespan
- Safety hazards, including fire or leakage
