- 5. 5. Do not pierce a hole in the battery with sharp things. (such as nail, knife, pencil, drill)
- 6. 6. Do not use with other batteries or cells.
- 7. 7. Do not solder on battery directly.
- 8. 8. Do not press the battery with overload in manufacturing process, especially ultrasonic welding.
- 9. 9. Do not use old and new cells together for packing.
- 10. 10. Do not expose the battery to high heat. (such as fire)
- 11. 11. Do not put the battery into a microwave or high pressure container.
- 12. 12. Do not use the battery reversed.
- 13. 13. Do not connect positive(+) and negative(-) with conductive materials (such as metal, wire)
- 14. 14. Do not allow the battery to be immerged in or wetted with water or sea-water.
- 15. 15. Do not give immoderate heat and force to battery cell during a welding process of metal plates on it.
Pack shall meet under condition to maintain battery safety and last long performance of the lithium rechargeable cells.
1) 1) Installing the battery into the pack
- 1. 1. The cell should be inspected visually before battery assembly into the pack.
- 2. 2. Damaged cell should not be used. (damaged surface, can-distortion, electrolyte-smell)
- 3. 3. Different Lot Number cells should not be packaged into the same pack.
- 4. 4. Different types of cells, or same types but different cell maker’s should not be used together.
2) 2) Design of battery pack
- 1. 1. The battery pack should not be connected easily to any charger other than the dedicated charger.
- 2. 2. The battery pack has function not to cause external short cut easily.
- 3. 3. The design of battery pack and its structure should be reviewed physically, mechanically and electrically not to cause cell imbalance.
- 4. 4. The battery pack for multiple cells should be designed to monitor the voltage of each bank.
3) 3) Charge
- 1. 1. Charging method is Constant Current-Constant Voltage (CC/CV).
- 2. 2. Charging should be operating under maximum charge voltage and current which is specified in the product specification.
