9. Handling Precaution and Guideline for Li-Polymer Rechargeable Batteries
This document of ‘handling precautions and guideline for rechargeable batteries’ shall be applied to the battery cells manufactured by VTCBATT. It is advisable to contact VTCBATT in advance if and when the customer needs other applications of operating conditions than those described in this document. Additional experimentation may be required to verify performance and safety under such condition. VTCBATT will take no responsibility for any accident when the cell is used under other condition. VTCBATT will inform, in a written form, the customers of improvement(s) regarding proper use and handling of the cell, if it is deemed necessary.
1. Charging
1.1 Charging Current: Charging current should be less than maximum charge current specified in the Specification Approval Sheet.
1.2 Charging Voltage: Charging voltage should be less than the maximum nominal voltage 4.2V, and the charging voltage upper limit is 4.30V (single pack).
1.3 Charging Temperature: The cell should be charged within the range specified in this Specification Approval Sheet.
1.4 Notes: Since charging with constant current or constant voltage, reverse charging is prohibited. In case of the cell is connected improperly, the cell cannot be charged. Simultaneously, the reverse charging may cause damaging to the cell which may lead to degradation of cell performance and damage the cell safety, and could cause heat generation or leakage.
2. Discharging Current
The cell shall be discharged at less than the maximum discharge current specified in the Specification Approval Sheet. High discharging current may reduce the discharging capacity significantly or cause over-heat.
3. Discharging Temperature
Discharging Temperature should be within the range specified in this Specification Approval Sheet.
4. Over-Discharge
Over-discharging will cause cell low-performance and function loss. The cell would be in an over-discharged state by its self-discharge characteristic. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.75V and 3.95V.
5. Protective Circuit Module (PCM)
5.1 The cell/battery pack shall be with a PCM that can protect cell/battery pack properly. PCM shall have functions of:
- Overcharge prevention
- Over-discharge prevention
- Over current prevention to maintain safety and prevent significant deterioration of cell performance. The over current can occur by external short circuit.
5.2 Overcharge Protection: Overcharging prevention function shall stop charging if any cell of the battery pack reaches 4.30V.
5.3 Over-discharge Protection: Over-discharging protection function shall monitor the voltage of every cell in the pack.
6. Storage
Cells should be stored in proper temperature specified in datasheet.
10. Notice
10.1 Handling of Cells
- Avoid any short-circuit; it will cause the pole hot and lost electronic functions.
- Soft packing is very damaged by sharp edge parts such as needles and knives. Avoid cells touch with sharp edge part, when handling and storage.
- Besides the poles is the sealed edge. Don’t bend or fold dealing edge, for it is a sensitive part.
- Don’t open the folding edge on both sides of the cells.
- Don’t bend the tabs, for the tabs are not so stubborn.
- Avoid mechanical shock to the cells.
- Don’t put the cells into the heater, washing machine or high-voltage container.
- Don’t use the charger without any safety guarantee, and recommend you use specified charger.
- You should immediately stop charging, as cell is overheating, delivery any smell, changed color, distortion etc.
- Before children use batteries, adults should explain the usage first.
- Before use batteries, please read the handling guideline carefully and fully understand.
- Away from the static-electronic field, while using, charging and storing cells.
- Don’t put the cells together with metal conductors such as chains, barrette, bolt into the pocket or stored them together.
- Don’t use metal conductor to short cut the positive and negative poles.
- Don’t mis-assemble the positive pole with the negative one.
10.2 Notice for Designing Battery Pack
10.2.1 Package Design
- Battery pack should have sufficient strength and battery should be protected from mechanical shock.
- No sharp edge components should be inside the pack containing the battery.
10.2.2 PCM Design
- The overcharge threshold voltage should not exceed 4.25V (single pack)
- The over-discharge threshold voltage should not be lower than 2.40V (single pack)
- The PCM should have short protection built inside.
10.3 Notices for Assembling Battery Pack
10.3.1 Tab Connection
- Ultrasonic welding or spot welding is recommended to connect battery with PCM or other parts.
- If apply manual solder method to connect tab with PCM, below notice is very important to ensure battery performance:
- The solder iron should be temperature controlled and ESD safe.
- Soldering temperature should not exceed 350℃.
- Soldering time should not be longer than 3 seconds.
- Keep battery tab cool down before next time soldering.
- Directly heat cell body is strictly prohibited. Battery should be damaged by heat above approx. 60℃.
10.3.2 Cell Fixing
- The battery should be fixed to the battery pack by its large surface area.
- No sharp edge at the assembling position.
- No cell movement in the battery pack should be allowed.
11. Others
- The disassembling may generate internal short circuit in the cell, which may cause gassing, firing, or other problem.
- Prohibition of Disposing Cells of Fire: Never incinerate or dispose the cells of fire, for these may cause burning of the cells.
- The cells should never be soaked with liquids such as water, drinks or oil.
- Prohibit using the cells mixed with different manufactories. Prohibit using new cells mixed with old ones.
