Information for Safety


! Notice

1. Handling of cells

— Don't charge the cells and keep them in a charged state for a long time. ( Display units 

    should dismantle the battery )

— Avoid any short-circuit. It will cause the leads to get hot and lose electronic functions.

— Soft package is easily damaged by sharp objects such as needles and knives. Avoid touching

    the cells with sharp objects when handling and storing.

— Next to the leads is the sealed edge. Don’t bend or fold the sealing edge as it is sensitive to


— Don’t open the folded edge on the sides of the cell.

— Don’t bend the tabs as the tabs are sensitive.

— Avoid mechanical shock to the cells.

— Don’t put the cells into an oven, washing machine or any high-voltage container.

— Don’t use a charger without a safety certification. Use only a recommended charger.

— You should immediately stop charging if the cell overheats, emits an odor, changes color,

    changes shape, etc.

— Battery should be storage away from children.

— Adults should supervise the use of batteries by children.

— Before using batteries, please carefully read and understand the handling guidelines.

— Avoid electro-static discharge when using, charging, and storing cells.

— Avoid putting the battery in contact with metal conductors such as neck chains, barrettes, or

    bolts, etc.

— Don’t use metal conductors to connect the positive and negative leads together.

— Avoid errors during assembly by contacting the positive lead with the negative lead.

— Avoid use cell with serious deformation.

— Do not directly solder the pack or battery and pierce the battery with a nail or other sharp 


2. Notice for Designing Battery Pack

—  Package Design

    — The battery pack should have sufficient strength and the battery should be protected

        from mechanical shock.

     No sharp objects should be inside the pack containing the battery.

— PCM Design

     — The overcharge threshold voltage should be less than 4.3V (single pack).

     — The over-discharge threshold voltage should not be lower than 2.8V (single pack).

     — The PCM should have short circuit protection.

3. Notice for Assembling Battery Pack

— Tab connection

     Ultrasonic welding or spot welding is recommended to connect the battery with the PCM

        or other parts.

     If the tab is to be soldered to the PCM, the instructions below are very important to

        ensure battery performance.


         The solder iron should be temperature controlled and ESD safe. 

        — Soldering temperature should not exceed 350±10°C.


         Soldering time should not be longer than 3 seconds.


         Soldering times should not be fewer than 5.


         Let the battery tab cool down before soldering again.


         Direct heat to the cell body is strictly prohibited. The battery will be damaged by

            heat above approx. 60°C.

— Cell fixing 

     — The cell should be fixed to the battery pack by its large surface area.

    — The should be no sharp edges at the assembly contact area.

     — Cells must be held firmly in the battery pack; movement is not allowed.


! Others 

 Disassembly may cause an internal short circuit to the cell, which may cause out-gassing,

    fire, or other problems.

— Lithium ion battery should not have liquid flowing, but in case the electrolyte come into

    contact with the skin, or eyes, physicians, we recommend as below:

    — The electrolyte touch eyes: Flush the electrolyte immediately with fresh water for 15min.

        and medical advice is to be sought.

    — The electrolyte touch skin: Flush the electrolyte immediately with a great deal of fresh


    — Breath the released gas: Go outside to breath flash air.

    — Mis-eaten: Go to take some medical advice.

— Prohibition of dumping of cells into fire.

— 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.

— Prohibit using damaged cells. 


! Recommended Notice

— Using cells on specified facilities only.

— Using cells in normal ambition temperature. Temperature: -10~35°c, Relative Humidity:


— Using the cells, away from heat source. Don't let children play with cells. Don't drop cells.

    Charge cells with specified charger.

— Avoid the positive pole short cutting with the negative one. Avoid the cells affected with


— Useless cells should be deal with in a safety way. Don't drop them into the water or fire.
