Information for Safety
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
— 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 3.65V (single pack).
— The over-discharge threshold voltage should not be lower than 2.0V (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.
— 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.
