Warnings!
To prevent the possibility of the cell from leaking, heating, explosion, please observe the following precautions:
(It should be indicated especially in manual or instruction for users.)
• Do not use and leave the cell near a heat source such as re or heater.
• Do not use or leave the cell under the blazing sun (or in heated car by sunshine).
• Do not use or leave the cell at very high temperature conditions (e.g., strong direct sunlight or a vehicle in
extremely hot conditions). Otherwise, it can overheat or catch re or its performance will be degenerate and its
service life will be decreased.
• Do not short circuit, over-charge or over-discharge the cell.
• Don’t immerse the cell in water and seawater. Please put it in cool and dry environment if no using.
• Don’t reverse the positive and negative terminals
• Do not disassemble or modify the cell.
• Do not transport or store the cell together with metal objects such as necklaces, hairpins, coins, etc.
• Make sure the cell is not with conspicuous damage or deformation.
• Don’t connect the cell to an electrical outlet directly.
• If the cell leaks and the electrolyte splashes into the eyes, rinse the eyes with clean running water immediately
for at least 15 minutes, and go to hospital for treatment if necessary.
• Mixed use of cells of different types is not allowed.
• Keep the cell away from babies.
• Do not directly solder the cell and pierce the cell with a nail or other sharp object.
• Do not strike, throw or trample the cell.
• Use the cell charger specically for that purpose when charging.
• Please separate cells of different electrochemical systems from one another when disposing of secondary cells.
• Clean the terminals with a dry cloth before use if the cell terminals are dirty. Otherwise power failure or charge
failure may occur due to the poor connection with the instrument.
• Cells should be removed from the device or charger immediately and not used again if they are over heat, give
off odor, discolor or deform, or appear abnormally in any way during use, charging and storage.
• The cell replacement shall be done only by either cell supplier or device supplier instead of the user.
• Please tape the terminals to insulate cells before discarding them in case of re and explosion.
• Do not use cells in strong electrostatic and magnetic occasions, otherwise, it can cause safety problems easily.
• Use of damaged cells is not permitted.
• Make sure package designing will not cause cell damages.
• Cell packing should be conducted strictly according to level range, any misuse of different levels should not be
permitted.
• Disassembling cells from pack or module is not permitted unless under the guidance of professional technicians.
