! Danger
Strictly prohibit heat or throw cell into fire.
Strictly prohibit throw and wet cell in liquid such as water、gasoline or drink etc.
Strictly prohibit use leave cell close to fire or inside of a car where temperature may be above 60℃.
Also do not charge / discharge in such conditions.
Strictly prohibit put batteries in your pockets or a bag together with metal objects such as necklaces.
Hairpins, coins, or screws. Do not store or transportation batteries with such objects.
Strictly prohibit short circuit the (+) and (-) terminals with other metals.
Do not place Cell in a device with the (+) and (-) in the wrong way around.
Strictly prohibit pierce Cell with a sharp object such as a needle.
Strictly prohibit disassemble or modify the cell.
Strictly prohibit welding a cell directly.
Do not use a Cell with serious scar or deformation.
Thoroughly read the user’s manual before use, inaccurate handling of lithium ion rechargeable cell
may cause leakage, heat, smoke, an explosion, or fire, capacity decreasing.
! Warning
Strictly prohibit put cell into a microwave oven, dryer, or high-pressure container.
Strictly prohibit use cell with dry cells and other primary batteries, or new and old battery or batteries
of a different package, type, or brand.
Stop charging the Cell if charging is not completed within the specified time.
Stop using the Cell if abnormal heat, odor, discoloration, deformation or abnormal condition is
detected during use, charge, or storage.
Keep away from fire immediately when leakage or foul odor is detected.
If liquid leaks onto your skin or clothes, wash well with fresh water immediately.
If liquid leaking from the Cell gets into your eyes, do not rub your eyes. Wash them well with clean
flowing water and go to see a doctor immediately.
! Caution
Before using the Cell, be sure to read the user’s manual and cautions on handling thoroughly.
Charging with specific charger according to product specification. Charge with CC/CV method.
Strictly prohibit revered charging. Connect cell reverse will not charge the cell. At the same time, it
will reduce the charge-discharge Performance and safety Performance; this will lead to product heat
and leakage.
Store batteries out of reach of children so that they are not accidentally swallowed.
If younger children use the Cell, their guardians should explain the proper handling.
Before using the Cell, be sure to read the user’s manual and cautions on handling thoroughly.
Batteries have life cycles. If the time that the Cell powers equipment becomes much shorter than usual,
the Cell life is at an end. Replace the Cell with a new same one.
When not using Cell for an extended period, remove it from the equipment and store in a place with
low humidity and low temperature.
While the Cell pack is charged, used and stored, keep it away from objects or materials with static electric
charges.

If the terminals of the Cell become dirty, wipe with a dry clothe before using the Cell.
Storage the cells in storage temperature range as the specifications. After full discharged, we suggest
that charging to 3.6~3.9V with no use for a long time.
Battery should be charged and discharged every 3 months at 0.2 C during long term storage, and then
charge to 50-70% of the capacity for storage.
Do not exceed these ranges of the following temperature ranges：
Charge temperature range: 0℃ ～ 45℃
Discharge temperature range: -20℃ ～ 60℃
Storage temperature range(up to 30 days): -20℃～ +45℃
Storage temperature range(up to 90 days): -10℃～+35℃
! Special Notice
Keep the cells in 50% charged state during long period storage. We recommend to charge the
battery up to 50% of the total capacity every 6 months after receipt of the battery and maintain the
voltage 3.6~3.9V. And store the battery in cool and dry place.
EEMB reserves the final explanation. Please use battery strictly according to specification. EEMB will not be responsible for any
inappropriate operation. EEMB keeps the right to change product specifications without previous notice. If any question, please
