Cautions

(1) Do not immerse the battery in water, and keep the battery in a cool dry surrounding if it stands by.

(2) Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.

(3) Do not reverse the position and negative terminals.

(4) Do not connect the battery electrodes to an electrical outlet.

(5) Do not short circuit. Otherwise it will cause serious damage of the battery.

(6) Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.

(7) Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.

(8) Please use special lithium charger.
(9) It should be noted that the cell would be possible to be at a over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain about 13.2V(Recommended 3 months one cycle).Over-discharging may causes loss of cell performance, characteristics, or battery functions.
(10) Do not disassemble battery.

Package

Battery will packed with small box then put into cartons.
We will ship the battery by express such as DHL, TNT, UPS, FEDEX etc. We can also ship by sea or air transportation for bulk large order.
Delivery time for production will depend on the quantity. Usually it will take 15-20 working days, the sample will be shipped out within 7-10 working days
