4. Warning in handling the lithium-ion cell
To prevent the possibility of the cell from leaking, heating, explosion, please observe the following
precautions:
Don’t immerse the cell in water;
Don’t use and leave the cell near a heat source such as fire or heater;
When charging, use a cell charger specifically for that purpose;
Don’t reverse the positive and negative terminals;
Don’t discard the cell in fire or heater;
Don’t connect the cell to an electrical outlet directly;
Don’t discard the cell in fire or heater;
Don’t connect the positive and negative terminal directly with metal objects;
Don’t transport and store the cell together with metal objects such as necklaces, hairpins;
Don’t directly solder the cell;
Don’t pierce the cell with a nail or other sharp object.
5.Shipping
The capacity of delivery battery is approximately at 50% of charging. During transportation , keep the battery from acutely vibration, impacting, solarization, drenching.
