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;

Don’t leave the cell with low SOC for long time, it should keep the cell with around 50% for long term storage (less than 6 months). Should charge the cell to 50% SOC after each 6 months.

 

Shipping
