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.
