Warning in handling the lithium-ion cell
To prevent the possibility of the cell from leaking, heating, or 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
Shipping
During transportation, keep the battery from acute vibration, impacting, polarization, and drenching.
Application
Electric wheelchairs, electric power systems, solar energy storage systems, uninterruptible power supplies, household appliances, ships, electric bicycles/scooters, consumer electronics, golf carts, electric vehicles, power tools, submarines, electric forklifts.
