Lithium batteries contain volatile materials such as lithium organic solvents and other chemical ingredients. Incorrect handling of lithium batteries may result in heat generation, fire or explosion, with the risk of personal injury or damage. To prevent accidents when handling batteries, be sure to observe the following precautions.
#1-Do Not Stack or Jumble Lithium Button Batteries
Avoid contact between positive (+) and negative (-) battery poles, and contact with other metal surfaces, as this can cause short circuits with intense current flows and heat. Stacking or jumbling batteries, as shown at right, may cause short circuits, heat generation, fire or explosion.
#2-Do Not Dispose of Lithium Button Batteries in Fire
Disposal of batteries in fire is extremely dangerous with a risk of explosion and violent flaring.
#3-Do Not Heat Lithium Button Batteries
When lithium batteries are hearted above 100℃（212℉）, the resin used in seals, separators and other parts may be damaged, causing electrolyte leaks and internal short circuits which may lead to fire or explosion.
#4-Do Not Solder Directly Onto Lithium Button Batteries
Heat from soldering may damage seals, separators and other parts, causing electrolyte leaks and internal short circuits which may lead to fire or explosion.
#5-Do not recharge lithium button batteries
Attempting to recharge batteries may result in internal generation of gases, which may lead to swelling, fire or explosion.
#6-Do not disassemble lithium button batteries
Do not disassemble lithium batteries as this can generate a gas that may irritate the throat. Lithium may also react with moisture to generate heat and fire.
#7-Do not deform lithium button batteries
When extreme pressure is applied to batteries, seals may be deformed or damaged, causing electrolyte leaks or internal short circuits. This may lead to the risk of heat generation, fire or explosion.
#8-Do Not Mix Different Types of Lithium Button Batteries
For some applications, mixing different types of batteries, or new and old batteries, can cause over discharge due to differences in voltage and electrical capacities, This may lead to the risk of swelling or explosion.
#9-Insert Lithium Button Batteries Correctly
Depending on the application device, incorrect insertion of batteries, with positive (+) and negative(-) poles reversed, may result in short circuits and the risk of heat generation, fire or explosion.
#10-Dispose of Used Lithium Button Batteries Correctly
Dispose of used batteries promptly according to local recycling or waste regulations .
