The presence of Li-ion batteries has increased in recent years, due to their light weight, high energy density, and long life span. Li-ion batteries can be found in laptops, power tools, and many other electric devices.

 While they can be a powerful energy source, Li-ion batteries pose many
safety risks due to their high energy density (high amount of energy in a small space) and flammable electrolyte. All Li-ion battery users must be aware of and equipped to deal with the hazards that the batteries may pose.

Poorly manufactured, overcharged, or incorrectly handled batteries can lead to an event called thermal runaway. Thermal runaway is a phenomenon in which a battery cell enters an uncontrolled, self-heating state, which can lead to venting, leaking, explosion and/or fire of the battery pack.

RECYCLING

Proper recycling of an old or damaged Li-ion battery is crucial. Improper disposal (depositing batteries into household trash/recycling) can cause
landfill fires, which can result in toxic chemicals being released into the air. Common, alkaline batteries can be disposed of as regular, household trash.

• La Crosse County residents can properly dispose of batteries for free using the Household Hazardous Materials Program.
• Terminal ends of intact batteries must be taped with clear tape to prevent arcing and stored in anon-metal container.
• Swollen or damaged batteries must be stored and transported in sand or kitty litter.
• Do not co-mingle any batteries with chemicals.
• Small businesses and organizations are asked to make an appointment and pay a fee for disposal.
• Out-of-County residents are welcome to use the program on a fee basis.
• Batteries can also be taken to Batteries Plus or Hilltopper Refuse and Recycling for a fee.
