Used Batteries

Back to Types of Waste Disposals At SFSU

Used batteries are waste electrochemical cells that contain hazardous substances such as lead, lithium, cadmium, and mercury. These substances pose risks to human health and the environment if released. Batteries are classified as Universal Waste under federal and California regulations and must be managed with care to prevent leaks, short circuits, or fire hazards.

Characteristics of Waste Batteries:

  • Contain corrosive or toxic components.
  • May leak if damaged or improperly stored.
  • Some types (especially lithium) are reactive or flammable.
  • Can pose fire or explosion risks if terminals are shorted.

Wastes Batteries information

  • Alkaline batteries (AA, AAA, C, D, 9V).
  • Lithium-ion (Li-ion) rechargeable batteries (from laptops, phones, tools).
  • Nickel-cadmium (Ni-Cd) and nickel-metal hydride (NiMH) batteries.

  • Full containers should be transferred promptly to SFSU’s central Universal Waste storage
    site.

Who Removes the Waste:
Trained personnel from EH&S or Facilities collect battery waste on request.

Where It Is Taken:
All waste batteries are consolidated in the Universal Waste storage area within the university's hazardous waste management facility

  • Batteries are picked up on a quarterly basis, or more frequently if volume requires.
  • Emergency pickups are arranged for damaged, leaking, or bulging batteries
  • Batteries are transported by a certified Universal Waste recycling contractor.
  • Processing includes:
    o Metal recovery (nickel, cadmium, lead, lithium, cobalt).
    o Neutralization and stabilization of hazardous components.
    o Proper recycling or disposal of non-recoverable materials.
  • All disposal and recycling activities follow EPA (40 CFR 273) and California Title 22 guidelines.
