Option 1: Mail Services

Send used batteries through campus mail for disposal? When all the following are true, yes!

  • You are located on campus or at SIO (La Jolla)
  • You do not have a Waste Generator Number
  • The batteries are not leaking or corroded
  • The package weighs less than 2 pounds
    (if it weighs more than 2 pounds, use option 2)

How to do it:

  • Cover the terminals with plastic nonconductive tape (Scotch® tape or electrical tape) to prevent the possibility of spark.
  • Place the batteries in a sturdy bag or container. Limit the package weight to 2 pounds or less.
  • Address the package to "Used Batteries" at Mail Code 0958.

Note: Due to regulatory restrictions, only campus and SIO (La Jolla), UCMC Hillcrest, and Thornton Hospital may send used batteries through mail services.

Option 2: Request hazardous waste pickup

Request a hazardous waste pickup if a battery weighs more than 2 pounds.

How to do it:

  • E-mail a request for pickup to hazwaste@ucsd.edu.
  • Include this information:
    • Your name
    • Phone number
    • The quantity of batteries
    • Building
    • Room number where the batteries are located
