Battery Disposal

Battery Disposal


NOTE - All of the information on this page is for the disposal of US Government Owned Batteries at the Naval Postgraduate School ONLY.  Contractor and Personally owned batteries are NOT allowed to be accumulated or disposed of on campus. 



Did You Know...

It is illegal to throw away common batteries in California. Under the California Universal Waste Rule, batteries can no longer be disposed of in the trash because they contain toxic metals such as mercury, lead, cadmium, and nickel. Batteries that end up in landfills may have a negative effect on our environment and food chain, potentially causing serious health risks to humans and animals.



Disposal Procedures for Office Batteries: 

Plastic Battery Accumulation Buckets have been provided by the installation Hazardous Waste Program Manager through out campus.  All Office Batteries (AAA, AA, C, D, Button Cell, 9-Volt, etc.) need to be disposed of in these buckets.  


All battery buckets need to remain secured with the lid except when batteries are being added.

Disposal Procedures for all Other Battery Types:

Contact your Department's Hazardous Material (HAZMAT) Representative for proper procedures for turning in used batteries. If NPS OSHE/Safety Office-approved manufacturer core return programs are available, this purchase pathway can be considered as the first option.


If you do not know who your Departmental HAZMAT Representative is, then contact the NPS Safety Office by email at .


Additional Note Regarding Lithium Batteries:

Many Lithium Battery manufacturers recommend disposal of the packs by draining them to the lowest possible voltage you can get at a discharge rate of C/10 or less, then puncturing the cells and dropping them into a saltwater mix in a non-metallic container. However, if the cells are not sufficiently drained, the act of puncturing the cells can cause ignition. Because of this, most manufacturers no longer recommend this disposal technique, and it is not authorized for NPS users.
