Batteries
- Universal waste standards: Applies to all batteries.
- Lead-acid battery exclusion: Applies to lead-acid batteries only.
Businesses must ensure that they:
- Properly store batteries. Batteries stored unsafely can start a fire (such as lithium-ion batteries) or leak chemicals (mercury, lead, cadmium, lithium, or sulfuric acid).
- Never put batteries in the trash.
- Dispose of batteries correctly. Use a facility equipped for battery recycling.
If a business chooses not to manage batteries as universal waste or under the lead-acid battery exclusion, they must designate and manage them according to the Dangerous Waste Regulations (Chapter 173-303 WAC).
If you are a household or individual, do not put batteries in curbside recycling bins or trash. Find a household hazardous waste site, Call2Recycle, or 1-800-Recycle.
How to manage batteries as universal waste
Print or make your own universal waste label.
To manage batteries as universal waste:
- Store them in containers compatible with battery waste. Keep closed if the batteries show evidence of leaks, spills, or damage that could cause the battery to leak.
- Label containers as: "Universal Waste—Battery(ies)" or "Waste Battery(ies)" or "Used Battery(ies)."
- Track accumulation time by marking containers or through shipment records. Universal waste has a one-year time limit for on-site accumulation.
- Determine your handler category. Large quantity universal waste handlers are subject to additional rules.
- Recycle. Universal waste handlers are prohibited from disposing of universal waste.
ALL batteries can be managed as universal waste. There are no size or battery chemistry limitations.
How to manage batteries under the lead-acid battery exclusion
If you reclaim or regenerate spent lead-acid batteries, you can manage them under the lead-acid battery waste exclusion (WAC 173-303-520). The exclusion requires that you:
- Recycle your lead-acid batteries.
- Store them properly on-site.
- Meet all other requirements noted in the exclusion.
Battery storage tips
Follow these recommended best management practices to improve workplace safety:
- Separate batteries by type. Some recyclers will not accept containers of mixed waste batteries.
- Don’t mix used with new batteries. This may result in more waste generation.
- Don’t attempt to recharge a battery unless it’s marked as rechargeable. This could cause damage or rupturing.
Tips for lithium-based battery storage
- Cover the terminals of waste lithium batteries or place them in separate plastic bags to reduce the potential for fires.
- Store lithium batteries in a dry environment, away from heat sources and direct sunlight.
