That's about three years of batteries I've used and accumulated over the years. Most of our daily-use devices are powered by rechargeable batteries, but clocks, LED closet lighting, and a few other units are powered by good ole copper tops. They eventually are retired and stored in a glass jar; I finally hit the top, so it's now time to properly dispose of these acid filled mini-hazardous waste containers properly instead of the trash can....
If you're disposing rechargeable batteries, good news, you can just walk into a Best Buy and drop them off into their tech recycling bins usually in the front entrance. But if you've a collection of single use dry cell batteries, you'll want to abide by your specific state laws (here in California, under the California Universal Waste Rule, household batteries are considered hazardous waste and cannot be put into the trash because of their mercury, lead, cadmium, and nickel content).
So where to go with your big bag of batteries? Here in Los Angeles, you might be surprised to find some County Public Library will take and properly dispose of batteries. There are also mobile Household Hazardous Waste Events alongside a permanent center operated by the City of Los Angeles.
Better yet, here are some retail stores and businesses which can take your batteries the next time you're shopping...or even getting your oil changed:
