How to dispose of old CR123 batteries?

Hi All,
So I haven't been active on the forum for many years. I recently dug back into my crazy collection from my active days and I probably have 50+ old, dead CR123 and cr2 cells. I searched online, as well as this forum, and cannot find much recent guidance on disposal. Alkalines pretty much are straight into the garbage, and rechargeables are taken by several places..but nothing on single use lithium

What are you guys doing with your cells?

Thank you

Personally, I'd just toss 'em. They do contain lithium metal, though I'm not sure it's still active if they're dead. Perhaps it's already oxidized, which means it won't burn? You could take them to your local hazardous waste depot, and they can toss 'em.

These cells have a really long shelf life and are probably still good long after their expiration date so it may be worth while to check them before you get rid of them.

I think you can toss them in the trash, though you probably should check with the local authorities in charge of trash collection. I would soak them in a pail of salty water for a day or two just to make sure they are fully drained and won't short out in the trash.

So I haven't been active in a really long time...the cells expired years ago, but to be certain, I used my ZTE pulse load tester, and the majority didnt register, and some were like 10%.

I put a small piece of tape on the positive end, rubber band them together in a ziplock and recycle them at batteries and bulbs or Home Depot.

Take them to your local Lowe's store and drop them in the battery recycling station at the exit/entrance.

Lowes as well as home depot only claim to take rechargeables on their website. No provisions for disposable lithium ion... Bummer.

Los Angeles County requests that we tape the positive end of cells before handing them off to a local hazardous waste collection center or a designated county library. Check your local programs.

Lithium batteries, even completely discharged, are a source of poisonous pollution, when the outer shell is broken due to corrosion or mechanical stress, it will begin to slow kill everything around. If there is any torment of conscience, then they must be handed over to the local supermarket, where there are waste bins for collecting batteries. As far as I know, all types of batteries are now being recycled, either for fertilizers, or for metal, or for new batteries. On the other hand, if thrown away, your contribution to the pollution of the planet is nothing compared to industrial plants and car exhaust, so you can also sleep peacefully
