I recently replaced the battery on my ThinkPad, and the old battery is still in good shape—no swelling or cracks. However, I'm not sure how to properly dispose of it since there's no recycling center or official organization nearby in my country. I'm worried about just throwing it in the dumpster since animals might get to it, or it could crack. I've heard suggestions like soaking it in saltwater to discharge it, but my main concern is safe storage. Right now, it's packed away in a cardboard box in my cupboard, but I feel uneasy about that for long-term storage. Any advice would be really helpful!

If you don't have a safe disposal option nearby, keeping it in a closed barrel filled with sand is a solid temporary solution. It may sound strange, but it helps reduce the risk of fire hazards. You could definitely use a plastic container with sand too, just make sure it’s securely closed to prevent any accidents. Just remember to check on it occasionally so you don’t forget about it!
I get your concern! Storing it in a cardboard box isn't the best idea since it's not fireproof. Instead, if you can, just keep it in a well-ventilated, dry area, maybe in a sturdy container. If you ever get the chance, look up any local electronics stores; they sometimes take batteries for disposal. It’s better than just tucking it away for a long time.
