Alkaline electric tape at both ends, lithium in a metal box with the contacts taped as well until i can get them recycled. Spicy pillows in a bucket with sand. Not sure how safe I am but I think its better than nothing
Most supermarkets in the UK have battery recycling bins, and they're not uncommon in France and Germany. I've been systematically replacing all my batteries with rechargeable the past few years, though, and I encourage other to do the same.
The regular alkalines just go in the trash, but I try to avoid those when possible for rechargables. Everything else is in a fireproof battery bag. Apparently there's only 1 day a year where we can recycle them here. I can't imagine everyone is doing that. I should probably just landfill it like everyone else.
Having to hoard batteries for a year on the hopes of seeing the notice, being free, and able to travel across town for that those few hours a year is kind of a big ask. I still have lithium batteries I've been trying to get rid of for like 5 years now.
