I just got a new tenant in my rental house and this time I had to add a clause to the lease enumerating brands of lithium-ion batteries the tenant is allowed to keep on the premises. These things are basically grenades that you can buy for $2 on Temu. Stronger regulations needed.

Won't help much. Way too much cheap lithium ion crap with incapsulated batteries is flooding the markets

Yes, especially wearables and toys. Those are a real problem. One of my kids was gifted a toy that had an embedded Lithium Ion pouch battery of spectacularly bad quality, the pouch had already inflated to the point that it was unsafe to dispose of when he got it. I ended up hand delivering the whole thing to the local disposal site where they have the proper gear to deal with these.
