Ly need help (ticking bomb)?

My sister has had a "round" laptop for some time. She didn't know why, neither did I. Examine the thing and could physically exclude the damage (fall / fall ect)

I decided to open the thing very carefully and found that the device or battery is about to explode…

My question: How should you dispose of it? And who do you turn to? I don't turn it on the garbage can because I don't want to be responsible if the beginnings burn or harm people.

Thanks for your tips.

PS: I called the fire brigade, they said I should put him in the fridge, but after 1 hour it was still bloated. And no idea where to put it.

Electronics retailers must accept and dispose of them. It is best to keep it in a fire-proof container with a lid until you can hand it over.

Will be the lithium battery. Would first put the laptop in a safe fire-proof place and then dispose of the battery. https://www.umweltbundesamt.de/umwelttipps-fuer-den-alltag/elektrogeraete/lithium-batterien-lithium-ionen-akkus

According to the Internet, you can hand these things over to recycling centers. Alternatively at the dealer. If necessary, you can call your Saturn, media market, whatever and ask if they will accept the battery.

Believe me lithium is so poisonous, they don't want the battery…

Don't want to, but have to. Anyone who trades in devices or batteries must also accept them and dispose of them properly. There are laws to prevent this understandable reluctance. And you don't have to tell me how great things are. In addition to other batteries and accumulators, I sold and shipped them on a large scale for two years. There was a shelf flying around our ears more than once.

Specialized trade,

Best kept in something fireproof. If it starts to burn, DO NOT try to extinguish it with water as please call the fire department immediately. Because with metal fires is not to be joked.
