A family pet in Oklahoma has had a dog of a day when playtime sparked an emergency response. A pet monitoring camera captured the pup chewing on a power bank before a bright flash and a fire ignited. The two dogs and the cat inside the home managed to get out safely via the perfect escape hatch.
I just shared that article yesterday from iFixit about how to keep batteries from bloating during storage. An additional point might be to keep it away from creatures that might chew on them.
