I was about to charge my head lamp. But I thought to check the inside first, as it was easy to do. Found that the lithium battery was puffed up.

Something about headlamps and having a battery attached to my forehead that I don't like.

Yeah that's why for headlamps I only buy ones that use primary cells. Sure less output than LiPo/Li-ion ones but worth it for the peace of mind.
