- Home security cameras recorded an e‑bike lithium‑ion battery burst into flames that blew open the garage door and sent thick smoke into the living area, footage released after the early‑morning incident on Tuesday, May 26.
- Ann Arbor firefighters found two cats inside the home, treated one with oxygen at the scene, and transported both to a local emergency veterinary hospital for further care.
- The Ann Arbor Fire Department said the battery was not charging when it ignited and described the owner as having followed proper procedures, while crews pointed to thermal runaway as the cause.
- Safety experts and the National Fire Protection Association reiterated guidance to buy certified batteries and chargers, charge devices singly at room temperature, store batteries away from exits and flammable items, and recycle batteries through proper channels rather than discarding them in household trash.
- The incident highlights how home security systems can warn absent residents and provide crucial visual evidence for emergency response, and it may prompt more homeowners to review e‑bike charging, storage, and disposal habits.
