Investigators say a lithium battery in an outdoor storage container started the fire that killed a 92-year-old woman at the Jersey Shore.
It happened early Friday morning in Stafford Township, Ocean County.
Two other people were able to escape.
Firefighters say you should only buy batteries that are listed by a nationally recognized testing laboratory, like UL. Take lithium batteries off the charger once they're fully charged, and don't keep them in places that are too hot or too cold.
