Lithium Ion Batteries should remain in a device or a safe nonconductive battery case when not charging.
DO NOT expose any battery to water, extreme heat, or carry in your pocket, purse, etc while not in a device or battery case.
Contact with metal such as keys and change can result in venting.
DO NOT remove the wrap off of a battery for any reason.
Discontinue use of any battery that has corrosion, bulging, damaged wrap, etc. or has been exposed to water or extreme heat, immediately.
Discontinue use of any device that is "auto firing" immediately.
Always follow safe battery handling and charging instructions.
Misuse or mishandling of lithium ion batteries can cause battery venting and explosion and can/will result in bodily harm.
