Do not dismantle, cut, open, crush, bend, deform, puncture,
or shred cells or batteries. In the event of a battery leak, do
not allow the liquid to come in contact with the skin or
eyes. In the event of such a leak, flush your skin or eyes
immediately with water, or seek medical help.
Do not modify, remanufacture, attempt to insert foreign
objects into the battery, or immerse or expose it to water or
other liquids.
Improper battery use may result in a fire, explosion, or other
hazard. If the device or battery is dropped, especially on a
hard surface, and you believe the battery has been
damaged, take it to a service center for inspection before
continuing to use it.
Use the battery only for its intended purpose. Never use any
charger or battery that is damaged. Keep your battery out of
the reach of small children.
