SAFETY: Portable Device Battery Safety
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery
only with a compatible battery purchased from Dell that is designed to work with your computer. Do
not use a battery from other computers with your computer.
·
A damaged battery may pose a risk of personal injury. Damage may include impact or shock that dents or punctures
the battery, exposure to a flame, or other deformation. Do no disassemble the battery. Handle a damaged or leaking
battery pack with extreme care. If the battery is damaged, electrolyte may leak from the cells or fire may result
which may cause personal injury.
·
Keep the battery away from children.
·
Do not expose (store or place) your computer or battery pack to a heat source such as a radiator, fireplace, stove,
electric heater, or other heat-generating appliance or otherwise expose it to temperatures in excess of
70
0
C
(158
0
F). When heated to excessive temperatures, battery cells could vent or explode, posing a fire risk.
·
Do not carry a battery pack in your pocket, purse, or other container where metal objects (such as keys) could short-
circuit the battery terminals. The resulting excessive current flow can lead to extremely high temperatures and may
cause damage to the battery pack or surrounding materials, or personal injury, such as burns.
