Safety: Battery
• Use only DellTM battery modules that are approved for use with this battery charger. Use of other types
may increase the risk of fire or explosion.
• Do not carry a battery pack in your pocket, purse, or other container where metal objects (such as car
keys or paper clips) could short-circuit the battery terminals. The resulting excessive current flow can
cause extremely high temperatures and may result in damage to the battery pack or cause fire or burns.
• The battery poses a burn hazard if you handle it improperly. Do not disassemble it. Handle a damaged
or leaking battery pack with extreme care. If the battery is damaged, electrolyte may leak from the cells
and may cause personal injury.
• Keep the battery away from children.
• Do not store or leave your computer, battery pack, or battery charger near 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 60°C (140°F). When heated to excessive temperatures, battery cells could
explode or vent, posing a risk of fire.
• Do not dispose of your battery in a fire or with normal household waste. Battery cells may explode.
Discard a used battery according to the manufacturer's instructions or contact your local waste disposal
agency for disposal instructions. Dispose of a depleted or damaged battery promptly.
