▶ Never use the battery or a battery-operated power tool as a striking tool.
▶ Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This
can lead to explosions.
▶ Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects.
This can damage the battery and also cause material damage and personal injury.
▶ Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits,
electric shock, burns, fire and explosions.
▶ Use only chargers and power tools approved for the specific battery type. Read and follow the relevant
operating instructions.
▶ Do not use or store the battery in explosive environments.
▶ If the battery is too hot to touch it may be defective. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Follow the instructions in the
section headed What to do in case of a battery fire.
What to do in case of damaged batteries
▶ Always contact Hilti when a battery is damaged.
▶ Never use a battery that is leaking fluid.
▶ Avoid direct eye and/or skin contact with fluid leaking from a battery. Always wear protective gloves and
eye protection when undertaking tasks involving battery fluid.
▶ Use a chemical spill cleanup kit to remove leaked battery fluid. Comply with the locally applicable cleanup
regulations for battery fluid.
▶ To store a damaged battery, place the battery in a non-flammable container and cover the battery with
dry sand, chalk powder (CaCO3) or silicate (Vermiculite). Then seal the lid air-tight and store the container
away from flammable gases, liquids or objects.
▶ Dispose of the container at your Hilti Store, or consult your local governmental garbage disposal or public
health and safety resources for disposal instructions. Comply with the locally applicable regulations
for transporting damaged batteries!
What to do in case of dysfunctional batteries
▶ Watch for abnormal battery behavior, such as faulty charging, unusually long charging times, noticeable
power loss, unusual LED activity, or leaking fluids. These are signs of an internal problem.
▶ If you suspect an internal battery problem, contact Hilti Service.
▶ A battery that no longer works, cannot be recharged or leaks fluid has to be disposed of correctly. See
the section headed Maintenance and disposal.
What to do in case of a battery fire
WARNING
Battery fire hazard! A burning battery releases hazardous and potentially explosive liquids and fumes that
can lead to corrosion injuries, burns or explosions.
▶ Wear your personal protective equipment when you tackle a battery fire.
▶ Provide sufficient venting to permit hazardous and potentially explosive fumes to escape.
▶ Leave the room immediately in case of intense smoke emission.
▶ Consult a doctor in case of any skin or respiratory irritation.
▶ Alert the fire service before you start tackling the fire.
▶ Use only water to tackle a battery fire and keep as far from the fire as effective extinguishing permits.
Powder fire extinguishers and fire blankets are ineffective with Li-ion batteries. Fire in nearby materials
can be extinguished with appropriate extinguishing agents.
▶ Do not try to move large quantities of burning batteries. Instead, isolate the batteries by removing
unaffected materials from the immediate vicinity.
In the case of a battery that does not cool down, or a smoking or burning battery:
▶ Scoop the battery up with a shovel and drop it into a bucket of water, which will reduce the risk of igniting
adjacent cells that have not yet reached run-away temperature.
▶ Leave the battery in the bucket for at least 24 hours until it has cooled down completely.
▶ See the section headed What to do in case of damaged batteries .
Shipping and storage
▶ Ambient operating temperature to be kept between -17°C and +60°C / 1°F and 140°F.
▶ Storage temperature to be kept between -20°C and +40°C / -4°F and 104°F.
▶ Do not store batteries on the charger. Always remove the battery from the charger when the charging
operation has completed.
