Safety
▶ Batteries must not be modified or tampered with!
▶ Never use recycled or repaired batteries conducted by non-Hilti companies.
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. Examine your batteries regularly for signs of damage, such as shredding, cuts
or punctures.
▶ Never use the battery or a battery-operated power tool as a hammer.
▶ Avoid eye or skin contact with leaking liquids!
▶ See What to do in case of damaged batteries
▶ Damaged batteries can leak fluid which may moisten adjacent objects. Clean these objects with warm
soapy water and replace the damaged batteries.
▶ See What to do in case of damaged batteries
▶ Never expose batteries to elevated temperature, sparking, or an open flame because the battery may
explode.
▶ Do not touch the battery poles with your fingers, tools, jewelry, or other metallic objects because this
may cause a short circuit, electrical shock, burns or explosions.
▶ Keep batteries away from rain or moisture. Penetrating moisture can cause short circuits, electrical
shock, burns or explosions.
▶ Only use chargers and power tools approved for the specific battery type. Read and follow the instructions
in the respective user manuals.
▶ Do not store or use the battery in explosion-prone environments containing combustible liquids or gases.
An unexpected battery malfunction can cause an explosion under those conditions.
What to do in case of damaged batteries
▶ If a Hilti battery is found to be damaged, contact your Hilti service partner.
▶ If a battery is leaking, use safety goggles and gloves to avoid direct eye or skin contact.
▶ 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, close 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. Do not ship or mail damaged batteries!
▶ Use a chemical spill cleanup kit to remove leaked battery fluid.
What to do in case of dysfunctional batteries
▶ Watch for abnormal battery behavior, such as faulty charging or unusually long charging times, noticeable
power loss, unusual charger LED activity, or leaking fluids. These are signs of an internal problem.
▶ If you suspect an internal battery problem, contact your Hilti service partner.
▶ Should the battery be in operational or no longer chargeable or leaking fluid, dispose of it as described
above.
▶ See What to do in case of damaged batteries.
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.
▶ Battery fires should be extinguished with water. Powder fire extinguishers and fire blankets are ineffective
with Li-Ion batteries. Fires started by a lithium-ion battery in nearby materials can be extinguished with
any appropriate extinguishing agent.
▶ Do not try to move large quantities of damaged, burning, or leaking batteries. Instead, remove surrounding
materials and isolate the batteries. If the scale of the fire is larger than can be extinguished with available
methods, contact the nearest firefighting authority.
In the case of a single 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.
▶ Wait for the battery to cool down completely.
