Hilti Li-ion batteries
Instructions for safety and useThis documentation uses the term battery to describe rechargeable Hilti Li-ion battery packs containing several Li-ion cells joined together. These batteries are to be used in Hilti power tools exclusively. Use only genuine Hilti batteries!DescriptionHilti batteries have cell-management and cell-protection systems.
The batteries are composed of cells that contain lithium-ion storage materials capable of providing high specific energy density. Li-ion cells have a minimal memory effect, but they are very susceptible to external impact, deep discharge, and high temperatures.
The products approved for use with Hilti batteries can be found in your Hilti Store or at: www.hilti.group

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 .
- 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!
- 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 .
- 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.

Comply with the locally applicable regulations for transporting batteries.
- Keep the battery free of oil and grease. Do not permit dust or dirt to accumulate unnecessarily on the battery. Clean the battery with a dry, soft brush or a clean, dry rag.
- Never use a battery with clogged ventilation slots. Clean the ventilation slots carefully using a dry, soft brush.
- Prevent unnecessary exposure of the battery to dust or debris and never subject the battery to soaking moisture (e.g., submerged in water or left out in the rain).
- If a battery is exposed to soaking moisture, treat it as a damaged battery and isolate it in a non-flammable container.
- See the section headed What to do in case of damaged batteries .
- Improper disposal may cause health hazards from leaking gases or fluids. Dispose of the battery 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!
- Do not dispose of batteries as household waste.
- Dispose of your battery out of the reach of children. Cover the terminals with a non-conductive material (such as electrical tape) to prevent short circuiting.
