Hilti Li-Ion Battery
Instructions for safety and use
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
- Comply with the following safety instructions for the safe handling and use of Li-ion batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
- Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely harmful to health!
- Do not under any circumstances modify or tamper with batteries!
- Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
- Never use or charge a battery that has suffered an impact or been damaged in any other way. Check your batteries regularly for signs of damage.
- Never use recycled or repaired batteries.
- Never use the battery or a battery-operated power tool as a hammer.
- 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
- 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.
- 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 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.
- Store batteries in a cool and dry place. Cool storage will increase battery life. Never store batteries where they are exposed to direct sunlight, on sources of heat or behind glass.
- Do not send batteries through the mail. Consult your shipper for instructions on how to ship undamaged batteries.
- Never transport batteries in bulk form (loose, unprotected). During transport, batteries should be protected from excessive shock and vibration and isolated from any conductive materials or other batteries that may come in contact with the terminals and cause a short circuit. Comply with the locally applicable regulations for transporting batteries.
Maintenance and disposal
- 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 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.
