We are expanding the instructions and warnings to inform users of potential risks when highly conductive or corrosive fluids enter the M18 HIGH DEMAND 9.0 battery pack.

You do not need to return any of the instructions or warnings that accompanied your M18 HIGH DEMAND 9.0 battery pack. You simply need to get a copy of the expanded warnings and instructions and read them. You can download them here: www.milwaukeetool.com/expandedinstructions.

While these expanded warnings and instructions are currently directed to the M18 HIGH DEMAND 9.0 battery pack, the same caution should be taken by users of all battery packs and cordless and corded power tools, regardless of manufacturer, to avoid exposing the products to conductive or corrosive fluids. This exposure can degrade the performance and life of any battery pack or tool.

The quantity necessary to cause a failure within the pack can vary depending on the type of fluid, so you should take such steps as are appropriate given your conditions of use to avoid allowing these types of fluids to get into the pack. This warning is not intended to communicate that you should avoid using the M18 HIGH DEMAND 9.0 battery pack in areas where these types of fluids are present or being used; it means you should avoid letting these fluids get inside the pack. You should not attempt to open the battery pack to determine if these types of fluids got inside. If you believe highly conductive or corrosive fluids have entered your M18 HIGH DEMAND 9.0 battery pack, immediately call us at: 1-800-SAWDUST (7:00am - 10:00pm Eastern time Sunday - Saturday).

Rainwater is typically not a highly conductive or corrosive fluid. However, rainwater may still degrade the performance and life of your M18 HIGH DEMAND 9.0 battery pack. In an abundance of caution, we recommend disconnecting the M18 HIGH DEMAND 9.0 battery pack from any tool or charger and call us at: 1-800-SAWDUST (7:00am - 10:00pm Eastern time Sunday - Saturday) to receive further instructions.

You don't need to figure it out. If you have an M18 HIGH DEMAND 9.0 battery pack, to make sure you have the most up-to-date warnings and instructions, download them here: www.milwaukeetool.com/expandedinstructions and read them.

No. There is nothing wrong with your M18 HIGH DEMAND 9.0 battery pack. Its usage needs you to follow the expanded warnings and instructions on the proper use of the battery. You should obtain and follow the expanded instructions and warnings, available here: www.milwaukeetool.com/expandedinstructions, to ensure safe handling and operating.

You should not attempt to open the battery pack to determine if any fluids got inside. If you do not know whether any fluid entered into your M18 HIGH DEMAND 9.0 battery pack or if you do know, but do not recall whether the fluid was highly conductive or corrosive, immediately call us at: 1-800-SAWDUST (7:00am - 10:00pm Eastern time Sunday - Saturday).

No. These expanded instructions and warnings do not mean that you should avoid using the M18 HIGH DEMAND 9.0 battery pack in areas where highly conductive or corrosive fluids are present or being used. Rather, you should avoid those situations where the M18 HIGH DEMAND 9.0 battery pack is exposed to highly conductive or corrosive fluids that are likely to result in the fluids getting inside the battery pack. For example, if you are working on a pier over the ocean, avoid setting your M18 HIGH DEMAND 9.0 battery pack in a puddle of seawater. You should also avoid using your M18 HIGH DEMAND 9.0 battery pack in a manner where it could be engulfed by a wave of seawater or repeatedly splashed. These are not exhaustive examples. If you are unsure of your particular situation, please call us at 1-800-SAWDUST (7:00am - 10:00pm Eastern time Sunday - Saturday).
