Battery Operation

Fuel Gauge

Compared to NiCd battery pack types, MILWAUKEE Li-Ion battery packs deliver fade-free power for their entire run time. The tool will not experience a slow, gradual loss of power during use.

Use the fuel gauge to determine the battery pack's remaining run time. Press the fuel gauge button to display the lights. The fuel gauge will light up for 2-3 seconds.

Approximate Run Time Remaining:

• 78-100%
• 55-77%
• 33-54%
• 10-32%
• Less than 10% (if bottom light is flashing)

To signal the end of discharge, 1 light on the fuel gauge will flash quickly for 2-3 seconds and the tool will not run. Charge the battery pack.

An alternating blinking pattern indicates that an error or overtemperature state was encountered. Allow the battery pack to cool and reinsert. If the pattern continues, contact a MILWAUKEE service facility. If the fuel gauge doesn't appear to be working, place the battery pack on the charger and charge as needed.

Immediately after using the battery pack, the fuel gauge may display a lower charge than it will if checked a few minutes later. The battery cells "recover" some of their charge after resting.

Battery Pack Protection

To protect itself from damage and extend its life, the battery pack's intelligent circuit monitors current draw and temperature. In extremely high torque, binding, stalling, and short circuit situations, the battery pack will turn OFF the tool if the current draw becomes too high. All the fuel gauge lights will flash. Release the trigger and restart.

Under extreme circumstances, the internal temperature of the battery could become too high. If this happens, the fuel gauge lights will flash in an alternating pattern and the product will not run. Allow the battery to cool down.

Fuel Gauge Lights Diagnosis and Solutions

Cold Weather Operation

MILWAUKEE Li-Ion battery packs are designed to operate in temperatures below freezing. When the battery pack is too cold, it may need to warm up before normal use. Put the battery on a product and use the product in a light application. It may "buzz" for a short time until it warms up. When the buzzing stops, use the tool normally.

Transport

The regulations pertaining to the transport of Li-Ion batteries are affected by whether the battery is transported in a personal vehicle or offered for shipment via a commercial carrier. Always ship Li-Ion batteries in accordance with the current regulations governing the chosen mode of transport (e.g. ground, air, sea). When in doubt, contact MILWAUKEE, the carrier or other trained Dangerous Goods professional to determine applicable regulations.

The personal transport of Li-Ion battery packs is allowed when done in accordance with these warnings and instructions. When shipping Li-Ion batteries with a commercial carrier, they are shipped under classification UN 3480 (battery only) or UN 3481 (batteries contained in or packed with equipment). The proper packaging, labeling, marking, and documentation requirements are generally dependent upon whether the particular batteries are rated greater than or less than 100 Wh. Often, Li-Ion batteries rated 100 Wh or less are "excepted" from certain shipping regulations. In the U.S., products shipped via ground transport may be "excepted" from certain hazardous material shipping regulations if they are under 300Wh.

Disposing of MILWAUKEE Li-Ion Battery Packs

MILWAUKEE Li-Ion battery packs are more environmentally friendly than some other types of battery packs (e.g., nickel-cadmium). Always dispose of battery packs according to federal, state and local regulations. Contact a local recycling agency for recycling locations.

⚠️ WARNING: To reduce the risk of injury or explosion, never burn or incinerate a battery pack even if it is damaged, dead, or completely discharged. When burned, toxic fumes and materials are created.

Even discharged battery packs contain some energy. Before disposing, use electrical tape to cover the terminals to prevent the battery pack from shorting, which could cause a fire or explosion.

RBRC Battery Recycling Seals

The RBRC™ Battery Recycling Seals (see the Symbology section) on battery packs indicates that MILWAUKEE has arranged for recycling with the Rechargeable Battery Recycling Corporation (RBRC). At the end of its useful life, return the battery pack to a MILWAUKEE Branch Office/Service Center or a participating retailer. For more information, visit the RBRC web site at www.rbrc.org.

Charger Operation

⚠️ WARNING: Charge only MILWAUKEE M18™ and M12™ Li-Ion batteries in this MILWAUKEE Li-Ion charger. Other types of batteries may cause personal injury and damage.

When to Charge the Battery Pack with this MILWAUKEE Charger

Remove the battery pack from the product for charging when convenient for you and your job. MILWAUKEE batteries do not develop a "memory" when charged after only a partial discharge. It is not necessary to run down the battery pack before placing it on the charger.

• Use the fuel gauge to determine when to charge your MILWAUKEE Li-Ion battery pack.
• The battery pack's charge can be "Topped-Off" before starting a big job or long day of use.
• The only time it is necessary to charge the MILWAUKEE Li-Ion battery pack is when the battery pack has reached the end of its charge. To signal the end of charge, power to the product will drop quickly, allowing enough power to finish the operation. Charge the battery pack as needed.

How to Charge the Battery Pack

Align the battery pack with the bay and slide the battery pack into the charger as far as possible. The red light will come on, either flashing quickly (battery pack or charger is too hot or cold), flashing slowly (communication between pack and charger) or continuous (pack is charging).

• Charge time depends on capacity of battery pack. Heavily cycled batteries may take longer to charge completely.
• On M18™ battery packs, the fuel gauge lights are displayed as the pack is being charged, indicating how fully charged the pack is. The fuel gauge will turn off when charging is complete.
• After charging is complete, the continuous green light will come on.
• The charger will keep the battery pack fully charged if it is left on the charger. The light indicator will be same as normal charging.
• The next pack inserted in the charger will begin charging when the previous pack is fully charged.
• If the light indicator flashes red and green or does not come on, check that the battery pack is fully seated into the bay. Remove the battery pack and reinsert. If the problem persists, remove pack(s) and unplug charger for at least 2 minutes. After 2 minutes, plug charger back in and insert pack. If the problem continues, contact a MILWAUKEE service facility.

Charging a Hot or Cold Battery Pack

The charger has advanced electronics that adjust the charge rate based on battery temperature. Hot or cold batteries may take longer to charge. When the battery pack temperature is outside the normal charging range, the red light will flash and the battery will not charge. Once the battery pack is within the acceptable range, normal charging will take place and the red light will be continuous. This optimizes charge time and battery life.

Powering the Charger with an Inverter or Generator

The charger will operate with most generators and inverters rated at 350 Watts or higher.

Mounting to the Wall

Use the wall mount guides to mark the hanging points.

Maintenance

⚠️ WARNING: To reduce the risk of fire, personal injury, and product damage due to a short circuit, never immerse a tool, battery pack or charger in fluid or allow a fluid to flow inside them. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, and bleach or bleach containing products, etc., can cause a short circuit.

Always unplug the charger and remove the battery from the charger before performing any maintenance. Never disassemble the battery or charger. Contact a MILWAUKEE service facility for ALL repairs.

Do not expose battery packs, chargers or tools to fluids, water, or rain, or allow them to get wet. This could damage the tool, charger, and/or battery pack. Clean out dust and debris from tool, charger and battery vents and electrical contacts by vacuuming or brushing. Clean housings with a damp, soapy cloth, keeping away from all electrical contacts. Certain cleaners and solvents, such as gasoline, turpentine, lacquer thinner, paint thinner, bleach, chlorinated cleaning solvents, ammonia and household detergents containing ammonia, are harmful to plastics and other insulated parts; plastic casings will become brittle and crack. Never use flammable or combustible solvents around batteries, charger, or tools.

Storage

As a general practice, it is best to unplug chargers and remove battery packs when not in use, however, no damage to the battery pack will occur. Store at room temperature away from moisture. Store batteries upright. Do not store in damp locations where corrosion of terminals may occur. Storing in high temperatures (over 120°F) for long periods can result in permanent capacity loss for any battery. Charge before use after storing for long periods.

Repairs

No serviceable parts.
