Charger Operation

Maintenance and Storage

MILWAUKEE battery packs will operate for

WARNING

many years and/or hundreds of cycles when they are maintained and used according to these instructions.

A battery pack that is stored for six months without being used will discharge itself. Charge the battery every six months even if it is unused to maximize battery life. Do not tape the trigger in the “ON” position and leave the tool unattended as this may discharge the battery to a point where it will no longer be able to recharge. Use a MILWAUKEE battery pack only until it no longer performs with the power and torque needed for your application.

Store your battery pack in a cool, dry place. Do not store it where the temperature may exceed 120°F (50°C) such as a vehicle or metal building during the summer. High temperatures will overheat the battery pack, reducing battery life. If it is stored for several months, the battery pack will gradually lose its charge. One to three cycles of charging and discharging through normal use will restore the capacity of the battery pack. Dur- ing the life of the battery pack the operating time between charges becomes shorter. If the operating time becomes extremely short after a proper charge, the usable life of the battery pack has been reached and it should be replaced.

To reduce the risk of explosion, never burn a battery pack even if it is damaged, dead or completely discharged.

RBRC Battery Recycling Seals

The RBRC™ Battery Recycling Seals (see "Symbology") on your tool battery packs indicate that MILWAUKEE has arranged for the recycling of that battery pack with the Rechargeable Battery Recycling Cor- poration (RBRC). At the end of your battery pack's useful life, return the battery pack to a MILWAUKEE Branch Ofﬁce/Service Center or the participating retailer nearest you. For more information, visit the RBRC web site at www.rbrc.org.

Disposing of NiCd Battery Packs

Nickel-Cadmium battery packs are recy- clable. Under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Dispose of your battery pack according to federal, state and local regulations.

WARNING

Charge only MILWAUKEE 18-28V Lithium-Ion battery packs and MILWAUKEE 18V NiCd battery packs in the MILWAUKEE Li-Ion/NiCd Bat- tery Charger. Other types of batter- ies may cause personal injury and damage.

When to Charge the Battery Pack For MILWAUKEE NiCd Battery Packs:

Charge your battery pack overnight before you use it for the ﬁrst time and then when your tool no longer performs with the power and torque needed for the job. Never com- pletely discharge the battery pack.

New battery packs reach full loading capac- ity after 2-10 chargings and dischargings. Battery packs which have not been used for some time should be recharged before use.

For MILWAUKEE Li-Ion Battery Packs:

Remove the battery pack from the tool for charging when convenient for you and your job. MILWAUKEE battery packs do not de- velop 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 bat- tery pack.

•You can "Top-Off" your battery pack's charge before starting a big job or long day of use.

•The only time it is necessary to charge the MILWAUKEE Lithium-Ion battery pack is when the pack has reached the end of its charge. To signal the end of charge, power to the tool will drop quickly, allowing you just enough power to ﬁnish making a cut, drilling a hole, or driving a fastener. Charge the battery pack as needed.

How to Charge the Battery Pack

Place the battery pack onto the bay by slid- ing the pack on from the top of the bay. The red light will come on, either ﬂashing (pack is too hot or cold) or continuous (pack is charging).

•For MILWAUKEE Li-Ion battery packs, the Fuel Gauge lights on the battery pack are displayed as the pack is being charged, indicating how fully charged the pack is.

•A fully discharged pack with an internal temperature in the normal range will charge in about an hour (For Li-Ion, between 32°F and 150°F; for NiCd, be- tween 32°F and 140°F). Heavily cycled battery packs may take longer to charge completely.

•After charging is complete, the con- tinuous green light will come on. For MILWAUKEE Li-Ion packs, the Fuel Gauge lights will go off. The Fuel Gauge button won't work when the pack is on the charger.

•The charger will keep the battery pack fully charged if it is left on the charger.

•If the light indicator flashes red and green, check that the battery pack is fully seated into the bay. Remove the pack and reinsert. If the light continues to ﬂash red and green, the battery pack may be extremely hot or cold, or wet. Allow the pack to cool down, warm up, or dry out and then reinsert. If the problem persists, contact a MILWAUKEE service facility.

•If the light indicator does not come on, check that the battery pack is fully seat- ed into the bay. Remove the pack and reinsert. If the light indicator still does not come on, contact a MILWAUKEE
