7. Battery Charger
Charge only MILWAUKEE M18™ 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 tool 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.
• 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 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 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
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 is too hot or cold), flashing slowly
(battery pack is waiting for another pack to finish charging) or continuous (pack is charging).
• A fully discharged battery pack with an internal temperature in the normal range will charge
in about 30 to 185 minutes, depending on the battery pack.
• Heavily cycled batteries may take longer to charge completely.
• The Fuel Gauge lights on 18V battery packs 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 flash green during this maintenance charging.
• The second pack inserted in the charger will begin charging when the first pack inserted is
fully charged.
• If the light indicator flashes red and green, check that the battery pack is fully seated into the
bay. Remove the battery pack and reinsert. If the light continues to flash red and green,
remove pack(s) and unplug charger for at least 2 minutes. After 2 minutes, plug charger back
in and insert pack. If the problem persists, contact a MILWAUKEE service facility.
• If the light indicator does not come on, check that the battery pack is fully seated into the bay.
Remove the battery pack and reinsert. If the light indicator still does not come on, remove
pack(s) and unplug charger for at least 2 minutes. After 2 minutes, plug charger back in and
insert pack. If after these attempts the light indicator still does not come on, contact a
MILWAUKEE service facility.
