8. Battery Pack
FUEL GAUGE
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. When less than 10% of
charge is left, 1 light on the fuel gauge will flash slowly.
NOTE: If the Fuel Gauge doesn‘t appear to be working, place the battery pack on the charger and
charge as needed.
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 as you work. 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.
NOTE: 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 cur-
rent 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 tempe-
rature of the battery could become too high. If this happens, the fuel gauge lights will flash in an
alternating pattern and the tool will not run. Allow the battery to cool down.
