Fuel Gauge Battery Packs
Some DeWALT battery packs include a fuel gauge which consists
of three green LED lights that indicate the level of charge
remaining in the batterypack.
To actuate the fuel gauge, press and hold the fuel gauge
button

illuminate designating the level of charge left. When the level of
charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to berecharged.
NOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end-userapplication.
