Charging Battery
The Joule 3.0 is powered by a user replaceable lithium-ion battery that can be recharged using
the included USB cable and a computer. A 5VDC 400mA charger can also be used (not included).
A fully charged battery can run for approximately 60 hours before it must be recharged. Recharg-
ing completely, via USB cable or AC adapter will take approximately six hours. The battery level is
indicated in the title bar. The Joule 3.0 is fully charged at the factory, but shipping and handling
may inadvertently consume charge. For more information see Important Precautions section on
page 38.
