Possible Cause
Use of an
average-reading AC
voltmeter to read
output voltage.
Battery is almost fully
discharged.
No AC power at the
AC wall outlet.
AC charger is faulty.
Battery charge (%)
reading on digital
display is only
accurate when the
Duracell® Powerpack
has been disconnected
from all appliances
and all charging
sources for 15
minutes.
Solution
The modified sine wave (MSW)
output of the Duracell® Powerpack
requires a true RMS reading meter,
such as the Fluke 87 series, for
accurate measurement.
Press display function button to
verify battery status and recharge the
Duracell® Powerpack as necessary.
"Battery Charge %" reading on the
digital display is only accurate when
the Duracell® Powerpack has been
disconnected from all appliances and
all charging sources for 15 minutes.
Ensure power is available at the AC
wall outlet.
Replace the AC charger.
Unplug the charging sources and any
appliances and let the Duracell®
Powerpack rest for 15 minutes to
obtain an accurate reading.
