Charging with the AC Charger
Using the AC Charger is the simplest method for recharging
the battery. While charging from an AC source, the Charging
Status LED on the Control Panel will flash. The LED will
illuminate steady when the battery has reached capacity.
Charging using this method can take approximately 35 hours
assuming the battery is fully-discharged and that there is a
full 120 volts of power at the AC wall outlet being used. If
the voltage at the wall outlet is less than 120 Vac, it may take
more than 35 hours to fully recharge the XPower Powerpack.
If, after 35 hours of charging, the green Charging Status LED
is still flashing, continue to charge the unit for another
15 hours.
The AC Charger for the XPower Powerpack uses standard
120 Vac power outlets. The AC Charger Input Socket is
located in the Storage Compartment on the back of the unit.
The Input Socket connects to a regulated relay that monitors
the input for charging to prevent the battery from being
overcharged. Once the battery reaches 100% charge level, the
relay opens to disconnect the charging source from the unit
and the unit goes into a maintenance charge mode. This
feature allows the XPower Powerpack to remain connected to
the AC Charging source until it’s needed to power loads.
It is recommended that the XPower Powerpack be stored with
the AC Charger connected to a 120 Vac power outlet if
possible. This keeps the battery fully charged and ready for
use. This storage method also prevents the battery from being
over-discharged by non-use over a long period of time. If you
must store the XPower Powerpack with no AC power
available, remember to pull it out and recharge it
approximately every three months. Failure to do so may
irreparably damage the battery and renders the unit
inoperable. Damage occurring in this manner is not
covered by the product warranty.
Note : You may hear a clicking noise when the relay opens up to
start charging. This is normal. It should stop as the charging
voltage rises. If the clicking noise does not stop, disconnect the
AC Charger and contact Customer Service for assistance.
