Charging the Lithium-Polymer Battery
With the Lithium-Polymer batteries installed in the battery compartment, plug the AC
end of the supplied 5VDC Charger/Power Supply into a standard AC wall outlet. Open
the rubberized access cover on the side of the BeltStation and plug the USB end of the
Charger/Power Supply into the USB connector. The Lithium-Polymer batteries will take
approximately 2¾ hours to charge from completely empty to completely full. This time is
the same with the BeltStation turned ON or OFF. A new, fully charged battery should power
a Tempest BeltStation for approximately nine hours.
Fast charging with the supplied fast charger requires a temperature range of 32° – 113° F.
Batteries can receive more than 500 charge cycles, and continue to maintain more than
70% of their power rating. The Tempest battery indicator will maintain its accuracy as
battery life decreases.
Alternatively, remove the Lithium-Polymer rechargeable battery from the BeltStation
and insert it into the optional 5-Bay Battery Charger. The Lithium-Polymer batteries
will take approximately 2½ hours to charge from completely empty to completely full.
See the battery charger manual for additional details.

BeltStation, but will not charge the AA batteries either.
» Supplied battery charger / power supply.
