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.
