Backpacker Series/SilverBoom Battery Pack Charging
The battery pack used on the Backpacker Series and SilverBoom is a self-contained
unit, which includes 1 battery and an internal battery charger.
The battery pack charger is designed to charge the lift battery and those of a mobility
product, switching between the 12-volt lift battery and the 24-volt mobility product
batteries, depending on which battery is in need of a charge. (The lift battery receives
priority when charging.)
NOTE: The charger will normally charge the battery pack first, then switch to the
mobility product charging output.
NOTE: Charging switches automatically to the mobility product when it is plugged
into the charger. The mobility product will be charged for one hour before switch-
ing back to top off the lift battery.
During charging, if the vehicle engine is shut off, an automatic charge shut-off timer
(lasting three hours) will start. If the vehicle remains off, and the vehicle’s battery is
in good condition, the charger will continue to charge the lift and mobility product
batteries for three hours then enter sleep mode. If the charger detects that the vehicle
battery is getting too low, the charger will enter sleep mode before three hours. Charging
will restart when the vehicle engine is started. Disconnecting then reconnecting the
24-volt mobility product will also restart charging and will reset the three-hour timer.
If the auxiliary power outlet or cigarette
lighter outlet is switched on and off
with the ignition key, then charging will
only take place when the ignition key
is in a power-on position.
The charger is powered by plugging it
into one of the vehicle’s auxiliary
outlets or cigarette lighter outlet. See
figure 5. It is recommended that the
charger be connected to a continuously
powered auxiliary outlet or cigarette
lighter outlet.
