38 Allegro CX Owner’s Manual
Note: It commonly takes 2.5 to 3 hours to fully charge a battery pack,
however in warmer temperatures, or when using accessories for the Allegro,
it can take up to 5+ hours.
Power Connector
A standard external DC power input connector is located on the top
of the Allegro. The connector is 5.5 x 2.1 mm, 12 to 20 V DC. The AC
power adapter and optional vehicle power adapter are inserted into
this connector.
Charging Accessories for NiMH Battery Packs
There are several charging options available for the Allegro. The
most common is the AC power adapter that is shipped with your
Allegro. The USB/Power Dock, vehicle power adapter, and external
battery charger are all optional ways of charging the Allegro and can
be purchased separately.
AC Power Adapter
Using the AC power adapter, the battery pack is recharged without
removing it from the Allegro. Please note you must use the adapter
included with the Allegro or one that is capable of supplying
adequate current (12 V at 1 Amp). Otherwise, the battery pack could
be damaged.
You can run the Allegro from the adapter while batteries are being
charged. To charge the battery, complete the following steps:
Plug the AC charging adapter into an AC outlet.
Insert the connector into the external power input jack located on
the top of the Allegro case.
When the batteries are fully charged, the charging circuit
switches into trickle charge mode. You can leave the Allegro
connected to the adapter continuously without overcharging or
damaging the batteries as long as the power is not interrupted.
Note: If power is interrupted frequently (for example when installed in
a vehicle), use vehicle mode to prevent battery damage from overcharging.
Refer to the Using Vehicle Power section of this manual.
