ply and switch on. Initially the red LED will illuminate indicating that the unit
is “Fast” charging the battery. When the battery reaches about 90% charged,
the unit will switch to “Slow” charging and illuminate the green LED. If the
battery is already charged before the power is switched on, the unit will go
straight to its “Slow” charge mode and illuminate the green LED immediately.
The “Slow” charging mode can be used to maintain a “Top-up” charge on
the unit when it is not being used. Before use, when charging is complete, the
charging socket cover must be replaced and secured by tightening the grub
screw provided.
The time taken to charge the battery will depend upon the state of discharge
of the cell and its capacity. Generally speaking it should take less than 8 hours
to fully charge a standard 7.2 Ahr battery, but if fitted with higher capacity cells
the charging will take proportionally longer. It is recommended that when a
unit has remained unused for some time (weeks) that it is charged before being
used to ensure that a sufficient capacity is available.
The unit should never be left in a fully discharged state for any length of time
(more than a week) as this will significantly impact on the life of the battery
pack. It is not necessary to wait until the “Low Battery” warning appears on
the display to begin recharging the battery, it is recommended that the unit is
put on recharge immediately after any significant use to ensure the unit is ready
for when it is next required.
If the operating life of the battery begins to reduce significantly, or if the time
taken to charge the battery begins to increase, then it is recommended that
the battery pack be replaced, refer to your service support for details. Refer to
section IX for instructions on replacing the Battery pack. Use only the Crowcon
supplied parts, see spares list, when replacing the battery pack.
Note: The user must comply with local environmental regulations when dispos-
ing of Detective+ battery packs.
