How to check the state of charge
Out from the box, the internal battery of MVQUICKAL has a state of
charge of about 50% or higher.
To verify the state of charge:
-
When the external battery is installed:
Press the “Check” button to verify the state. The LED will stay
on for about 3 sec showing the state (see table above). The
LEDs will flash when the internal battery is being charged.
-
When the external battery is not installed:
The LEDs are automatically alighted continuously displaying
the state of charge. However, if 60 minutes elapse without an
installation of a new battery, MVQUICKAL enters in a low
power mode and automatically shuts off. Press the “Check”
button to wake up the device and verify the state (see later).
The prediction of the state of charge based on cell voltage may
appear inaccurate especially when the device is requesting a high
current load. Under similar circumstances, the internal voltage drop
may be large enough to switch off the first LED [H] and apparently
displays a state of charge below 66%. In similar cases the LED
gauge is programmed with a pessimistic capacity prediction, and the
state of charge seems to reduce faster, especially for the first and
even the second LED [H M]. In any case the flashing 3

represents a critical threshold after which the camera should be
switched off or alternatively, a fresh battery installed.
How to charge the internal battery
MVQUICKAL has an internal battery pack that can be charged in
two different ways:
-
By connecting the MVQUICKAL charger provided through the
Push-pull connector on the side.
The internal battery will be charged automatically. The charger
will charge at 3A in constant current mode with the charge time
being roughly 30 minutes.
-
Automatically upon installation of a new battery:
Whenever an empty battery is swapped with a fresh battery, the
newly installed battery will restore the lost energy of
MVQUICKAL by charging the its internal battery with a 120mA
current for a maximum time of 90 minutes. This will ensure that
a maximum of 180mAh will be replenished in the internal
battery.
