Description
The two batteries supplied with the QED are 18650 (protected) Lithium
Ion Batteries, like the battery in the image below:
18650 lithium-ion batteries are
charged up to 4.2V and down to
between 2V and 3V depending
on the cell's specification for
cut-off voltage.
To be safe, never discharge
lower than 3.0V unless you
know your cell's specification.
The QED displays the battery range from ~5.98 - 9.99 Volts
The QED is designed to run on a battery voltage of 10 Volts maximum
and 6 Volts minimum.
To protect the batteries, the QED will automatically turn off when the
battery voltage is below 6 Volts.
Note: When the battery is nearly flat a decimal point appears on the screen. If
the operator shuts down when the decimal point appears then current
settings will be saved.
Note: If the detector shuts off due to low battery then current settings will NOT
be automatically saved.
Warning:
Battery life
Batteries will last about 3-
4 months if they are left in
the QED, after which time
the batteries may be fully
discharged and you will
need to throw them away.
If you are not going to use
your QED for even a few
months I advise that you
remove the fuse to
prevent slow discharge to
a point where they cannot
be recovered.
It is advised to charge the
QED batteries every few
months
