Using rechargeable batteries with high internal
resistance can lead to a sharp drop voltage across
the battery terminals, disruptions in the power
supply circuit and unstable work device at partial
discharge batteries.
To charge the batteries out of the device, it is
recommended to use a battery charger to ensure
continuous operation and gentle care of your
battery pack with the function «minus delta
voltage» (-ΔV), which controls the end of charge
voltage drop when the battery reaches its
maximum capacity.
Power supply and built-in battery
charger
For stationary use, the device can use an external
stabilized power supply voltage of 5 V, 500 - 1000
mA (supplied or optional).
The device has a built-in battery controller and, if
necessary, you can charge the batteries directly
into the device by connecting it to a power source.
Warning! Power supply from the unregulated
voltage over of 5 volts can lead to failure of the
device!
Features built-in charger:
Battery charge current is within 100mA to 180mA
and applied for 5 hours, and is designed for slow
charging the battery capacity 600 - 1000 mAh,
then the charge is automatically disabled. In this
mode, the battery charge provides durability.
If the user place the batteries into the battery
module of smaller battery’s capacity, in this case
need to choice the charging capacity in the
“Battery capacity” (point Settings -> Battery
capacity) for a specific capacity.
During battery charging on the top panel lights the
red indicator, marked the “CHARGE”.
If user place the old batteries with high internal
resistance, that capacitance significantly lost,
defective or place exhausted batteries, the device
will ignore to charge them.
Warning!
It is strictly forbidden to
charge alkaline (Alkaline battery 1,5V) and
salt batteries in the device!
Charge of alkaline or saline batteries can lead to
an explosion, electrolyte leakage from them and
broken of the device!
