Charger Operation; Start Charging - Albrecht DG-630 N Manual De Usuario

the manufacturer the batteries must be certified for boost-charging
(this applies to most of the newer battery types).
Never do this: Never place a radio without batteries in the stand-alone
charger. The stand-alone charger is only intended to charge batteries
and cannot operate the radio. Without batteries the higher charging
voltage can damage the radio.

Charger operation:

The stand-alone charger comes with intelligent charging circuit with a
processor, which was especially developed for boost charging and
detects the charge status of the battery to switch off at the right time.
This is the point when the internal pressure of the battery increases and
the voltage is at its peak (the so-called Delta-U detection).
The charging duration depends on the battery capacity. Standard
batteries with 1000mAh are already fully charged after less than 3 hours,
batteries with higher capacity achieve 90% after the respective duration.
At this point the charger switches to the so-called trickle charge.
Now only approx. 5% of the maximum charging current is drawn.
Batteries can tolerate this current (approx. 20mA) indefinitely, without
being overcharged. This trickle charge also adds the missing last 10%
capacity within 1-4 hours after the boost charge.
Connect charger:
Connect the mains adaptor to a 230V wall outlet and connect the cable
to the power jack at the rear of the stand-alone charger. After correct
installation the left-hand red PWR LED lights up.
Only use the supplied original mains adaptor for 220/230VAC. Other
power adaptors may have different specifications and may cause
dangerous overcharge effects. Direct connection to vehicle onboard
power is not possible, since for charging 9 x NiMH batteries 12V is not
sufficient.
Tip for use in vehicles, trucks or boats: Use a commercially available
12V notebook adaptor, set to 20...22VDC and connect to the power jack
of the DG 630 N if it is unavoidable to charge batteries in vehicles! The
polarity of the DC plug of the notebook adaptor is of no consequence.

Start charging:

Insert the batteries in the battery compartment and observe the correct
capacity as marked inside the compartment. Ensure that the batteries
make good contact by attaching the battery pack to the radio and
switching it on.
