Radient Duplex Duplex RDNA0397 Owner's manual - page 3
Never attempt to charge or discharge the following types of battery:
A battery pack which consists of different types of cells (including cells from different
manufacturers).
A battery that is already fully charged or only slightly discharged.
Non-rechargeable batteries (explosion hazard).
Batteries that require a different charge technique from NiCd, NiMH, LiPo or Gel cell
(Pb, Lead acid).
A faulty or damaged battery.
A battery fitted with an integral charge circuit or a protection circuit.
Batteries installed in a device or which are electrically linked to other components.
Batteries that are not suitable for charging at the rates that the charger delivers during
the charge process.
LiFe
Voltage level:
3.3V/cell
Maximum charge voltage:
3.6V/cell
Allowable fast charge current:
4C or less
Discharge voltage cut off level:
2.0V/cell or higher
Pb (Lead-acid)
Voltage level:
2.0V/cell
Maximum charge voltage:
2.46V/cell
Allowable fast charge current:
0.4C or less
Discharge voltage cut off level:
1.75V/cell or higher
To avoid a short circuit between the charge leads, always connect the charge
leads to the charger first, then connect the battery. Reverse the sequence
when disconnecting. If using a charging squid, ensure that none of the
connector contacts can touch (together or a conductive surface) and short out
which could cause damage to the charger and/or battery.
NiCd and NiMH battery charge/discharge and discharge/charge cycles
Pb (Lead Acid) battery program
You can set the charge and discharge sequence on the
left and the number of cycles on the right. You can
balance, refresh and break-in a battery using this
function. You can also set a temporary cool-off (or ‘waste
time’) procedure.
Press the ‘Battery/Stop’ button to stop the program. You
can press the ‘Start/Enter’ button to alter the charge
current. A sound is emitted to indicate the end of program.
This program is only suitable for charging Pb (lead-acid) batteries with nominal
voltages from 2 to 20V. A Pb (lead-acid) battery is completely different from a NiCd /
NiMH battery. These batteries can only deliver a much lower current lower in
comparison to their capacity. The same restriction applies to the charging process.
Therefore the optimum charge current should only be 1/10 of the capacity. Do not
attempt to fast charge a Pb battery. Please follow the instructions provided by the
battery manufacturer. Press the ‘Start / Enter’ button to make the charge current blink
and then alter the value using the ‘Increase’ or ‘Decrease’ buttons. Press the
‘Start/Enter’ button to store the value.
When the end of the cycle approaches, you can see the
capacity of the battery being charged or discharged. You
can also press the ‘Increase’ or ‘Decrease’ button to
display the result of each cycle.
Set the desired charge current on the left and nominal
voltage on the right. The current range 0.1-8.0A. The
voltage should match the voltage of the battery being
charged. Press the ‘Start/Enter’ button for more than 3
seconds to start charging.
The screen displays the real-time charging status. Press
the ‘Start/Enter’ key to alter the charge current. Press the
‘Start/Enter’ button again to store the value. Press the
‘Battery/Stop’ key to end the program.
