- Delta-peak (Delta-peak voltage sensitivity):
Set the Delta-peak voltage sensitivity at
termination. (Disable, Delicate, Default, 5-20mV/cell)
Disable:
The charger would not detect Delta-peak voltage for termination. To terminate
charging process, the charger will check the parameters set up at other safety parameters
like max. capacity, safety timer or safety temperature. If anyone has been reached at its
limit, the charging process will be terminated.(for NiMH only)
Delicate: The charger will detect a very small variation at delta-peak voltage. Some NiMH
batteries which shows small voltage-drop at peak need to be use this option.
Default: If you do not know much about this function, or for ordinary batteries, select this
mode. 15mV/cell for NiCd or 10mV/cell for NiMH will be used.
- End current: Set the final charging current at termination. The end current should be less
than the initial charge current. (Auto, 60-500mA)
Auto: The process will be terminated when the charging current go to 1/10 of its initial
value. Otherwise ,the charge current will be decreased until the designated value has been
reached.
- Trickle curr:
Activate or deactivate the trickle charge after the termination of
process.(Off, 50-300mA)
- Peak delay:
This restrains the delta-peak voltage detection until the time has reached.
This prevents a premature cut-off from the battery of high internal resistance. The default
value is one minute.(1-15 minutes)
- No. cycles:
The number of cycles in the process. (1-10 times)
- Waste time:
To avoid the battery from rising temperature caused by the internal chemical
reactions. There should be a brief cool-off time between cycles.(0-60 minutes)
The most distinctive point on the voltage
curve of a charging battery in response to
a constant current is the voltage peak
that occurs as the cell approaches full
charge. The voltage will slightly drops
after its maximum point. The charger
works with proven 'Delta-peak voltage
termination' to terminate charge process
for NiCd and NiMH batteries. The actual
termination point depends on the
charging characteristics of the particular
battery. Please refer the specification
which is provided by the battery
manufacturer.
