An optional feature using temperature probe contacting
the surface of battery, the temperature cut-off can be on
or off. If it is on, set the maximum temperature at which
the charger should allow battery to reach during charge,
Once a battery reaches this temperature during charge,
the process will be terminated to protect the battery.
The battery is on the cyclic process of charge and
discharge can often become warm after charge or
discharge period. The program can insert a time delay to
occur after each charge and discharge process to allow
the battery adequate time to cool down before being
subjected to the next process. The value ranges from 1
to 60 minutes.
When you start a charge process, the integral safety
timer automatically starts running at the same time.
This is programmed to prevent overcharge the battery
if it proves to be faulty, or if the termination circuit
cannot detect the battery full. The value for the safety
timer should be generous enough to allow a full
charge of the battery .
Safe timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by current, then divide the
result by 11.9, set this number as the value for safety timer setting. If the charger stopped at
this threshold, about 140% of the capacity will have been fed into the battery.
For example:
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
This program sets the maximum charge capacity that
will be supplied to the battery during charge. If the delta-
pack voltage is not detected nor the safety timer expired
by any reason, this feature will automatically stop the
process at the selected capacity value.
