Safe Timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by current, then divide the
result by 11.9, set this number of minutes as the value for safety timer setting. If the
charger stopped at this time threshold, about 140% of the capacity will have been fed into
the battery.
For example:
Capacity Current
2000mAh 2.0A
3300mAh 3.0A
1000mAh 1.2A
This shows the trigger voltage for automatic charge termination of
NiMH and NiCd battery. The effective value ranges from 5 to 20mV
per cell. If the trigger voltage is set higher, there is a danger of
overcharging the battery; if it is set lower, there is a possibility of
premature termination. Please refer the technical specification of the
battery. (NiCd default: 12mV, NiMH default: 7mV)
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 becomes warm after cycles of charge/discharge
process. The program will insert a time delay after each charge/
discharge process to allow the battery enough time to cool down
before beginning next cycle of charge/discharge process. The valid
value ranges from 0 to 60 minutes.
When the charge process starts, the integrated safety timer starts to
run simultaneously. If an error is detected or the termination circuit
cannot detect whether the battery is fully charged or not, the unit is
programmed to prevent overcharging. Please refer to the below
statement to calculate the safe timer to be set.
Safety Time
(2000/2.0=1000)/11.9=84 minutes
(3300/3.0=1100)/11.9=92 minutes
(1000/1.2=833)/11.9=70 minutes
