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 error detected or the termination circuit can not detect
whether the battery is fully charged or not, this unit is programmed to
prevent overcharging. Please refer to the below statement to calculate
the timer you set.
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 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
