• With the „INC“ button, you access the next setting (or with the button „DEC“ the previous
setting or return to the main menu with the button „BATT TYPE/STOP“).
For NiMH, NiCd or Pb batteries, you can set the so-called trickle charge here.
Briefly push the „START/ENTER“ button. Now the charging current flashes; set it as
usual with the buttons „INC“ or „DEC“ (50....200 mA). When selecting „OFF“, the function
is deactivated. Save the setting with the „START/ENTER“ button, the voltage stops
blinking.
• With the „INC“ button, you access the next setting (or with the button „DEC“ the previous
setting or return to the main menu with the button „BATT TYPE/STOP“).
If charging starts, the internal timer starts as well. If the charger cannot detect whether
the battery is fully charged for whatever reason (e.g. with delta-U detection), the charge
process is terminated automatically after a set time if the safety timer is set to ON. This
protects the battery from overloading.

However, do not set a time which is too short, otherwise the battery cannot be fully
charged.
Calculate the time for the safety timer as follows:
Examples:
Battery capacity
Charge Current
Timer time
2000 mAh
2.0 A
2000 / 2.0 = 1000 / 11.9 = 84 minutes
3300 mAh
3.0 A
3300 / 3.0 = 1100 / 11.9 = 92 minutes
1000 mAh
1.2 A
1000 / 1.2 = 833 / 11.9 = 70 minutes
Factor 11.9 is used to ensure that 40% more time is available before the safety timer
kicks in.
