Calculating the charging time
The charging time depends on the charge status
of the battery. If the battery was discharged
but is chargeable (not exhaustively discharged,
“Lo” displayed, or defective), the approximate
charging time up to approx. 80% (fig. 1)
Charging can be calculated using
the following formula: (fig. 2).
Note:
The charging current should
be 1/10 to 1/6 of the battery
capacity.
Charging programs
STD:
Charging program for lead acid batteries (wet, Ca/Ca, EFB batteries) and gel
batteries. The “STD” LED (11) illuminates the first time the charger is used.
AGM:
Charging program for AGM batteries. Press the Battery select button (4) to switch
from the STD to the AGM charging program.
Winter:
Recommended charging program (higher end-of-charge voltage) in cold weather
(ambient temperature -20 °C - +5 °C) for normal lead acid batteries (wet / Ca/Ca
batteries) and AGM batteries. Press the Battery select button (4) to switch from the
AGM to the “Winter” charging program.
