charging characteristic
charging current
maximum charging voltage * 14.4V
float voltage
new charging cycle,
change-over to boost-charge * when battery voltage is about < 13.8V
IW boost-charge at max 10A arithmetic
mean, electronically limited, up to
maximum charging voltage
Uo then equalize-charge at constant 14.4V
selectable: 20 minutes duration for lead-
acid, 6h duration for lead-gel batteries
U
then automatic change-over to float-
charge at 13.8V
If due to high loads the float voltage of 13.8V cannot be provided, the battery charger switches over
from float to boost-charge.
