At the beginning stage of operation, the charger provides the largest current with 40.8V dc of output voltag e (for 36V batteries) to
charg e batt eries. The LED indicator will lighten in red. After a period of time (probably a coup le of hours, based on the capacity of
batte ries), the charging current will decrease gradually. After reaching of its maximum value, the charger will go into
"floating-charge" stage. The LED ind icator will turn to green. The relationship between charg ing current and charging voltage for each
opera tion stage are shown in t he cur ves below :
