Charging process of the automatic
charger
I phase (fig. 5 A, page 4)
The empty battery is charged with constant current of 8 A at the beginning of
the charging process. The green "Charging" LED goes on.
U0 phase (fig. 5 B, page 4)
The phase of constant charging voltage with decreasing charging current
begins once the charging voltage is at approximately 14.4 V.
U phase, (fig. 5 C, page 4)
The IU0U automatic charger switches to the lower retention voltage of 13.6 V
if the charging current falls below 1 A or the maximum charging time
(15 hours) is exceeded. The battery is fully charged, the green LED goes out.
Note:
I
To avoid battery overcharging, retention voltage is switched to
15 hours after switching on the IU0U automatic charger,
irrespective of the charging current.
