Battery Charger INTELLI 3
13
After this time, the INTELLI 3 automatically switches to sleep mode.
If the battery voltage falls below 12.7V, the INTELLI 3 automatically awakens and
restarts the charging process with the battery test.
2. Pure lead (AGM round cells)
After connecting the battery, a battery test is performed. During the test phase, the
INTELLI 3 detects whether the battery is exhausted or sulphated and switches to the
appropriate charging program.
If the battery begins to charge, I-charging will proceed fi rst. The charging current is
gradually increased in order to recognise the capacity of the battery that is connec-
ted. The maximum charging current will be automatically adjusted to the capacity of
the battery.
If the fi nal charging voltage of 14.7V has not been reached within 24 hours, the
INTELLI 3 will assume that there is a short circuit in the cells. The charging is can-
celled and the notifi cation „battery defect - shorted cells“ appears in the display.
If the fi nal charging voltage of 14.7V has been achieved, the charging process will
continue with the U1-charging. During the U1-charging, the voltage will be main-
tained at 14.7V. The charging current thereby also decreases over the charging time.
If the charging current falls below 0.2A, or if the charge is longer than 5 hours, the
U1-charging will be terminated. The INTELLI 3 skips to trickle charge
(maintenance mode).
In maintenance mode (U2-charging) the charging voltage will be down-regulated
to 13.7V.
This charging program does not involve switching into sleep mode! Every hour,
equalisation charging will be done for 10 minutes.
During equalisation charging, the charging voltage will be increased to 16.0V. A
current limitation to 0.2A prevent overcharging of the battery. This equalisation
counteracts a differing charging status of the individual cells (cell drift). This ensures
that each individual cell is completely charged. The INTELLI 3 then switches back to
maintenance mode with 13.7V.
3. LiFePo
After connecting the battery, a battery test is performed. During the test phase, the
INTELLI 3 detects whether the battery is exhausted and switches to the appropriate
charging program.
If the battery begins to charge, I-charging will proceed fi rst. The charging current is
gradually increased in order to recognise the capacity of the battery that is
connected. The maximum charging current will be automatically adjusted to the
capacity of the battery.
If the fi nal charging voltage of 14.7V has not been reached within 24 hours, the
INTELLI 3 will assume that there is a short circuit in the cells. The charging is
cancelled and the notifi cation „battery defect - shorted cells“ appears in the display.
