Charging process
Supply battery (battery II)
The automatic charger has an electronic reverse battery pro-
tection. The charging current is only released if the battery is
correctly connected and there is a minimum voltage of 1.5 V.

While it is being charged, the battery voltage is monitored
constantly by way of the B+ measuring line. The charging
process is carried out in accordance with the charging refer-
ence line with a minimum of performance loss. (Charging
r eference line, see fig. 2).
Main charging phase
(all voltage values relate to a battery temperature of 20 °C)
Charging with maximum constant charging current until a bat-
tery voltage of approximately 14.4 V is reached. If in this range
of the main charging phase, the charging current falls below
90 % of the rated current due to internal battery resistance
and resistivity, the afterloading phase is started.
Afterloading phase
(all voltage values relate to a battery temperature of 20 °C)
The charging voltage is kept at a constant 14.4 V for a period
of 10 hours for gel / AGM batteries or four hours for liquid
electrolyte batteries. At the end of this period, it changes to
the trickle current phase. If during this period, the current
increases to over 90 % of the rated current and if at the same
time the battery voltage drops to below 13.2 V for a period of
more than 15 minutes for liquid electrolyte batteries and more
than two hours for gel batteries and AGM, it switches back to
the main charging phase.
Trickle charging phase
(all voltage values relate to a battery temperature of 20 °C)
The charging voltage is set to 13.8 V. The charging current
drops to the equalizing charge value necessary for the bat-
tery. If due to the consumer, the charging current increases
to its rated value and if the battery voltage drops for at least
2 minutes below 13.2 V, the device switches back to the main
charging phase.
Parallel mode
If consumer current is used during the aftercharging phase or
the trickle charging phase, this is immediately recharged.
