Charging process

Supply battery charging process (battery II)
The charger has electronic protection against polarity inver-
sion. The charging current is only released once the battery
is correctly connected and a minimum voltage of 1.5 V is
applied. While it is being charged, the battery voltage is
monitored constantly by way of the B+ measuring line.

The charging process follows the charging characteristic
curve, with minimal energy loss (for the charging characteris-
tic curve, fig. 2).
Bulk phase
(all voltage values with respect to a battery temperature of 20 °C)
Charging with maximum constant charging current until the
battery reaches 14.4 V. If the charging current drops below
90 % of the rated current during this phase due to the internal
resistance of the battery and cable resistance, the absorption
phase is started.
Absorption phase
(all voltage values with respect to a battery temperature of 20 °C)
The charging voltage is held at a constant 14.4 V for ten
hours for gel or AGM batteries; for liquid electrolyte batteries,
this voltage is held for four hours. After this time, the device
switches to the charge phase. If during this period the current
rises to more than 90 % of the nominal current while the bat-
tery voltage falls to below 13.2 V for a period of 15 minutes
with liquid-electrolyte types or more than two hours with gel
or AGM batteries, the unit will automatically switch back to
the main charging phase.
Float phase
(all voltage values with respect to a battery temperature of 20 °C)
The charging voltage is set to 13.8 V. At the same time, the
charging current drops to the value necessary for the equalis-
ing charge of the battery. If the charging current rises to its
rated value due to a user and the battery voltage remains be-
low 13.2 V for at least two minutes, then the device switches
back to the bulk phase.
Parallel operation
If during the absorption or float phase, current is consumed, it
is recharged immediately.
