Table 1:
Main Battery I: How to set the correct charging program for the
battery type (lead technology):
Move the
2 slide switches
behind the front panel of the unit to the desired position for
battery I (main battery)
using a small screw-driver. (Factory-adjusted position „Lead Acid“=Lead Acid Battery).

If not being specified divergently by the battery manufacturer, the suitable charging program
for the battery type (design, technology) can be determined by means of the following
description and the technical data (voltage rates U1 and U2, nominal temperature and dwell
times U1).
Note: The possible parallel/floating operation with consumers being connected to the battery
is also automatically considered by all charging programs.
„Lead Acid“:
Universal charging program for Lead,
Acid/Lead-acid
batteries
:
For charging and conservation of charge of
supply (board) batteries.
Ensures short charging times,
high charging factor and acid mixing for open standard batteries and closed, low-maintenance,
maintenance-free "non-solid electrolyte", "lead-acid", drive, lighting, solar and heavy duty batteries.
Also suitable for recently developed low-antimonous batteries and batteries with lead-silver alloy with
low and very low water consumption, as well as
AGM
batteries with charging voltage indication
"
14.4 V"
.
Universal Characteristic Line IU1oU2oU3:
U1 Main/Full Charging:
14.30 V - (28.6 V)
25 °C
2.5-6 h
U2 Full/Compensation Charging:
13.85 V - (27.7 V)
25 °C
2 h
U3 Full/Conservation/Storage Charging:
13.40 V - (26.8 V)
25 °C
Continuous
„AGM“:
Charging Program for Lead,
AGM / Fleece
Batteries:
Adapted to closed, gas-tight AGM (absorbet glass mat) batteries and batteries in lead-fleece
technology requiring a particularly high level U1 for full charging.
ATTENTION: It is highly recommended to check the specification sheet of the battery concerning
the high charging voltage U1
14.7 V
.
Unsuitable batteries might age prematurely due to loss of electrolyte!
Some manufacturers of
AGM
/ fleece batteries are also prescribing a "gel" or "acid" charging program
with
14.4 V
for charging!
In this case, please adjust "Lead Acid" (14.3 V/13.4 V)
Characteristic Line AGM- / Fleece IU1oU2:
U1 Main/Full Charging:
14.70 V !! (29.4 V) !!
20 °C
3-6 h
U2 Full/Conservation/Storage Charging:
13.50 V (27.0 V)
20 °C
Continuous
„Gel“:
Charging Program for
Lead Gel/Dryfit
Batteries
:
Adapted to closed, gas-tight
Gel
batteries with determined electrolytes, which are generally requiring
a higher charging voltage level and longer dwell times U1 to achieve short charging times with
particularly high capacity storage and to avoid total discharge, e. g. EXIDE, Sonnenschein dryfit-
Start, Dryfit-Sport-Line, DETA Gel Battery Funline, Bosch AS Gel Batteries Va/Z, AS Gel Drive
Batteries, AS Gel Lighting Batteries.
If not being specified divergently by the battery manufacturer, also recommended for batteries in
round cell technology, such as EXIDE MAXXIMA (DC) .
EXIDE, DETA, VARTA Characteristic Line Gel IU1oU2:
U1 Main/Full Charging:
14.40 V (28.8 V)
20 °C
8-12 h
U2 Full/Conservation/Storage Charging:
13.80 V (27.6 V)
20 °C Continuous
Not used (operates like the gel / dryfit program)
