3. Charging the battery

Motor vehicle manufacturers recommend
disconnecting the battery from the vehicle's electric
system prior to charging.
We wish to point out that even standard vehicle
models are equipped with numerous electric
modules (e.g. ABS, ASC, fuel injection pump, on-
board computer and car phone). Voltage peaks may
cause damage to electronic components. It is
advisable therefore to disconnect the battery from
the vehicle's electric system during charging.
Please note the instructions in the manuals supplied
with your car, radio, car phone, etc.
This charger is an automatic charger, i.e. it is particularly
suitable for maintenance-free batteries and for the long-
term and trickle charging of batteries not in constant use,
e.g. for boats, lawn mowers and the like. Battery gassing
is prevented by limiting the charging voltage to 14.1V
(2.35V per cell). Charging does not have to be
supervised.
To charge the battery, proceed as follows:
Figure 1: Undo or remove the battery plugs.
Figure 2: Check the level of acid in your battery. Top
up with distilled water if necessary.
Caution! Battery acid is corrosive. Wash off acid
splashes immediately and thoroughly with plenty of
water and consult a doctor if necessary.
Danger! Hazardous electrolytic gas may arise during
charging. It is imperative, therefore, to avoid sparking
and open flames during charging. Risk of explosion!
Figure 3: First connect the red charging lead to the
positive pole of the battery.
Figure 4: Then connect the black charging lead to the
negative pole of the battery.
Figure 5: Once the battery is connected to the
charger you can connect the charger to a
230V ( 50Hz socket-outlet. It is prohibited to
connect the charger to a socket-outlet with
any other supply voltage.
Figure 6: Calculating the charging time:
The charging time depends on the battery's
charged condition. For an empty battery it is
possible to calculate the approximate
charging time with the following equation:
capacity in Ah
Charging time/h =
amps (charging current arithm.)
Example: 24 Ah = 9.6 h max.
2.5 A
A normally discharged battery is
characterized by a high initial charging
current that is approximately equal to the
rated current and which decreases as the
charging progresses.

An old battery which does not show any
decrease of charging current has a defect,
e.g. short-circuiting of battery cells or
ageing.
Figure 7: The only way to determine the exact
condition of the battery (level of charge) is
to measure the acid density with an
acidimeter.
Please note: Gases are released during the charging
operation (bubbling on the surface of the battery liquid).
Make sure the room is well ventilated.
Acid density values (kg/l at 20°C)
1.28 battery charged
1.21 battery half charged
1.16 battery empty
Figure 8: Pull the power plug out of the socket-outlet.
Figure 9: First disconnect the black charging lead
from the negative pole of the battery.
Figure 10: Then disconnect the red charging lead from
the positive pole of the battery.
Figure 11: Screw or press the battery plugs back in
place.

4. Overload protection

Figure 12: The flat fuse (10A) provides protection from
polarity reversal and short-circuiting. A
defective fuse has to be replaced by one of
identical amperage. Before you replace the
fuse, remove the power plug from the
socket-outlet and disconnect the charging
terminals from the battery.
An automatic circuit-breaker interrupts the
charging in the event of thermal
overloading. The circuit-breaker switches
on again automatically after a cooling
interval.
5. Servicing and cleaning the battery
and charger
Make sure that your battery is always fitted securely
in the vehicle.
Check that the battery is properly connected to the
vehicle's electric system.
Keep the battery clean and dry. Apply a little acid-
free and acid-resistant grease (Vaseline) to the
terminals.
The level of acid in non-maintenance-free batteries
should be checked about every 4 weeks. Top up
with distilled water as necessary.
Keep the charger in a dry room. Remove any signs
of corrosion from the charging terminals.
