oDo not expose the cable to hot surfaces or sharp edges.
oNever use a charger which has a damaged cable.
oAvoid metallic tools falling on top of the battery. The battery could cause sparking, create
a short-circuit, or an explosion in another electrical component.
oWhen working with the battery remove personal metallic items such as rings, armbands,
necklaces, watches and so on.
oNever smoke in proximity to the battery or motor. Avoid sparks or flames.
oTo reduce the risk of electric shock, remove the power plug of the charger from the mains
before each maintenance or cleaning operation. Switch off the controls to reduce the risk.
oThe charger should not be used by children or by people who are not able to understand
the manual.
2Main features

6Ah to 160Ah. The charger however is able to preserve the charge of batteries up to
200Ah.
oCharger with new switch mode, high efficiency and low weight.
oExtra-low power consumption for standby mode.
oSimple to operate, clear state of charge display.
oFully microprocessor-controlled.
oDiagnostic of the initial battery condition.
oA low starting battery voltage can be caused by deep discharge or severe sulphating.
oBattery voltage analysis, where possible automatic repair (desulphating).

1. Desulphating
2. Soft Start charging
3. Bulk charge (maximum current)
4. Absorption charging
5. Reconditioning
6. Float + Pulse
7. Charge retention charging
oProtection against short-circuiting due to incorrect polarity:
oHeavy duty cable
oCorrosion-resistant output plug connector
oThe charger can be attached to the wall using four screws.
3Protection functions
The charger contains 4 protection devices:
oINTERNAL OVERHEATING PROTECTION:
The charger is equipped with an electronic circuit which provides protection against
overheating and over-charging. If the charger overheats, it reduces the charging current.
Once the temperature has dropped, the charger works normally again
oTIMER PROTECTION:
The charger provides the maximum charge time control for every charging level. The charger
switches off when it attempts to charge batteries with excessive capacity or batteries which
are defective. To protect the battery it is no longer charged, and the RED LED flashes slowly.
If this situation occurs, please check the battery using a battery tester.
oINCORRECT POLARITY PROTECTION:
The charger has protection against incorrect polarities. If the poles are transposed, the red
LED lights up. Change over the connections to the correct sequence. To do this you do not
need to remove the charger from the power supply.
oSHORT-CIRCUIT PROTECTION:
The charger has an initial short-circuit protection. If the charger detects a short circuit in
the output cables, the red LED lights up. Disconnect the charger from the mains and create
the correct connection. As soon as the charger detects an initial short-circuit or transposed
poles, the charging program ends, to avoid danger.

8ECO mode
oIf AC power is connected and the battery is not connected, the charger automatically
changes to ECO mode.
oIf AC power is displayed and the battery is disconnected, the input power is less than
1.5W, equating to a daily power consumption of 0.04 kWh.
oOnce the battery is fully charged, and during the charge retention phase, the complete
power consumption is around 0.05 kWh per day.
9Charging instructions
STEP 1 - Check before charging & electrolyte level check
oCheck the battery electrolyte level and if req. top up with distilled water. (This only applies
for maintenance-free wet batteries.)
oCheck on the battery label whether it is a 12V battery. Otherwise this charger is not
suitable.
STEP 2 - Connecting the battery charger to your battery
oIf the battery is outside the vehicle:
1. Connect the red cable from charger to the positive terminal (+) of the battery.
2. Connect the black cable from the charger to the negative terminal (-) of the battery.
oIf the battery is located in the vehicle, check whether the vehicle is positively or
negatively earthed.
If negatively earthed (most frequent):
1. First connect the red (+) cable to the positive battery terminal (+).
2. Then connect the black cable (-) to the negative battery terminal (-) or to earth on
the bodywork.
(Note: Keep away from the fuel line!)
If positively earthed:
1. First connect the black (-) cable to the negative battery terminal (-).
2. Then connect the red cable (+) to the positive battery terminal (+) or to earth on the
bodywork.
(Note: Keep away from the fuel line)
STEP 3 - Connect the battery charger to the power supply (220-240V)
oConnect the battery charger to the mains power socket.
oThe charger starts automatically.
(Note: If the LED of the fault display lights up red, please check your connections, since it is
likely that the positive and negative contacts are transposed. Further information can be found
on the fault-finding page).

CHARGING PROCESS:
oCheck of the battery starting condition (battery analysis)
Once the battery is connected and the AC power is switched on, the charger automatically
analyses the condition of the battery and checks whether Soft Start, desulphating, or Bulk
Charging should be activated.
oIntelligent charging mode
The charger automatically carries out the following steps:
1. Desulphating
oThe 20% charge LED lights up.
othe device detects sulphated batteries and dissolves the sulphate crystals through
pulsing voltage and current.
othe device ensures that the electrolyte liquid enters a well-distributed condition.
oThis allows the battery capacity to be restored if req.
oThe battery voltage slowly increases.
2. Soft Start
oThe 20% charge LED is on.
oThe battery voltage slowly increases.
3. Bulk charge (maximum current)
oThe 80% charge LED is on.
oThe battery can be charged up to approx. 80%.
oThe charger provides an almost constant current, until the battery voltage reaches
the set value.
4. Absorption mode
oThe 80% charge LED is on.
oThe battery can be charged up to approx. 95%.
oThe charging current drops and the charge voltage remains constant at the set
value.
Battery analysis
oCharging is interrupted briefly while the battery voltage is measured.
oIf the battery voltage drops too quickly, the battery is likely to be faulty.
oThe full LED flashes .
5. Reconditioning
oThe charger increases the voltage, in order to create an acid mix through controlled
gas formation, which will charge the battery evenly to full level.
oThe full LED flashes .
6. Float mode
oThe full LED lights up.
oThe battery is charged at a constant voltage until it is full.
oAs soon as the voltage drops, the device provides another charging pulse.

9
7. Charge retention charging
oThe full LED lights up.
oThe programme activates a special charging waveform and monitors the battery
voltage fluctuation.
oIf the battery voltage drops, the special pulses keep the battery in optimal
condition.
oIf the battery voltage drops further still, the battery charger switches over to bulk
charging.
In charge retention mode the battery can remain connected to the battery during the off-
season period. If possible, check the electrolyte liquid level in the battery.
STEP 4 - disconnecting the charger from the battery
oIf the battery is outside the vehicle:
1. Disconnect the mains plug.
2. First remove the black (-) cable and then the red (+) cable.
3. Only with batteries which are not maintenance-free: Check the electrolyte level and if
req. top up with distilled water.
oIf the battery is inside the vehicle:
1. Disconnect the mains plug.
2. Remove terminals (see 2a or 2b).
2a. If negatively earthed (most frequent):
1. Remove the black (-) cable from the bodywork earth or the negative battery
terminal (-).
2. Remove the red (+) cable from the positive battery terminal (+).
2b. If positively earthed:
1. Remove the red (+) cable from the bodywork earth or the positive battery
terminal (+).
2. Remove the black (-) cable from the negative battery terminal (-).
3. Only with batteries which are not maintenance-free: Check the electrolyte level and if
req. top up with distilled water.
