1. Product description
De c-Go 12V charger series is designed for full automatic charging of 12V Gel and AGM
batteries. The charger contains the latest, state of the art power converter and the charge
process is controlled by a microcontroller.
If the safety precautions in this manual are observed and the charger is operated according
to this manual, optimal and save charging of the battery is guaranteed.
The charger consists of:
1. A high quality plastic enclosure.
2. A battery cable with a 3 pole connector for connecting to the 12V system and/or a
battery. (Supplied with two cables)
3. A mains cable for connecting to the public grid.
4. Two colored LED’s (Light Emitting Diodes) indicating the operation mode.
The charger operates full automatically and needs no adjusting.

Symbols:
Read the safety advices carefully.
Read the user manual before using the battery charger.
For indoor use only
Do not use the battery charger in a wet environment or in the rain.
The battery charger and batteries are not to be discarded with normal
household waste. Dispose properly according to the local regulations.
The battery charger is a class II appliance (double insulated)
The battery charger complies with the European CE requirements.
2. Safety advices
-This appliance can be used by children aged from 8 years and above and persons with
reduced physical, sensory or mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning use of the appliance in a safe
way and understand the hazards involved. Children shall not play with the appliance.
Cleaning and user maintenance shall not be made by children without supervision.
-Never use the charger in a wet environment (for example outside), spill fluids over the
enclosure or submerge in water.
-Do not use the charger if the cables are damaged, the enclosure is open, or the charger is
damaged in such way that internal parts become accessible.
-If the supply cord is damaged, it must be replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a hazard. If the charger is defective, do not
try to repair it.
-Make sure the charger is positioned stable.
-Keep a free zone of 10cm around the charger to ensure that heat, generated during
operation, can be removed.
-The battery charger is suited for the in Europe standard 220-240V/50Hz mains grid.
Operating the charger in places where different mains voltages are applicable will
damage the charger or render it unsafe. Please consult Your supplier in case of doubt.
-Charge specified batteries only. Do not recharge non-rechargeable batteries.
-Charge the batteries only if there is proper ventilation. Especially around the batteries.
While charging, a small amount of explosive gasses can be generated in the batteries.
inadequate ventilation in combination with open fire or sparks can lead to dangerous
situations.
-Do not disconnect the battery while it is charging. To reduce risk of sparking.
First disconnect the charger from the mains. Or wait until the charger has completed the
charge cycle.

-Batteries are capable of providing much energy in a very short time. Prevent short
circuits any way. For example walking over the cables or damaging the cables or
connector by improper use.
-Do not shorten the length of the charge cable.
3. Quick start guide
The battery charger is very simple to operate.
1. Connect the battery charger to the mains. The orange LED , marked will blink.
2. Connect the battery cable to the battery to be charged. When the battery charger
decides that the battery should be charged , The orange LED marked turns on
continuously and the charging will start.
3. As long as the orange LED marked is on and it is not necessary to use the battery, it
is recommended not to interrupt the charge process. Interrupted charges will shorten
the battery life.
4. When the battery is full the green LED, marked turns on. The battery can be used
now. However, if the battery will not be used directly, it is recommended to leave the
charger connected. The battery charger will keep the battery in optimal charged
condition.
5. If there is a problem, the charger will indicate this by quickly blinking the orange and
green LEDs simultaneously. Please consult the chapter “Problem solving”.
4. Operation
The battery charger is not suited for outdoor use.
Use the battery charger in a dry, well ventilated place.
Keep at least an area of 10cm around the enclosure for proper battery charger cooling.
During charging, the enclosure can become hand warm. This is normal.
The 20A version is equipped with a build in fan, operating automatically when the internal
battery charger temperature increases. For all versions the output power will be reduced in
case of insufficient cooling or too high ambient temperatures. When charging, the time
required for the total charge process may increase. In power supply mode the maximum
output current will be limited. For this reason, do not subject the battery charger to direct
sunlight.
Connections:
The battery charger is equipped with a EU plug for connection to the 220-240V/50Hz mains
grid.

English

The output cable has 3 connections:
Connect (A) to the battery or 12V system with one of the two included connection cables.
Red is positive (+) and black is minus (-).
For fixed installations the connection cable with the Ring Tongues are recommended.
The crocodile clamp connection cable should not be used to charge a battery in a fixed
setup.
Connector (B) is not used.
Operation:
After the battery charger has been positioned or mounted correctly, connect the battery
charger to the mains grid. The orange LED , marked will start to blink slowly.
This is the stand-by position indicating that no battery is connected.
Connect the battery cable to the battery or the equipment in where the batteries are
mounted. After 3 seconds the battery charger has detected if the battery can be charged.
If yes, it will start the charging process. The orange LED marked turns on. Also some
clicking sounds can be heard from inside the battery charger. This is normal.
If the battery is charged fully very recently, it is possible that the charging will not start.
The orange LED will keep blinking slowly until the voltage has dropped enough to enable
charging.
Depending on the state of charge and the battery capacity the charging process will take
minimal 1 and maximal 24 hours.
End of charge:
If the battery charger detects the battery is full, the green LED, marked turns on.
The battery may be disconnected and used. However, if the battery will not be used directly,
it is recommended to leave the charger connected. The battery charger will keep the battery
in optimal charged condition by applying a maintenance charge periodically. Also here some
clicking sounds can be heard from inside the battery charger. This is normal.

User tips:
-Prevent deep discharging of the batteries. The battery life will be reduced significantly.
Charge a deep discharged battery as soon as possible.
-Let the battery charger finish the charge cycle completely.
-If the battery is not charged for a longer period, for example during winter, connect the
battery charger to the mains once every month to recharge the battery. Battery self-
discharge and the quiescent current of the connected users will drain the battery charge
slowly.
-Do not charge the batteries below 0°C. Move the battery to a warmer place and start
the charge.
-If the charger has been disconnected from the mains, disconnect the charger also from
the battery to prevent slow discharge of the battery by the charger.
-Keep the ventilation openings clean and free of accumulated dust. Blow away the dust
and clean the battery charger enclosure eventually with a cloth slightly moistened.

6. Problem solving
In case there is a problem or there is a suspicion the charger is not operating as expected,
first check which of the indication LEDs are on. If both the orange and the green LED are
blinking quickly ( ½ second on, ½ second off followed by a 1 second pause), they are
indicating an error.
The number of flashes, between the pauses are indicating the error code.
Next, consult the next tables to diagnose the problem.
Table 1: Fault diagnostics
