4. CONNECTING THE BATTERY
Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. The
positive battery terminal is typically marked by these letters or symbols (POS,P,+). The negative battery terminal is typically marked by these
letters or symbols (NEG,N,-). Do not make any connections to the carburettor, fuel lines, or thin sheet metal parts. The below instructions are for a
negative ground systems (most common). If you vehicle is a positive ground system (very uncommon), follow the below instructions in order.
1. Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS,P,+) battery terminal.
2. Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG,N,-) battery terminal or vehicle chassis.
3. Connect the battery chargers' AC power plug into the mains power supply. Do not face the battery direction when making this connection.
4. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first.
Note: LED will indicate a solid Red if the battery clamp or eyelet terminal connector are connected to the wrong terminal,
reverse the battery connectors.
5. CHARGING THE BATTERY
1. Verify the voltage and chemistry of the battery.
2. Confirm that you have connected the battery clamps or eyelet terminal connectors properly and the AC plug is plugged into the mains supply.
3. The charger will begin in Standby mode, indicated by an orange LED. In Standby, the charger is not providing any power.
4. Press the mode button to toggle to the appropriate charge mode (press and hold for three seconds to enter an advanced charge mode) to
select the voltage and chemistry of your battery.
5. The mode LED will illuminate the selected charge mode and the Charge LEDs will illuminate (depending on the health of the battery)
indicating the charging process has started.
2. CHARGING MODES (CONTINUED)
The JEFBATCHG3.5-612 Dynamo 3.5A Battery Charger
has six modes: Standby, 12V/3.5A NORM, 12V/3.5A
COLD/AGM, 12V/1A NORM, 12V/1A COLD/AGM,
12V REPAIR and 6V, 3.5A NORM.
These "Press and Hold" modes are advanced charging
modes that require your full attention before selecting.
"Press and Hold" are indicated on the charger by "MODE".
It is important to understand the differences and purposes
of each charge mode. Do not operate the charger until
you confirm the appropriate charge mode for your battery.
See the various charge modes on page 1 of this manual.

3. Battery is connected incorrectly
7. CHARGING PROCESS
Step Explanation
1&2. Analyse and Diagnose Check the initial condition of battery, especially voltage.
3. Reverse Connection Detection Detect battery if connects right.
4. Heavy Current Charge at heavy current to approximately 80% of battery capacity.
5. Gentle Current Charge with gentle current until the maximum capacity of battery.
6. Stop Detect the full battery capacity, stop charge. When the voltage of battery falls down to a
certain value, charge cycle starts again.
