2.2 – Connecting to a Battery in a vehicle.
Before connecting, determine if the vehicle is Negative (-) or Positive (+) Earthed. Negative earthed vehicles are
most common and use the chassis as an Earth by connecting the Battery Negative Terminal to a conductive
chassis point. The purpose of connecting the charger through the chassis is to eliminate any power spikes
going through the vehicles sensitive electrical system.
If you are unsure, please seek advice from a qualified person before connecting.
2.2.1 Connecting Negative Earth Vehicles (Most Common)
Connect the RED Output Lead (Battery Clip) from the
charger to the Positive (+) Battery Terminal and ensure
a good connection is made.
Connect the BLACK Output Lead (Battery Clip)
from the charger to a clean conductor point on the vehicle's
chassis away from any fuel lines or moving parts.
2.2.2 Connecting Positive Earth Vehicles (Less Common)
Connect the BLACK Output lead (Battery Clip) from the
charger to the Negative (-) Battery Terminal and ensure
a good connection is made.
Connect the RED Output Lead (Battery Clip) from the
charger to a clean conductor point on the vehicle's chassis
away from any fuel lines or moving parts.
3. Connect to 220-240V AC mains power
Connect the battery charger to AC power via an approved AC mains socket and ensure the wall switch is off.
Once the AC plug is connected and secure then switch on the wall outlet. The charger will then sound a tone for
0.5 seconds and all of the LEDs on the touch panel will illuminate for a short time.
4. Charging & Charging Mode Selection
Once connected to power supply and the battery and turned on, the charger will automatically enter charging
status, it is working on slow charging stage by default. The orange LED in section 1 will illuminate, and the
charger will automatically detect the battery. As the MODE button is pressed, you can select the desired
charging mode, the charger switches immediately into the Nor/GEL, Fast and AGM/Deep cycle battery charging
mode
5. Disconnecting the Charger from the Battery.
Firstly, switch off the mains supply and disconnect the charger from the mains socket.
For Battery out of vehicle:
Remove the BLACK Output Lead (Battery Clip) from the Negative (-) Battery Terminal.
Remove the RED Output Lead (Battery Clip) from Positive (+) Battery Terminal.
For Battery in vehicle:
Remove the Output Lead (Battery Clip) from the chassis connection.
Remove the Output Lead (Battery Clip) from the Battery Terminal.
Finally, inspect the liquid levels in each cell and top up. If necessary, using the correct fluid. Replace the caps.
Any surplus fluid around the cell tops should be wiped off (this should be done with extreme care as it may be
acidic/corrosive). Where appropriate, if the battery has been removed for charging, replace it and reconnect the
cables.
