Operation
WARNING: Only use the 'Fast Charge' mode under the Charge Start Selector (6) for a short amount
of time. Do not leave the battery unattended while in 'Fast Charge' charging mode.
WARNING: Never charge a battery where the water level is low. These will produce a higher level of
explosive/flammable gas and damage the battery.
IMPORTANT: This is a three-stage automatic charger. Under 'Normal' charge mode, the charger can
remain connected to the battery for long periods of time. Monitor the battery's charge progress, then
disconnect the charger after the battery has reached the desired percentage level.
IMPORTANT: Ensure the battery is in a well-ventilated area before commencing charging to prevent
the build-up of flammable gases.
IMPORTANT: This is an earthed device and must be connected to an earthed mains socket.
IMPORTANT: It is recommended to use this battery charger to charge only one battery at a time. Full
information regarding how to charge batteries in series or parallel with this charger is beyond the
scope of this manual. However, it is important to match: voltage, capacity, state of charge, relative
age and ideally brand and model of each battery to ensure correct charging for both series and
parallel. It is also important that battery banks have a final voltage of 6V or 12V and the combined
Ah rating is within the range stated in the specification.
WARNING: DO NOT switch polarity, for example negative clamp to positive battery terminal and
positive clamp to negative terminal. Doing so could cause damage to the device and the battery,
and could cause explosion.
Charging batteries
Note: Follow the correct procedure for either 'Connecting to a battery (in vehicle)' or 'Connecting to
a battery (freestanding)' before continuing.
1. Check that the clamps are securely connected to the correct terminals and will not loosen during
the charging process
2. Turn the automatic charger on at the power supply
3. Check the Battery Type Selector (5) is set to the correct battery and the Charge Start Selector (6) is
set to the required Charge Start mode (see 'Battery Type Selector' and 'Charge Start Selector' for
information)
• To cycle through the modes and selections using the Digital Display Selector (4), the Battery Type
Selector (5), or the Charge Start Selector (6), press the individual selector button repeatedly until
the light reaches the desired display mode/battery type/charge start mode
Note: Regularly monitor the charge level on the Digital Display (1) by checking the light next to
the charge level:
- Connected: battery detected and the battery charger is connected correctly
- Charging: the battery is charging correctly
- Charged: the battery has reached its full-charge capacity and the charger can now be switched
off then disconnected
• Once the battery reaches the desired amount of charge, or is fully charged, switch off the
automatic battery charger at the mains power source then disconnect the Black Negative Clamp
(8) followed by the Red Positive Clamp (9)
• When charging very cold batteries, the initial charge rate may increase as the battery warms. Do
not attempt to charge a frozen battery
• Internally damaged (shorted) batteries will draw very high current, without charging. If the
battery has been charging for 5¬–10 minutes and shows no reduction in charging current, the
battery may be damaged. Stop charging and have the battery professionally tested
• Refit battery in vehicle if removed, ensuring positive terminal is connected before the negative
terminal
IMPORTANT: Disconnect the charger from the mains power supply, then disconnect the battery after
use. Leaving the battery connected may result in overcharging and permanent battery damage.
Selecting 'Start' Mode
This mode briefly delivers 75A to bridge a drained or weak battery to assist in jump starting.
IMPORTANT: Only exit this mode by unplugging the Mains Power Cord (11).
WARNING: Ensure all of the connections are as described and are made in the correct
order, otherwise damage may occur to electronic systems in the vehicle. Proceeding against the
specifications in this manual is done with your own responsibility and at your own risk.
IMPORTANT: This function is not suitable for batteries that are below 45Ah as it could cause damage
to the batteries.
Note: To protect the battery from damage, the battery charger has a built-in analysis programme for
checking issues such as sulphation or rapid voltage drops. If the charger is connected to a severely
drained or heavily stressed battery it will not turn on. During this analysis process, the battery is
being charged with lower currents, which is indicated by the charging light, and the Digital Display
will read '0' . This means the Start mode function cannot be used, which will protect the battery from
damage. If this occurs, restart the automatic charger and then first charge the battery using either
the 'Fast Charge' or 'Normal Charge' modes. (See 'Charging Batteries' . )
Note: Diesel vehicles and large-volume engines require amperages above 75A for jump starting.
Charge the battery to at least 60% (monitor the 'Battery %' on the Digital Display (1)). Exit this mode
by unplugging the Mains Power Cord (11).
Automatic Battery Starter Charger 12A 6/12V
When using this mode:
- Ensure the battery has some charge; the automatic battery charger is not a jump starter but can
assist starting vehicles with partly depleted batteries by providing a boost
Note: For a quick charge to refresh a partially drained battery, charge the battery for 5–10 minutes
with the Battery Type Selector (5) set to the correct battery and the Charge Start Selector (6) set to
'Fast Charge' mode.
1. Ensure the vehicle's terminals are connected correctly to the battery terminals: positive '+' to
positive, and negative '-' to negative
2. Plug the battery charger's Mains Power Cord (11) in to the mains power
3. Connect the Red Positive Clamp (9) to the battery's positive '+' terminal
4. Connect the Black Negative Clamp (8) to the battery's negative '-' terminal
5. If connected correctly, the charger will automatically choose the correct battery type; however,
review this and change the battery type by cycling through the battery types and pressing the
Battery Type Selector (5) button
6. Select the 'Start' mode by pressing the Charge Start Selector (6) until the correct mode is selected
7. The Digital Display (1) should read '0'
8. Turn on the vehicle's ignition and attempt to start the vehicle, which will show a '5' on the Digital
Display and initiate a countdown: 2 seconds priming/analysis and 3 seconds jump start function
at 75A
9. During this countdown, the charger will briefly deliver 75A to bridge the battery to attempt to
start the car, which will be followed by a safety 180 second pause to protect the battery
10. After the pause, the 5 second cycle will restart followed by another pause
- Only do this for 5 cycles
- After 5 cycles, if the vehicle has not started, allow the battery to cool then revert to another charge
mode to charge the battery more before attempting the Start mode again
- After the vehicle has been started, select 'Alternator' mode on the Digital Display (1) to see if the
alternator is working. If the alternator reads 100, then it is working effectively. If it is not reading
100, there may be a problem with the vehicle's alternator and will need to be checked by a
professional mechanic as soon as possible
- If you are unable to start the vehicle after charging the battery again then using the 'Start' mode,
the battery might be faulty or there might be another mechanical fault with the vehicle. Seek
advice from a professional mechanic
Disconnecting from the battery
1. Remove the Black Negative Clamp (8) from the battery's negative '-' terminal
2. Remove the Red Positive Clamp (9) from the battery's positive '+' terminal
3. Unplug the Mains Power Cord (11)
4. Replace any covers for battery terminals/cells, if applicable
Note: If reconnecting the battery to the vehicle:
- reconnect the battery's positive '+' terminal
- reconnect the battery's negative '-' terminal
- replace any covers for battery terminals/cells, if applicable
