No.
The IC7 is a 12V battery charger only.
Do not use it on 6V or 24V batteries.
For GEL, AGM, WET and Calcium batteries, the IC7 uses a 7-stage charging process:
Desulphation — Breaks down sulphation in batteries that have been left flat.
Soft Start — Gently introduces power to the battery.
Bulk — Charges at maximum current up to the selected battery voltage.
Absorption — Charges the battery to full capacity using controlled voltage.
Analysis — Tests whether the battery has accepted charge.
Recondition — Attempts to restore batteries that cannot hold charge.
Float — Maintains the battery at 100% charge.
For Calcium mode, an Equalisation stage is also used.
When Lithium mode is selected, the IC7 uses a 5-stage lithium charging profile:
Soft Start 1 — Charges at 5% of selected current until the battery reaches 8.0V.
Soft Start 2 — Charges at 25% of selected current until the battery reaches 10.0V.
Bulk Charge — Charges at the selected current up to 14.2V.
Absorption — Completes charging at reduced current.
Float — Maintains the battery at 13.5V.
Yes.
Once the battery is fully charged, the charger moves into float mode and can remain connected to maintain the battery.
The selected battery chemistry should match the battery manufacturer’s recommendation.
Lithium: Maximum 14.2V
GEL: Maximum 14.1V
AGM: Maximum 14.4V
WET: 14.7V during bulk and absorption, up to 16V during recondition
Calcium: 14.7V during bulk and absorption, up to 16V during equalisation and recondition
The IC7 supports:

7A
Recommended guide:
1A: 7–20Ah deep cycle / 40–120CCA automotive / 55–170MCA marine / 2–10Ah lithium
2A: 14–40Ah deep cycle / 80–240CCA automotive / 110–330MCA marine / 4–20Ah lithium
4A: 30–80Ah deep cycle / 180–480CCA automotive / 250–650MCA marine / 8–40Ah lithium
7A: 50–140Ah deep cycle / 300–800CCA automotive / 350–900MCA marine / 14–70Ah lithium
Yes.
When Power Supply mode is selected, the IC7 provides a constant 13.8V DC output.
Power Supply mode can be used to run a load from the battery or to help maintain vehicle memory settings during battery replacement.
The connected appliance must not exceed the charger’s output current.
The charger may reset if the load exceeds the charger’s capacity or if the appliance has a high start-up current.
Reduce the load or connect the charger to a battery first, then run the appliance from the battery where possible.
Before using the IC7:
Read the instruction manual.
Use indoors only.
Do not expose the charger to rain.
Charge in a well-ventilated area.
Keep flames and sparks away from the battery.
Do not charge a frozen battery.
Do not charge a damaged or non-rechargeable battery.
Turn off vehicle accessories before charging where possible.
Disconnect the 240V mains supply before making or breaking battery connections.
Confirm the battery is a compatible 12V battery.
Most vehicles are negative earth.
The IC7 includes a wiring harness for easier connection to batteries that are difficult to access.
When disconnecting, unplug the harness from the charger output lead.
Yes.
The IC7 can be permanently wired using the supplied wiring harness.
Fuse requirement:
IC7: use supplied wiring harness with 15A fuse
The charger should be mounted indoors, out of weather, with at least 10cm clearance from the end plates for ventilation.
The IC7 uses LED indicators to show charge status.
Power LED — Red
Charging LED — Blue
Fully Charged LED — Green
Typical operation:
Blue Charging LED flashes or illuminates during charging stages.
Green Fully Charged LED solid means the battery is fully charged and the charger is in float mode.
Power LED flashing indicates a fault condition.
Check the following:
Battery voltage is above the minimum start voltage.
Battery clamps are connected correctly.
Red clamp is connected to positive +.
Black clamp is connected to negative – or correct chassis earth.
240V mains power is ON.
Correct battery chemistry is selected.
Correct charge rate is selected.
Battery is not frozen, damaged or faulty.
The specifications list a 2V minimum start voltage, while the FAQ section refers to charging from as little as 2.5V. If the battery is below this range, the charger may not start.
If the battery voltage is too low, the charger may not detect it.
The manual advises that booster cables can be used between two batteries to provide more than 2.5V to the battery being charged. Once the charger starts charging, the booster cables can be removed.
This should only be done by a competent person and only if the battery is safe to charge.
Desulphation mode is time limited to 6 hours and Soft Start is limited to 1 hour.
If required, Power Supply mode can be used for around 1 hour to raise the battery voltage. After that, select the correct battery chemistry to continue normal charging.
The charger can charge while an appliance is connected, but the load can affect the charger’s ability to accurately measure the battery.
For best charging, disconnect or turn off appliance loads.
If an appliance must remain connected, Power Supply mode is recommended.
Only select a different chemistry if the charge voltages match the battery manufacturer’s recommendation.
Do not select a higher voltage mode unless the battery manufacturer confirms it is suitable.
Calcium mode includes an Equalisation stage.
This can feed current into the battery until 16V is reached and may take up to 12 hours.
Fault:
Short circuit or reverse connection of the clips.
Recommended action:
Check the clips are not touching each other.
Check the clips are correctly connected to the battery.
Fault:
Bulk charging has timed out and stopped after 22 hours.
Recommended action:
Battery may be faulty.
Fault:
The charger has entered recondition mode 3 times and has timed out.
Recommended action:
Battery may be faulty and may need replacing.
There may be a load on the battery causing the battery to fail analysis.
Yes.
Press and hold the Charge Rate and Mode buttons together for 3 seconds until all LEDs illuminate.
This locks the Charge Rate and Mode keys.
To unlock, press and hold the Charge Rate and Mode buttons together again for 3 seconds until all LEDs illuminate.
