The IC25 is a 12V battery charger only.
For 24V applications, use a suitable 24V charger such as the IC8-24.
For GEL, AGM, WET and Calcium batteries, the IC25 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 IC25 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.
The IC25 includes the following battery chemistry modes:
Lithium
GEL
AGM
WET
Calcium
Power Supply
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
Power Supply: 13.8V constant voltage
The selected chemistry should match the battery manufacturer’s recommendation.

Power Supply mode is designed to operate as a float charge to maintain a battery while a load or appliance is running from the battery.
Power Supply mode will only operate when connected to a battery.
In Power Supply mode, the charger can output up to 13.8V on 12V models.
Recondition mode can help restore batteries that have been deeply discharged by equalising the cells.
The manual states that Recondition mode runs for 4 hours. When complete, the charger will continue with a normal charge cycle.
Use Recondition mode only when suitable for the battery type and when the battery manufacturer allows it.
The manual advises removing the battery from the vehicle before using Recondition mode to prevent electrolyte spillover from damaging the vehicle or engine bay.
Yes.
The IC25 supports a remote control display.
The remote display allows the charger to be monitored and controlled when the charger is mounted out of sight.
Yes.
The temperature sensor monitors battery temperature and adjusts the charger output to help prevent overcharging.
The temperature sensor ring terminal should be installed to the negative battery terminal.
Before using the IC25:
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.
Yes.
The IC25 can be hard wired to the battery for permanent installations.
Recommended fuse or circuit breaker rating:
IC25: 30A
Important note:
The charger DC leads include sensor wires running parallel to the positive and negative DC leads. These are used for accurate voltage measurement directly at the battery.
It is strongly recommended not to cut the DC leads. If the leads are cut, the sensor wires must be included in both the positive and negative battery connections.
The LCD screen normally displays battery voltage.
Press the VOLTS/AMPS button to view input current.
During Equalisation and Recondition, the LCD screen may display rapid horizontal scrolling lines.

Check the following:
Battery voltage is above 1.0V.
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.
Charger On/Off switch is ON.
Correct battery chemistry is selected.
Correct charge rate is selected.
Battery is not frozen, damaged or faulty.
The IC25 is designed to charge from as little as 1.0V on 12V batteries.
If the battery is below 1.0V, the charger may not detect it.
The manual advises that booster cables can be used between two batteries to provide more than 1.0V 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.
The charger can charge while an appliance is connected, but the load can affect the charger’s ability to accurately measure battery response.
For best charging, disconnect or turn off appliance loads.
If an appliance must remain connected, Power Supply mode is recommended.
Calcium mode includes an Equalisation stage.
This can feed current into the battery until 16V is reached and may take up to 12 hours.
