New Improved PCB Board that makes car battery charger More Durable and not easily prone to damage.

This item is tested to be compliance with the IEC AS/NZS 60335.2.29:2017 + A1 & AS/NZS 60335.1:2020 with Australia and New Zealand deviation.

Step 1: Diagnostic
Battery Charger checks the battery status and detects the voltage.

Step 2: Recovery
If a deeply discharged battery's voltage is over 4.5V ± 0.5V (for 12V battery) or 16V ± 0.25V (for 24V battery), charger begins charging with 1.5A low current to recover it, which terminates when voltage reaches to 10.5V ± 0.25V for (12V battery) or 21V ± 0.25V (for 24V battery) at the beginning of the process, the charger skips low current charging and it switches over to charging mode.

Step 3: Soft start
The charger checks and tests if the battery can accept charge. This prevents charging with a defective battery.

Step 4: Bulk Charge
80% of energy is returned in this phase of charging. 24V Battery: Select 2A slow charge or 5A medium charge rate according to your need. 12V Battery: Select 2A slow charge, 5A medium charge and 10A fast charge rate according to your need.

Step 5: Absorption (80-90% charging)
A constant low charging current is given at 1.5A to raise voltage from 28.2V to 28.8V (for 24V battery) and 14.1V to 14.4V (for 12V battery).

Step 6: Spontaneous selection of Charging Voltage
1.5A－10A－7.5A－5A－4A－3A－2A－1.5A 13.6V/5A
The charger will automatically select the right voltage according to the battery voltage type, and then the corresponding LED indicator will turn on.

Step 7: Trickle (90-100% charging)
In this phase complete charging up to almost 100% is reached. Charger switches to trickle charge phase after identifying that the battery is fully charged.

Step 8: Maintenance
The charger continuously monitors the terminal voltage in order to determine if a maintenance charging should be initiated. The charger starts maintenance charging pulse at constant 1.5A if the battery is loaded and/or terminal voltage falls below 25.6V (for 24V battery) or 12.8V (for 12V battery).

Step 9: 13.6V Power supply
If this mode is activated, you can use the charger as a Power Supply to provide constant power to 12V DC appliances with 5A(max) output current.
