- Input Power Cord: Connects the charger to an AC power outlet.
- Output Cables: Connect to the battery via interchangeable connectors (clamps or O-rings).
- Ventilation Slots: Located on the casing to ensure proper heat dissipation.
Setup
Connecting to the Battery:
- Ensure Charger is Disconnected: Before making any connections, ensure the charger's AC power cord is unplugged from the wall outlet.
- Choose Connector Type: Select either the battery clamps or the O-ring terminal connectors based on your application.

The charger comes with both traditional battery clamps for temporary connections and O-ring terminals for more permanent installations, such as for trickle charging seasonal vehicles.
- Connect to Battery Terminals:
- Connect the RED (+) positive clamp/O-ring to the positive (+) battery terminal.
- Connect the BLACK (-) negative clamp/O-ring to the negative (-) battery terminal.
- Ensure connections are secure and clean.

Operating Instructions
Selecting a Charging Program:
The Absaar AB-PRO1 is a fully automatic charger with 9 charging stages. After connecting the charger to the battery and power, it will automatically detect the battery voltage (6V or 12V). You can use the "MODE" button to select specific charging programs if needed.
- Automatic Detection: The charger will typically detect if it's a 6V or 12V battery and begin the appropriate charging cycle.
- MODE Button: Press the "MODE" button to cycle through available charging programs. These may include:
- 12V STD: For standard 12V lead-acid batteries.
- 12V AGM: For 12V AGM (Absorbed Glass Mat) batteries.
- 12V Winter Mode: For optimal charging in low temperatures (below 5°C / 41°F).
- 6V STD: For standard 6V lead-acid batteries.
- LCD Display: The LCD display will show the current voltage, charging progress, and the selected mode.
- Charging Process: The charger will proceed through its 9-stage charging process, which includes desulfation, soft start, bulk charge, absorption, analysis, recondition, float, and pulse maintenance.
- Completion: The charger will automatically switch to maintenance (trickle charge) mode once the battery is fully charged, preventing overcharging. It can maintain batteries up to 120Ah.
Disconnecting the Charger:
- Unplug the AC power cord from the wall outlet first.
- Disconnect the BLACK (-) negative clamp/O-ring from the battery.
- Disconnect the RED (+) positive clamp/O-ring from the battery.
Maintenance
