Safety Instructions

Read all instructions before use. Use charger only with lead-acid batteries.

Work in well-ventilated area: Batteries produce explosive gases.
Wear eye protection: Protect eyes from battery acid and sparks.
Disconnect AC power before connecting/disconnecting battery clamps.
Connect clamps correctly: RED to positive (+), BLACK to negative (-).
Do not charge frozen or damaged batteries.

WARNING! Risk of explosion or electric shock. Follow all safety precautions. Keep away from children.

Installation & Setup

Unpack and inspect contents. Ensure charger is unplugged from AC outlet.

Prepare battery: Clean terminals if corroded. Ensure battery is in well-ventilated area.
Connect clamps: First connect RED clamp to positive (+) terminal. Then connect BLACK clamp to negative (-) terminal or vehicle chassis.
Plug into AC power: Insert charger plug into 120V AC, 60Hz outlet.
Select mode (if applicable): Press MODE button to choose between 6V, 12V, or AGM/GEL (if model has manual selection).

CAUTION! Never connect clamps in reverse order. Ensure secure connections to prevent sparking.

Charging Procedure

Charger operates automatically once connected properly.

Verify connections: RED to positive, BLACK to negative.
Plug into AC outlet: POWER light should illuminate.
Monitor display: Shows battery voltage and charging stage.
Bulk charging: High current until ~80% charged.
Absorption charging: Voltage constant, current tapers.
Float/maintenance: Maintains full charge without overcharging.
Completion: FULL light illuminates; charger switches to maintenance mode.
Disconnect: Unplug AC power first, then remove BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries, charger may take several hours. If FAULT light appears, check connections and battery condition.

Maintenance & Storage

Unplug and clean after each use. Store in dry, cool location.

Clean clamps: Wipe with dry cloth to prevent corrosion.
Inspect cables: Check for cracks or exposed wires.
Store properly: Coil cords neatly; avoid extreme temperatures.
Maintenance charging: Use periodically to maintain stored batteries.

CAUTION! Do not immerse charger in water. Keep ventilation openings clear of debris.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power/display	AC outlet dead; cord not plugged in	Test outlet; ensure plug is fully inserted; check circuit breaker.
FAULT light on	Reverse connection; bad battery	Disconnect and reconnect clamps correctly; test battery voltage.
Not charging	Loose clamps; sulfated battery	Secure connections; try charging on 12V setting if automatic detection fails.
Charger shuts off quickly	Battery fully charged; high resistance	Check battery voltage; clean terminals; ensure good contact.
Display shows error code	Refer to manual code list	E01: Reverse polarity; E02: Over voltage; E03: Over temperature.

Reset: Unplug from AC and battery for 5 minutes, then reconnect.
