Safety Instructions

Read all instructions before use. Charger produces hydrogen gas—keep away from flames/sparks.

Use in well-ventilated area. Do not cover charger during operation.
Wear eye protection. Avoid touching battery acid.
Connect to AC power only after clamps are securely attached to battery.
Do not charge frozen or damaged batteries.
Keep children and pets away from charger and battery.

WARNING! Risk of explosion or electric shock. Follow all safety precautions. Do not disassemble charger.

Installation & Setup

Unpack and inspect contents. Ensure battery is in a stable, dry location.

Prepare battery: Clean terminals if corroded. Ensure vent caps are secure (if applicable).
Connect clamps: FIRST attach RED clamp to POSITIVE (+) battery terminal. THEN attach BLACK clamp to NEGATIVE (-) terminal or grounded metal on vehicle frame.
Plug into AC outlet: Use a grounded 120V, 60Hz outlet. Charger will automatically begin analysis.
Monitor LEDs: Refer to indicator chart for charging status.

CAUTION! Always connect clamps in the specified order to prevent sparks. Ensure clamps have firm contact.

Controls and Indicators

LED Indicator Panel: Provides visual status of the charging process.

LED Status Guide:

POWER (Green): Solid = AC power connected.
CHARGING (Red): Flashing = Bulk/Absorption stage in progress.
MAINTAINING (Green): Solid = Float/maintenance mode active.
FAULT (Red): Solid = Error detected (reverse connection, bad battery, overheat).
BATTERY TYPE (Amber): Solid = AGM/Gel mode selected (if applicable).

Buttons: MODE button (if equipped) toggles between standard and AGM/Gel charging profiles.

Charging Procedure

For a standard 12V automotive battery.

Ensure vehicle ignition and all accessories are OFF.
Connect clamps in correct order (RED first to +, BLACK to - or chassis ground).
Plug charger into AC outlet. The POWER LED will illuminate.
Charger will analyze battery: If voltage is very low, it may enter Recondition mode first.
CHARGING LED will flash during bulk/absorption stages.
When battery is nearly full, charger switches to float/maintenance (MAINTAINING LED solid green).
To disconnect: Unplug AC cord first, then remove BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries (<2V), charger may take several minutes to initiate. Be patient.

Maintenance Mode

The charger automatically enters float/maintenance mode after the battery is fully charged. This trickle charge keeps the battery at optimal voltage for long-term storage (e.g., winter, boats, RVs).

Leave connected indefinitely for battery maintenance.
Charger will cycle on/off to prevent overcharging.
Ideal for seasonal vehicles or infrequently used equipment.

Note: Always check battery electrolyte levels (on flooded batteries) before long-term maintenance charging.

Care & Storage

Unplug and disconnect from battery before cleaning. Wipe with a dry cloth. Store in a cool, dry place.

CAUTION! Do not expose to rain, snow, or liquids. Do not store near heat sources or flammable materials. Coil cords neatly to prevent damage.

Troubleshooting

Symptom	Possible Cause	Corrective Action
POWER LED not on	No AC power	Check outlet; ensure plug is fully inserted; try different outlet.
FAULT LED solid red	Reverse connection / Bad battery	Disconnect and reconnect clamps correctly. Test battery voltage. Replace if below 2V or defective.
CHARGING LED not flashing	Deeply discharged battery	Wait up to 30 mins for reconditioning to start. If no change, battery may be unusable.
Charger gets warm/hot	Normal operation / Overload	Some warmth is normal. If excessively hot, unplug, let cool, check for blocked vents.
Battery not holding charge	Old/damaged battery	Battery may be at end of life. Have battery tested at an auto parts store.
Spark when connecting	Clamp order incorrect / Accessories on	Ensure ignition and all loads are OFF. Always connect RED clamp first.

Reset: Unplug from AC and battery for 2 minutes to reset microprocessor.
