Safety Instructions

Read all instructions before use. For lead-acid batteries only.

Work in well-ventilated area: Batteries generate explosive gases.
Wear eye protection: Battery acid can cause severe injury.
Check battery condition: Do not charge damaged, leaking, or frozen batteries.
Disconnect AC power before connecting/disconnecting battery clamps.
Connect clamps properly: RED to positive (+), BLACK to negative (-).

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

First-Time Setup

Unpack charger and inspect for damage. Verify battery type and voltage.

Prepare battery: Clean terminals and ensure vent caps are secure (if applicable).
Connect charger: Plug AC cord into outlet. DO NOT connect to battery yet.
Attach clamps: Connect RED clamp to positive (+) terminal, BLACK to negative (-).
Select mode: Press MODE button to choose between 6V, 12V, or AGM if manual selection required.
Begin charging: Charger will automatically detect voltage and begin appropriate charge cycle.

CAUTION! Never connect clamps to each other. Ensure proper polarity to avoid damage.

Specifications

Input Voltage: 120V AC, 60Hz.
Output Voltage: 6V/12V DC automatic selection.
Charge Rate: 1.5A for 6V, 3A for 12V (maximum).
Battery Types: Standard flooded, AGM, gel-cell, deep-cycle.
Charging Stages: 3-stage (Bulk, Absorption, Float).
Display: Digital LCD showing voltage, current, and status codes.
Protections: Reverse polarity, short circuit, overheat, overcharge.
Dimensions: 7.5" x 3.5" x 2.25".

Controls and Display

Front Panel: MODE button, Display, Status LEDs (Charging, Maintenance, Fault).

Display Information: Shows battery voltage (e.g., 12.5V), charge current (e.g., 2.1A), and status indicators.

Mode Selection: Automatic detection default. Manual mode: Press MODE to cycle 6V → 12V → AGM → Auto. Status LEDs: CHARGING (red), MAINTENANCE (green), FAULT (flashing red). Display Codes: "FUL" (fully charged), "ERR" (error detected), "LO" (low voltage), "HI" (high voltage).

Charging Procedures

Automatic charging for most batteries. Manual selection available.

Ensure battery is in safe, well-ventilated location.
Connect AC power to outlet (charger should remain off).
Connect clamps: RED to positive, BLACK to negative terminal or grounded metal.
Charger will automatically begin analysis and charging cycle.
Monitor display: Shows current stage and progress.
Completion: Charger switches to maintenance mode automatically.
Disconnect: Unplug AC power, then remove BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries (< 2V), charger may display "LO" and not start. Try manual mode or consult troubleshooting.

Maintenance Mode

After full charge, charger switches to float maintenance (trickle charge).

Maintenance voltage: 13.4V for 12V, 6.7V for 6V batteries.
Keeps battery at optimal charge during storage.
Can be left connected indefinitely without overcharging.
Green MAINTENANCE LED indicates active float mode.

Note: For seasonal storage, connect charger every 30-60 days for 24-48 hours.

Error Codes & Diagnostics

Display shows error codes for specific conditions.

Code	Meaning	Action
ERR	General fault	Check connections; disconnect and restart
LO	Battery voltage too low (< 2V)	Try manual mode; battery may be damaged
HI	Battery voltage too high (> 18V)	Check battery; may be overcharged
HOT	Charger overheated	Allow to cool in ventilated area
REV	Reverse polarity detected	Disconnect and correct clamp connections

Care & Storage

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

Clean clamps with baking soda solution if corroded.
Wipe casing with dry cloth; do not use liquids.
Coil cords neatly to prevent damage.
Store in original box or protective case.

CAUTION! Do not expose to rain or moisture. Do not store near heat sources or flammable materials.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Charger won't turn on	No AC power	Check outlet; ensure AC cord fully inserted
Display shows "ERR"	Faulty connection	Disconnect all cables, restart, ensure clean terminals
Not charging	Deeply discharged battery	Try manual mode; battery may need replacement
Clamps sparking	Connection sequence wrong	Connect clamps before plugging in AC power
Overheating	Poor ventilation	Move to cooler area; ensure fan vents unobstructed
Wrong voltage detected	Battery below 2V	Use manual voltage selection; test battery

Reset: Unplug AC power, disconnect clamps, wait 60 seconds, restart.
