Safety Precautions

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

Work in a well-ventilated area. Batteries generate explosive gases.
Wear safety glasses and gloves. Battery acid can cause severe burns.
Do not charge frozen or damaged batteries.
Ensure charger is unplugged from AC power before connecting/disconnecting clamps.
Connect RED clamp to POSITIVE (+) terminal first, then BLACK to NEGATIVE (-).
Keep charger dry and away from flammable materials.

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

Installation & Initial Setup

Unpack charger and inspect for damage. Ensure work area is clean, dry, and well-ventilated.

Place charger on stable, non-flammable surface near battery.
Plug AC power cord into grounded 120V outlet. Do not turn on yet.
Select battery voltage (6V or 12V) using the VOLTAGE button.
Select battery type (Standard, AGM, Gel, Deep-Cycle) using TYPE button.
Connect clamps to battery terminals: RED to POSITIVE (+), BLACK to NEGATIVE (-) or vehicle chassis ground.
Once securely connected, the display will illuminate and show battery status.

CAUTION! Never connect clamps to each other or allow them to touch metal surfaces other than intended terminals.

Charging Procedures

For 12V Standard Automotive Battery (typical use):

Ensure charger is unplugged from AC outlet.
Set VOLTAGE to 12V. Set TYPE to STANDARD (or match your battery type).
Connect clamps: RED to battery positive (+), BLACK to negative (-) or chassis ground.
Plug charger into AC outlet. Display will light up and show battery voltage.
Press POWER button to begin automatic charging sequence.
Display will show charging progress (%, amps). When fully charged, display will show "FULL" and switch to Float Maintenance mode.
To disconnect: Unplug AC cord first, then remove BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries (<2V), charger may enter Recondition mode automatically or display an error. Refer to troubleshooting.

Battery Reconditioning Mode

Use for sulfated or deeply discharged batteries that won't hold a charge.

Connect charger to battery following standard safety steps.
Set correct voltage and battery type.
Press MODE button until "RECONDITION" appears on display.
Press ENTER to start. Process can take 8-24 hours.
Charger will apply a controlled desulfation pulse, then attempt a full charge cycle.
Monitor display. If battery cannot be recovered, "FAULT" or "BAD BATTERY" may appear.

WARNING! Reconditioning may not revive all batteries. Do not leave unattended for extended periods.

Maintenance & Storage

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

Wipe casing with dry cloth. Do not use liquids or solvents.
Inspect clamps and cords for damage before each use.
Coil cords neatly using integrated storage hooks.
Store in original box or protective case if available.

CAUTION! Do not expose to rain, snow, or excessive moisture. Do not store near heat sources.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Display blank/no power	AC outlet dead, cord not plugged in	Check outlet with another device; ensure AC cord fully inserted.
"REV POL" or reverse polarity error	Clamps connected backwards	Disconnect immediately. Connect RED to positive (+), BLACK to negative (-).
"BAD BATTERY" or "FAULT"	Battery voltage too low, damaged, or shorted	Check battery voltage with multimeter. Try Recondition mode. Replace battery if faulty.
Charger stops quickly/overheats	High ambient temperature, blocked vents	Move to cooler area; ensure vents are clear; allow to cool before restarting.
Not charging/maintaining	Loose connections, corroded terminals	Clean battery terminals; ensure clamps have solid metal-to-metal contact.
Display shows incorrect voltage	Battery type setting wrong, poor connection	Verify battery type selection; disconnect and reconnect clamps securely.

Reset: Unplug from AC and battery for 2 minutes, then reconnect.
