Safety Instructions

Read all instructions before use. Use in well-ventilated area.

Wear eye protection and avoid flames/sparks near battery.
Ensure charger is unplugged before connecting to battery.
Connect clamps properly: RED to positive (+), BLACK to negative (-).
Do not charge frozen or damaged batteries.
Keep charger dry and away from liquids.

WARNING! Risk of explosion or acid burn. Follow instructions precisely. Do not disassemble charger.

Installation & Setup

Unpack and inspect contents. Place charger on stable, dry surface.

Power connection: Plug AC cord into 120V outlet after battery connection.
Battery connection: Ensure clamps make solid contact with battery terminals.
Automatic detection: Charger will detect battery voltage (6V/12V).
Mode selection: Choose charge rate (2A/6A/10A) based on battery size.

CAUTION! Connect clamps to battery before plugging into AC outlet. Disconnect in reverse order.

Charging Procedures

Automatic charging for 6V/12V batteries.

Preparation: Ensure battery terminals are clean and charger is unplugged.
Connection: Attach RED clamp to positive (+), BLACK clamp to negative (-).
Power On: Plug into AC outlet; display will show detected battery voltage.
Mode Selection: Press MODE to choose charge rate (2A for maintenance, 6A for standard, 10A for faster charge).
Monitoring: Display shows progress; charger automatically switches to float when complete.
Disconnect: Unplug AC cord, then remove BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries, charger may take several minutes to recognize battery before beginning charge cycle.

Maintenance Mode

Float/maintain mode keeps battery at optimal charge during storage.

Select 2A mode for maintenance charging.
Connect as normal; charger will complete charge cycle then switch to float.
Can be left connected indefinitely without overcharging.
Display shows "FLOAT" when in maintenance mode.

Note: Ideal for seasonal vehicles, boats, and equipment in storage.

Error Codes & Diagnostics

Display shows error codes for troubleshooting:

Code	Meaning	Action
E1	Reverse polarity detected	Check clamp connections
E2	Battery voltage too low/high	Check battery condition
E3	Overheating	Allow charger to cool
E4	Bad battery connection	Clean terminals, secure clamps
E5	Charger malfunction	Contact service center

Care & Storage

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

CAUTION! Do not expose to rain or moisture. Keep clamps clean and free of corrosion.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
No display/power	AC outlet dead/not plugged in	Check outlet; ensure plug is fully inserted
Charger not starting	Battery voltage too low	Try manual override mode; check battery
Error code displayed	See error code table	Refer to Error Codes section
Slow charging	Large battery/small charge rate	Select higher amp setting (6A or 10A)
Clamps heating	Poor connection	Clean battery terminals; ensure solid contact
Charger stops early	Battery defective/overheating	Test battery; allow to cool if hot

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