Safety Instructions

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

Wear safety glasses and gloves when working with batteries.
Ensure charger is unplugged from AC outlet before connecting to battery.
Connect red clamp to positive (+) battery terminal first, then black clamp to negative (-) terminal or grounded metal.
Plug charger into a grounded 120V AC outlet.
Keep charger away from water, rain, or moist conditions.

WARNING! Risk of explosion. Do not charge frozen or damaged batteries. Keep sparks and flames away from battery.

First-Time Setup

Unpack and inspect contents. Verify charger and cables are undamaged.

Select location: Dry, stable surface near battery but away from engine and moving parts.
Prepare battery: Clean terminals if corroded. Ensure battery is at room temperature.
Set battery type: Press "Battery Type" button to match your battery (Standard, AGM, Gel).
Connect clamps: RED to positive (+), BLACK to negative (-) or vehicle chassis.
Plug in AC power: Connect to 120V outlet. Charger will begin automatic diagnosis.

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

Controls and Indicators

Front Panel: Digital Display, Battery Type Buttons, Mode Button, Power/Status LEDs.

Display Readouts: Voltage (V), Amperage (A), Charge Mode (BULK, ABSORPTION, FLOAT), Error Codes.

LED Indicators: POWER (green), CHARGING (flashing green), COMPLETE (solid green), FAULT (red).

Buttons: BATTERY TYPE (cycle through Standard/AGM/Gel), MODE (toggle between 30A Fast Charge and 2A Maintenance).

Charging Procedure

Automatic charging for discharged or maintenance charging.

Verify battery voltage (display shows ~12.6V for full 12V battery).
Select correct battery type using BATTERY TYPE button.
For fast charge, ensure MODE is set to 30A. For trickle, select 2A.
Charger automatically progresses through stages:
- BULK: High-current charge until ~80% capacity.
- ABSORPTION: Voltage constant, current tapers.
- FLOAT: Maintains full charge without overcharging.
When COMPLETE LED lights, battery is fully charged. Unplug AC cord, then remove clamps (black first).

Tip: For deeply discharged batteries (<10V), charger may enter "recovery" mode with lower current.

Maintenance Mode

Use to maintain charge over long periods (winter storage, RVs, boats).

Connect clamps and plug in as normal.
Press MODE button until display shows "2A MAINT".
Charger will float charge, automatically topping off as needed.
Can be left connected indefinitely for battery maintenance.

Note: Maintenance mode is for 12V batteries only. Not for 6V applications.

Error Codes & Diagnostics

Display shows error codes if fault is detected.

Code	Meaning	Action
E1	Reverse Polarity	Check clamp connections (red to +, black to -)
E2	Overheat	Allow charger to cool; ensure ventilation
E3	Battery Voltage Too Low	Check battery (may be damaged or below 3V)
E4	Battery Voltage Too High	Disconnect; check for 24V battery or wiring issue
E5	Short Circuit / Bad Battery	Inspect battery and cables for damage

Care & Storage

Unplug and disconnect from battery before cleaning. Wipe with dry cloth; do not use liquids.

Store in dry location, away from extreme temperatures. Coil cables neatly to prevent damage.

CAUTION! Do not disassemble charger. No user-serviceable parts inside.

Regulatory Information

Troubleshooting

Symptom	Possible Cause	Corrective Action
Charger won't turn on	No AC power / Faulty outlet	Check outlet; try different circuit; ensure plug is secure
Display blank	Blown fuse / Internal fault	Check home fuse box; contact service if under warranty
Not charging / Low amps	Loose connections / Bad battery	Clean battery terminals; tighten clamps; test battery
Charger overheats	Blocked vents / High ambient temp	Ensure 6" clearance around vents; use in cooler area
Battery doesn't hold charge	Old or sulfated battery	Battery may need replacement; try recovery mode
Error code displayed	See Error Codes section	Refer to Section 9 for specific code instructions

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