Controls and Indicators

Front Panel: Voltage selector switch, LED status indicator, Power cord input.

LED Indicator Colors:

Red (Flashing): Reverse polarity detected - Disconnect immediately
Red (Solid): Bulk charging stage (0-80% charge)
Yellow (Solid): Absorption stage (80-100% charge)
Green (Solid): Float/Maintenance mode (100% charged, maintaining)
Green (Flashing): Battery fully charged and maintaining
No Light: No power or fault condition

Voltage Selector: Slide switch to select between 12V and 24V operation.

Charging Process

The 4-stage charging process optimizes battery life and performance:

Bulk Stage: Delivers maximum current (10A) until battery reaches 80% charge (Red LED)
Absorption Stage: Voltage constant, current tapers as battery reaches 100% (Yellow LED)
Float Stage: Maintains battery at full charge with reduced voltage (Green LED solid)
Maintenance Mode: Monitors battery and provides pulses as needed (Green LED flashing)

Note: Total charging time varies based on battery size and discharge level. A completely dead 100Ah battery may take 10+ hours.

Connecting to Batteries

Proper connection sequence is critical for safety:

Turn off all loads and ignition if charging vehicle battery.
Set voltage selector to match battery system (12V or 24V).
Connect RED clamp to positive (+) battery terminal.
Connect BLACK clamp to negative (-) battery terminal or clean chassis ground.
Plug AC cord into grounded outlet.
Observe LED - if flashing red, disconnect immediately and check polarity.

Tip: For batteries in vehicles, connect negative clamp to engine block or chassis away from battery.

Maintenance Mode

After full charge, charger enters maintenance mode (Green flashing LED). In this mode:

Charger monitors battery voltage
Provides small pulses when voltage drops below threshold
Keeps battery at optimal charge indefinitely
Prevents overcharging and sulfation

Ideal for seasonal storage of vehicles, boats, RVs, and equipment.

Safety Features

Multiple protections ensure safe operation:

Reverse Polarity Protection: Prevents damage if clamps reversed
Spark-Proof: No sparks when connecting clamps
Short-Circuit Protection: Shuts down output if short detected
Over-Temperature Protection: Reduces current if charger overheats
Over-Charge Protection: Prevents battery damage from overcharging
Automatic Voltage Detection: Prevents charging if battery voltage too low

CAUTION! Always charge in well-ventilated area. Batteries produce explosive gases.

Care & Storage

Unplug from AC power and disconnect from battery before cleaning. Wipe with dry cloth only.

Storage: Store in cool, dry place. Keep clamps from touching each other.

CAUTION! Do not expose to water or liquids. Do not disassemble charger.

Troubleshooting

Symptom	Possible Cause	Corrective Action
LED flashing red	Reverse polarity connection	Disconnect immediately. Check and correct clamp connections.
No LED light	No AC power / Fault	Check outlet; ensure plugged in. Reset by unplugging for 30 seconds.
LED stays red	Battery deeply discharged	Allow more time for charging. If >24 hours, battery may be damaged.
Charger gets hot	Normal during bulk charge	Ensure ventilation. If excessively hot, disconnect and let cool.
Not charging	Bad connections / Dead battery	Clean battery terminals. Test battery voltage (below 3V may not charge).
LED cycles colors	Fault condition	Disconnect, wait 1 minute, reconnect. If persists, contact support.

Reset: Unplug from AC power and battery for 30 seconds to reset.
