Safety Precautions

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

Work in well-ventilated area: Batteries produce explosive gases.
Wear eye protection: Shield eyes when working near batteries.
Remove jewelry: Avoid short circuits.
Check battery condition: Do not charge damaged, leaking, or frozen batteries.
Disconnect AC power before connecting/disconnecting clamps.

WARNING! Risk of explosion or acid burn. Follow instructions precisely. Keep away from children.

First-Time Setup

Charging Procedure

For 6V or 12V lead-acid batteries.

Ensure battery is in well-ventilated area.
Clean battery terminals if corroded.
Set battery type switch correctly.
Connect RED clamp to positive (+) terminal first.
Connect BLACK clamp to negative (-) terminal or vehicle chassis.
Plug charger into AC outlet.
Charger will beep once and display detected voltage.
Charging begins automatically; display shows progress.
When fully charged, display shows "FULL" and green light stays on.
Unplug AC cord, then disconnect BLACK clamp, then RED clamp.

Tip: For deeply discharged batteries, charger may take several hours. Do not leave unattended for extended periods.

Maintenance Mode

Keeps stored batteries at full charge.

Connect charger to battery as normal.
Press MODE button until "MAINT" appears on display.
Charger will maintain battery with float voltage, preventing sulfation.
Can be left connected for weeks; charger cycles on/off automatically.
To exit, press MODE button or disconnect power.

WARNING! Check battery electrolyte levels monthly if applicable. Do not use Maintenance mode on damaged batteries.

Care & Storage

Unplug and disconnect before cleaning. Wipe with dry cloth; keep vents clear.

Storage: Store in cool, dry place. Coil cords neatly. Keep away from metal objects to prevent short circuits.

CAUTION! Do not expose to rain or moisture. Do not disassemble charger.
