User Manual for Amazon Basics 12V Battery Charger AB107

Quick guide from the manual

The Amazon Basics 12V Battery Charger (AB107) is designed for 6V and 12V lead-acid (STD or AGM) rechargeable batteries. It features an auto-start function, meaning the clamps will not spark when touched together until a battery is properly connected. Always ensure the area is well-ventilated and follow the specific connection steps to avoid sparks and potential battery explosions.

Important Safety Instructions

Risk of explosive gases: Lead-acid batteries generate explosive gases during normal operation. Follow these precautions:

• Keep out of reach of children.
• Do not expose the charger to rain or snow.
• Never smoke or allow sparks/flames near the battery or engine.
• Remove personal metal items like rings, bracelets, and watches when working near a lead-acid battery.
• Wear complete eye and clothing protection.
• If battery acid contacts skin or clothing, wash immediately with soap and water. If it enters eyes, flood with cold water for at least 10 minutes and seek medical attention.
• Never charge a frozen battery.

Preparing to Charge

Before connecting the charger, perform the following steps:

• If removing the battery from the vehicle, always remove the grounded terminal first.
• Ensure the area is well-ventilated.
• Clean battery terminals to prevent corrosion.
• Check battery voltage and ensure the charger is set to the correct voltage (the unit uses Auto Voltage Detection).
• If the battery has removable cell caps, add distilled water as specified by the manufacturer.

Troubleshooting

If you encounter issues, check the following:

• Clamps do not spark: This is normal; the charger has an auto-start feature and will not supply current until a battery is detected.
• Charger will not turn on: Check if the AC outlet is energized, check for loose connections, or have the battery checked as it may be defective.
• Yellow/orange LED flashing: The battery is not accepting a normal charge. Do not continue attempting to charge; check the battery and replace if necessary.
