3. Setup

1. Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If necessary, clean them with a wire brush.
2. Select Terminal Type: Choose between the clamp terminals or the O-ring terminals based on your application.
   • Clamp Terminals: Ideal for temporary connections or batteries not easily accessible for O-ring installation.
   • O-Ring Terminals: Suitable for semi-permanent installations, often bolted directly to battery posts.
3. Connect to Battery (Maintainer Disconnected from AC Power):
   • Connect the RED (+) terminal (clamp or O-ring) to the POSITIVE (+) battery post.
   • Connect the BLACK (-) terminal (clamp or O-ring) to the NEGATIVE (-) battery post.

   Ensure connections are secure and make good contact.
4. Connect to AC Power: Once the battery connections are secure, plug the maintainer's AC power cord into a standard 120V AC electrical outlet.

4. Operating Instructions

The Strongway Battery Maintainer features intelligent automatic charging and a simple interface.

1. Initial Power On: Once plugged into AC power and connected to the battery, the maintainer will automatically detect the battery voltage (6V or 12V).
2. Voltage Selection:
   • The corresponding 6V or 12V LED indicator on the unit will illuminate.
   • If the detected voltage is incorrect, press the "SELECT VOLTAGE" button (power symbol) to toggle between 6V and 12V modes. The active voltage will be indicated by the illuminated LED.
3. Charging Process: The maintainer will begin its 7-stage charging process. This process automatically adjusts the charging current and voltage to optimize battery health and prevent overcharging. The LEDs will indicate the current status:
   • 6V/12V LED (Green): Solid green indicates the selected voltage and that charging is active or the battery is being maintained.
   • Error LED (Red): If this LED illuminates, refer to the Troubleshooting section.
4. Float Maintenance: Once the battery is fully charged, the maintainer will automatically switch to float maintenance mode. In this mode, it provides a small, continuous current to keep the battery at optimal charge without overcharging, making it safe for long-term connection.
5. Disconnecting: To disconnect the maintainer, first unplug the AC power cord from the wall outlet, then disconnect the battery leads (black negative first, then red positive).

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your Strongway Battery Maintainer.

• Cleaning: Periodically wipe the exterior of the maintainer with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Connections: Regularly inspect the battery terminals and quick-connect cables for any signs of corrosion, damage, or loose connections. Ensure they are clean and secure.
• Storage: When not in use, store the maintainer in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cable Inspection: Check the AC power cord and battery cables for cuts, fraying, or damage. Do not use the unit if any cables are compromised.
