Operation Guidelines

• Not intended for use as a DC power supply.
• Ensure operation in an environment with proper ventilation.
• Avoid operating in damp or wet conditions.

LED Status Indicator Light

• LED1 (Left): RED – AC power connected, Power Switch ON.
• LED2 (Right): YELLOW – Charging (Bulk and Absorption stages), Fan ON.
• LED2 (Right): GREEN – Battery Charged (Maintenance Float mode), Fan OFF.

Important Note: If LED2 shows GREEN when initially connected to a known discharged battery (instead of YELLOW), there is an output connection fault. Check for:

1. Charger not connected.
2. Minimum battery voltage not sensed (8V minimum).
3. Output fuse blown (inspect fuse under twist cap).

Recommended Usage

For optimal performance, ensure the charger's amperage output matches approximately 10-15% of the AH capacity of the battery being charged. For instance, this 7 amp charger is best suited for batteries with a maximum AH capacity in the 70AH-105AH range. Chargers with insufficient output ratings may result in excessively long charging times.
