2. Safety Information

Always read and understand all safety warnings and instructions before using the OptiMate 7 charger. Failure to do so may result in electric shock, fire, or serious injury.

• Use the charger only for 12V or 24V lead-acid batteries (AGM, Wet, EFB, Spiral Cell, Gel). Do not use for other battery types.
• Ensure proper ventilation during charging. Do not charge in a sealed area.
• Avoid sparks or flames near the battery. Batteries can produce explosive gases.
• Wear eye protection and protective clothing when working with batteries.
• Keep out of reach of children.
• Do not expose the charger to rain or excessive moisture.
• Disconnect the AC power before making or breaking connections to the battery.
• If the battery is completely dead or internally shorted, the OptiMate charger cannot revive it. Such batteries require replacement.
• If the green LED indicates full charge but the engine does not start, a minor internal short in the battery may be present. The OptiMate charger may not detect such minor shorts, and the battery will require replacement.

5. Setup

Follow these steps to set up your OptiMate 7 charger:

1. Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If charging a wet cell battery, check electrolyte levels and top up with distilled water if necessary.
2. Connect to Battery: Choose either the ring terminal cable for permanent installation or the alligator clip cable for temporary connection. Connect the red (+) clamp/terminal to the positive (+) battery terminal and the black (-) clamp/terminal to the negative (-) battery terminal. Ensure a secure connection.
3. Connect to Power: Plug the AC power cord of the OptiMate 7 into a standard wall outlet.

The charger will automatically begin its diagnostic and charging process. The battery can remain in the vehicle during charging.

6. Operating Instructions

The OptiMate 7 features an intelligent multi-step charging program. Once connected, it automatically diagnoses the battery and proceeds through the charging stages.

6.1 Charging Process Overview

• Diagnosis: The charger first checks the battery's voltage and overall health.
• Desulfation (if needed): If a deeply discharged or sulfated battery is detected, the pulse recovery mode activates to break down lead sulfate crystals.
• Bulk Charge: Delivers maximum current to bring the battery to approximately 80% charge.
• Absorption Charge: Gradually reduces current while increasing voltage to fully charge the battery.
• Verification: Checks if the battery can retain charge.
• Maintenance: Once fully charged, the charger enters a long-term maintenance mode, delivering small charges as needed to counteract self-discharge.

6.2 Mode Selection (12V / 24V and Voltage Options)

The OptiMate 7 allows selection between 12V and 24V charging, and offers specific voltage settings for different battery types:

• Use the 'SELECT' dial on the charger to choose the appropriate voltage (12V or 24V) and charging mode for your battery.
• For 12V Batteries:
  • 14.4V: For standard lead-acid batteries.
  • 14.7V: For general deep cycle batteries.
  • 15.0V: For Optima, Voyager, and other spiral cell type batteries.
• For 24V Batteries:
  • 28.8V: For standard 24V lead-acid batteries.
  • 29.4V: For general 24V deep cycle batteries.
  • 30.0V: For 24V Optima, Voyager, and other spiral cell type batteries.

7. Maintenance

The OptiMate 7 is designed for long-term battery maintenance, ensuring your battery remains in optimal condition, especially during periods of non-use.

• Connect and Forget: The 24/7 maintenance function allows you to leave the charger connected to the battery indefinitely. It will automatically monitor the battery's state and deliver small, precise charges to prevent self-discharge.
• Pulse Recovery: The powerful pulse recovery feature helps to reverse sulfation, a common cause of battery failure, by dissolving lead sulfate crystals that build up on battery plates. This can extend battery life.
• Battery Health Monitoring: The charger continuously monitors the battery's health and provides feedback through its LED indicators. A green LED indicates a healthy, fully charged battery.

8. Troubleshooting

If you encounter issues with your OptiMate 7 charger, refer to the following common problems and solutions:

• Charger does not start: Ensure the AC power cord is securely plugged into a live outlet and the battery connections are correct (red to positive, black to negative).
• Battery does not charge / Charger indicates error:
  • Check battery voltage. If the battery is completely dead (e.g., 0V), the charger may not be able to initiate charging.
  • Important Note 1: The OptiMate charger cannot revive batteries that have reached the end of their service life or have an internal short circuit. If an internal short occurs, no charger can revive it, and the battery must be replaced.
• Green LED is on, but engine won't start:
  • Important Note 2: If the green LED indicates a full charge but the engine still won't start, a minor internal short may be present within the battery. While the surface voltage may appear normal, it drops sharply during engine cranking, preventing startup. The OptiMate charger's battery health diagnosis is a guideline and may not detect such minor internal shorts. In such cases, the battery requires replacement as internal shorts cannot be repaired by a charger.
• Unusual heat or smell: Immediately disconnect the charger from both the AC outlet and the battery. Contact customer support.
