2. Safety Information

Always prioritize safety when handling batteries. Batteries contain sulfuric acid, which can cause severe burns. They also produce explosive gases. Follow these precautions:

• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
• Ensure adequate ventilation when working with batteries.
• Keep sparks, flames, and smoking materials away from the battery.
• Avoid contact with battery acid. If contact occurs, flush immediately with water and seek medical attention.
• Do not short-circuit battery terminals.

3. Installation

Proper installation is crucial for optimal performance and safety. Refer to your vehicle's owner's manual for specific instructions and safety warnings before proceeding.

Battery Replacement Steps:

1. Preparation: Ensure the vehicle's ignition is off and all accessories are disconnected. Wear safety glasses and gloves.
2. Disconnect Negative Terminal: Locate the negative (-) battery terminal. Using an appropriate wrench, loosen the nut on the negative terminal clamp. Remove the negative cable and secure it away from the battery to prevent accidental contact.
3. Disconnect Positive Terminal: Locate the positive (+) battery terminal. Loosen the nut on the positive terminal clamp. Remove the positive cable and secure it away from the battery.
4. Remove Old Battery: Disconnect any battery hold-down clamps or straps. Carefully lift and remove the old battery from the vehicle. Be aware of its weight.
5. Clean Battery Tray: Inspect and clean the battery tray and terminal clamps to remove any corrosion or debris.
6. Install New Battery: Carefully place the OPTIMA 35 RedTop battery into the battery tray. Ensure it is seated securely.
7. Secure Battery: Reinstall and tighten the battery hold-down clamps or straps to prevent movement.
8. Connect Positive Terminal: Reconnect the positive (+) cable to the positive terminal. Tighten the clamp securely.
9. Connect Negative Terminal: Reconnect the negative (-) cable to the negative terminal. Tighten the clamp securely.
10. Final Check: Verify all connections are tight and secure. Ensure no tools or loose items are left in the engine compartment.

• Consistent Performance: Maintains high voltage longer during discharge, ensuring consistent power delivery.

5. Maintenance

The OPTIMA 35 RedTop battery is a sealed AGM (Absorbed Glass Mat) battery, making it maintenance-free. This means there is no need to add water or perform routine electrolyte checks.

Maintenance Guidelines:

• Cleaning: Keep the battery terminals and top clean and free of corrosion. Use a mixture of baking soda and water to clean terminals if necessary, then rinse with clean water and dry thoroughly.
• Terminal Connections: Periodically check that terminal connections remain tight and secure.
• Charging: If the vehicle is stored for extended periods or used infrequently, consider using a compatible battery maintainer to keep the battery fully charged.
• Vibration: The battery is designed with high vibration resistance, but ensure it is always securely mounted to minimize excessive movement.

6. Troubleshooting

If you experience issues with your OPTIMA 35 RedTop battery, consider the following general troubleshooting steps:

• No Start/Slow Crank: Check all battery cable connections to ensure they are clean, tight, and free of corrosion. Verify the battery's state of charge using a voltmeter. A fully charged 12-volt battery should read approximately 12.6-12.8 volts.
• Accessory Malfunction: Ensure the battery is adequately charged and connections are secure. Check vehicle fuses related to the malfunctioning accessories.
• Battery Not Holding Charge: Confirm the vehicle's charging system (alternator) is functioning correctly. If the charging system is fine, the battery may require professional testing or replacement.

For persistent issues, it is recommended to consult a qualified automotive technician or OPTIMA Batteries customer support.
