Important Notices
Observe Correct Polarity: Before connecting the battery, verify that the positive (+) and negative (-) terminals are properly aligned. Reversed polarity may cause permanent damage to the battery and connected equipment.
Install in a Dry and Ventilated Area: The battery should be installed in a clean, dry, and well-ventilated environment away from direct sunlight, water, excessive humidity, and corrosive substances.
Avoid Extreme Temperatures: For best performance and battery life, operate and store the battery within the recommended temperature range. Exposure to extreme heat or freezing temperatures may affect battery performance.
Secure the Battery Properly: Ensure the battery is firmly mounted during installation, especially in RV, marine, and mobile applications, to prevent movement, vibration damage, or loose connections.
Follow Expansion Guidelines: When connecting batteries in parallel, use batteries with the same voltage, capacity, model, and state of charge. Follow the manufacturer's recommended wiring configuration for system expansion.
Keep Terminals Clean: Regularly inspect battery terminals and cable connections. Clean any dust, corrosion, or loose connections to ensure efficient power transmission.
Keep Away from Fire and Heat Sources: Do not expose the battery to open flames, sparks, heaters, or other high-temperature sources. Excessive heat may damage the battery and shorten its lifespan.
