Built-In Protection Functions This Photonic Universe battery charger incorporates multiple safety features for reliable and unattended operation. These include protection against DC short circuit • overheating • overcharging • and reverse polarity of the battery. The charging voltage is also free from peaks, ensuring smooth and uninterrupted charging. Common Questions What types of batteries can this charger be used with? This charger is compatible with 12V Lead Acid batteries, including AGM, Gel, and Wet cell types. It is crucial to select the correct battery type setting on the charger for optimal performance. Can I leave the charger connected to my battery indefinitely? Yes, the 7-stage automatic charging process includes a float stage that maintains the battery at 100% charge without overcharging, making it safe for long-term connection. What is the 'Power Pack Function'? The Power Pack Function allows the charger to supply a direct 12V DC output to power compatible loads, such as a 12V fridge, even when no battery is connected. This is useful for temporary power needs or during battery replacement. How does the charger handle older or deeply discharged batteries? The charger features a 'Boost-charging' stage to improve the condition and recover lost capacity from older batteries, and a 'Desulphation' stage to break down sulphation in deeply discharged batteries, helping to restore them to full charge. Installation Notes Ensure the charger is placed in a well-ventilated area to prevent overheating. Connect the charger to the battery terminals with correct polarity (+ to + and - to -) before plugging into the mains. Refer to the user manual for detailed wiring instructions and operational guidance. Ensure all connections are secure to prevent arcing or poor performance.
