The SUNNY 360 Series Central Systems utilizes a fully sealed SUNNY Sealed Lead Acid battery, which typically requires a charging time of approximately 10 to 15 hours. It's best to ensure the battery is fully charged to get the best performance during a power outage. When the power goes out, the emergency light should automatically switch on. It will then start charging when the power is back. If the light only stays on for a brief time during an outage, the battery may not be fully charged, or it might be nearing the end of its life. If this occurs, try a full charge. If the issue continues, consider contacting customer service for a potential battery replacement.
