I. Core Product Parameters

• Rated Parameters: 12V / 24Ah (20HR rate), directly compatible with fire alarm control panels, emergency lighting, and suppression systems without additional voltage regulation.
• Discharge Performance: 20-hour rate ≥24Ah; 10-hour rate ≥22.8Ah; 1-hour rate ≥16.1Ah; supports continuous backup power for 60–120 minutes during power outages.
• Internal Resistance & Self-discharge: Full-charge internal resistance ≤9mΩ, self-discharge ≤3%/month at 25°C, ideal for unattended fire safety applications.
• Charging Parameters: Float charge 13.6–13.8V, equalizing charge 14.4–14.7V, with automatic charge control and overcharge protection.
