12V 17Ah Security System Battery Access Control Battery With Reinforced ABS Casing

The GP17-12 is a high-performance Valve Regulated Lead-Acid (VRLA) battery specifically engineered for high-reliability security applications. With a robust 17Ah capacity and advanced AGM technology, it provides long-lasting and stable power for complex access control networks, multi-door interlocking systems, and high-frequency electronic locking hardware.

Key Specifications

• Model: GP17-12
• Nominal Voltage: 12V
• Nominal Capacity: 17Ah (20HR)
• Design Life: 6 years
• Casing: Reinforced ABS

Why Choose the GP17-12 for High-End Access Control?

• Extended Emergency Runtime:
  Offering 2.4 times the capacity of a standard 7Ah battery, the GP17-12 ensures that in the event of a prolonged power outage in large office buildings or industrial sites, the entire access cabinet—including readers, biometric terminals, and electromagnetic locks—remains operational significantly longer.
• Handles Heavy Load Surges with Ease:
  When a system manages multiple heavy-duty electromagnetic locks (e.g., 280kg or 500kg holding force), the instantaneous current demand is immense. The larger capacity and lower internal resistance of the GP17-12 prevent voltage drops that could otherwise cause the controller to reboot.
• Low Maintenance & High Durability:
  The fully sealed, maintenance-free structure is optimized for the "float charge" environment typical of access control power boxes. The specialized plate alloy minimizes the risk of thermal runaway, even in enclosed, warm equipment rooms.

Typical Application Scenarios

• Multi-Door Controller Cabinets: Provides centralized backup power for 4-door, 8-door, or even 16-door controller setups.
• Heavy-Duty Pedestrian Gates: Ideal for the control circuitry backup of speed gates, turnstiles, and revolving doors.
• High-Security Areas (Vaults/Labs): Meets strict fire and safety regulations requiring critical access points to remain functional for several hours post-power loss.
• Visitor Management Systems: Powers visitor registration kiosks and card dispensers during emergencies.

Expert Advice

• Installation Space: The 17Ah battery is larger than the standard 7Ah model. Always verify that your Power Supply Box or cabinet has sufficient physical dimensions for installation.
• Charging Compatibility: Ensure your power supply's charging output is sufficient for a 17Ah battery. If the charging current is too low (e.g., 500mA), the recharge time after a deep discharge will be significantly longer.
• Quarterly Self-Test: It is recommended to disconnect mains power once every quarter to test the battery's actual performance in triggering all connected electronic locks.
