Hager 2-679-0661 5 Amp-Hour Battery Backup for 2908 & 2909 Power Supplies

The Hager 2-679-0661 is a sealed, maintenance-free 5 Amp-hour (Ah) rechargeable battery backup module engineered specifically for the Hager 2908 and Hager 2909 regulated power supplies. When primary 120VAC input is interrupted, this battery pack sustains power to electric strikes, magnetic locks (maglocks), and electric exit devices — keeping controlled openings secure and code-compliant through any power outage. It is a purpose-built drop-in accessory for the Hager 2900-series power supply platform, charging automatically from the host supply and returning to standby the moment line power is restored.

Key Features & Benefits

• 5 Amp-Hour Standby Capacity: Sealed lead-acid battery sized to sustain electric door hardware loads during a loss of primary power, providing extended backup runtime for typical access-control loads.
• Direct 2908 / 2909 Compatibility: Purpose-designed accessory for the Hager 2908 (1 Amp output) and 2909 regulated power supplies — no adapters or modifications required.
• Automatic Recharge: Charges continuously from the host power supply; returns to full standby automatically when line power is restored, requiring no manual intervention.
• Maintenance-Free Construction: Sealed, spill-proof design requires no watering, venting, or periodic servicing over its full service life.
• Access-Control & Life-Safety Ready: Keeps electric strikes, maglocks, and electrified exit hardware energized during outages so openings remain under access control and egress-compliant.
• Drop-In Installation: Designed to install inside or alongside the Hager 2900-series power supply enclosure with no additional wiring infrastructure needed.

Applications

The 2-679-0661 is well suited for healthcare facilities, K–12 and higher-education campuses, government buildings, and commercial offices where electric-lock openings must remain operable during a power failure. It is particularly appropriate in life-safety and emergency-egress installations governed by NFPA 101 or local fire codes that require continued locking-hardware operation during an outage.
