QUESTIONS & ANSWERS
The Concorde RG24-15 is a 24-volt, 13.6 Ah valve-regulated lead-acid (VRLA) aircraft battery designed for engine starting and emergency power applications. It is commonly installed in general aviation aircraft to provide dependable starting performance and backup electrical power in the event of generator failure. Its absorbed glass mat (AGM) construction supports reliable operation in demanding aviation environments.
Yes. The Concorde RG24-15 is authorized under FAA Technical Standard Order (TSO) C173a. TSO authorization confirms the battery meets specific FAA performance and quality standards for installation on approved aircraft, supporting regulatory compliance and airworthiness requirements.
Yes. The Concorde RG24-15 24V aircraft lead-acid battery comes standard with a hold-down bar (Concorde part number 9771). This ensures proper installation and secure mounting within the aircraft battery compartment. A correctly secured aircraft battery helps maintain system reliability and airworthiness compliance.
The Concorde RG24-15 aircraft battery delivers 200 cold cranking amps (CCA). This rating supports dependable engine starting performance in a variety of operating conditions. Adequate CCA is critical for the reliable performance of the aircraft's electrical system during startup.
The RG24-15 has a rated capacity of 13.6 amp-hours (Ah) at the C1 rate. This capacity supports both engine starting and emergency electrical loads, helping maintain avionics and essential systems if alternator or generator power is lost.
The RG24-15 is rated at 1025 A peak power (IPP) and 625 A for 15 seconds (IPR) at 23 °C. At -18°C, it provides 600 A IPP and 400 A IPR. These ratings demonstrate strong starting performance in both standard and cold-weather aviation environments.
The RG24-15 has a maximum weight of 29.5 lbs (13.4 kg). This weight is important for aircraft weight-and-balance calculations and helps maintain proper aircraft performance characteristics.
The RG24-15 uses absorbed glass mat (AGM) valve-regulated lead-acid technology with no free electrolyte. This non-spillable design improves vibration resistance and reduces maintenance requirements compared to traditional flooded lead-acid batteries.
Yes. Concorde VRLA batteries, including the RG24-15, are classified as non-spillable and are exempt from DOT and IATA hazardous material regulations when properly packaged. This simplifies shipping and logistics for aircraft operators and maintenance providers.
The recommended charging method is constant potential charging at 28.25V DC ± 0.25V. Proper charging voltage helps optimize battery life, maintain performance, and prevent damage from overcharging or undercharging.
The RG24-15 series has been tested to the RTCA DO-293A and IEC 60952-1 performance standards. Environmental testing includes altitude qualification up to 67,654 feet (20,621 meters). These certifications confirm the battery’s suitability for demanding aviation operating conditions.
For commercial aircraft applications, the RG24-15 is eligible for a full warranty credit if failure due to defects occurs within 180 days (6 months) or 300 hours of operation, whichever comes first. Partial warranty credit may apply beyond that period, depending on installation type and operating time. Proper documentation and compliance with Concorde maintenance procedures are required for warranty claims.
The Concorde RG24-15 is an FAA-approved aircraft battery, while the RG24-15A1 is not approved for aircraft use. The RG24-15A1 is designed for military generator applications and features different terminal configurations. Although the two batteries are similar in overall dimensions, only the RG24-15 is certified for aviation installation and airworthiness requirements.
