SR02493LA – Teledyne Gill Battery STC Kit for Airbus Helicopters and 7641-20 Batteries
Available now on the Airparts.aero Marketplace.
Overview
The Teledyne Gill SR02493LA is a complete, FAA-approved Supplemental Type Certificate (STC) kit that authorizes the installation of two high-performance Gill 7641-20 sealed lead-acid batteries into various Airbus Helicopters AS350 and AS355 models. This comprehensive kit provides not only the legal documentation but also all the necessary, precision-engineered hardware to perform this critical upgrade. By replacing older, maintenance-intensive battery technologies (like flooded lead-acid or Ni-Cad) with Gill's modern, sealed VRLA/AGM batteries, this STC offers a significant enhancement in aircraft performance, reliability, and safety.
Key Features
- Complete, Certified Modification Package: This is not just a single part, but a complete, engineered kit containing the STC documentation, installation drawings, and all required hardware to legally and safely modify the aircraft.
- Enables Modern Battery Technology: Facilitates the upgrade to two Gill 7641-20 Valve-Regulated Lead-Acid (VRLA) / Absorbed Glass Mat (AGM) batteries. This provides higher cranking power, zero maintenance (no watering), and non-spillable safety.
- Custom-Engineered Battery Tray: The kit includes a custom-fabricated battery box or tray, designed with the precise dimensions and mounting points to securely hold the 7641-20 batteries in the airframe, replacing the original battery box.
- Simplified Installation: Provides all necessary brackets, fasteners, and wiring harnesses/jumpers to ensure a straightforward, "bolt-on" installation with minimal modification to the existing airframe structure.
- Enhanced Aircraft Value & Utility: Upgrading to a modern, reliable, and maintenance-free sealed battery system is a significant operational upgrade that increases dispatch reliability and enhances the overall value of the helicopter.

Applications
The SR02493LA STC kit is the all-in-one solution for a major aircraft system upgrade:
- Battery System Modernization: The primary application is to upgrade from older, maintenance-intensive batteries to modern, high-performance sealed batteries.
- Improving Starting Performance: The high cranking power of the 7641-20 batteries provides faster, cooler starts for the turbine engine, reducing wear on the starter-generator.
- Enhancing Safety: Eliminates the risk of hazardous acid spills from flooded batteries and provides a more robust and reliable source of emergency power.
Why Choose STC Kit SR02493LA?
Changing the type of battery in a certified aircraft is a major modification that affects weight & balance, electrical load analysis, and airworthiness. The Teledyne Gill SR02493LA STC kit is the only legal and safe way to perform this upgrade. It provides all the pre-approved engineering data, certified hardware, and FAA authorization needed for the modification. Attempting this change without an STC would be a significant violation of aviation regulations and would render the aircraft unairworthy. This kit is a complete, turnkey solution from the battery experts.

A Supplemental Type Certificate (STC) is an FAA approval for a major modification to an existing type-certified aircraft. The SR02493LA kit represents thousands of hours of engineering and testing by Teledyne Gill to prove to the FAA that the installation of their 7641-20 batteries is safe and meets all applicable airworthiness regulations. This includes structural analysis of the new battery tray and its attachment to the airframe, electrical load analysis to ensure the aircraft's charging system is compatible with the AGM batteries, and development of an Approved Flight Manual Supplement (AFMS) that provides the pilot with the necessary operating procedures and limitations for the new system. The purchase of the kit grants the operator the right to use this pre-approved data to legally perform the modification on their specific aircraft.
Note: This is a major modification and must be performed and documented by a certified A&P mechanic with Inspection Authorization (IA) or at a Part 145 repair station, in strict accordance with the STC's installation instructions. An FAA Form 337 must be completed and filed upon completion of the modification.
