G-6381E – Gill Battery Dry Charged 24 Volt Aircraft Battery

Available now on the Airparts.aero Marketplace.

Overview

The Teledyne Gill G-6381E is a high-capacity, 24-volt, dry-charged, valve-regulated lead-acid (VRLA) aircraft battery, engineered specifically for the extreme power demands of turbine engine starting and essential power for business jets. This is a flight-critical component designed for high-performance aircraft like the Gulfstream GIII/GIV and Bombardier Challenger 600 series. The G-6381E is shipped "dry charged"—without electrolyte—a key feature that provides an indefinite shelf life. Once activated by a certified technician, it delivers the immense current required for APU and main engine starting while serving as a reliable source of emergency power.

Key Features

• Dry Charged for Indefinite Storage: The battery is manufactured with fully charged plates and shipped without electrolyte. This allows the battery to be stored for an indefinite period without degradation or the need for periodic charging. It is activated only when needed by adding the specified electrolyte.
  
• Superior Turbine Starting Power: Engineered with a low-impedance design, featuring heavy-duty, through-the-partition intercell connections. This provides a higher voltage under load and delivers the massive, instantaneous amperage required to spool up large turbine engines.
• Valve Regulated Lead Acid (VRLA) Technology: Features a pressure-controlled valve system that regulates the recombination of internal gases (oxygen and hydrogen) back into water. This recombinant gas process significantly reduces water loss compared to older flooded batteries.
• Robust Construction: Built to withstand the harsh G-forces and vibration of the flight environment. The heavy-duty internal construction ensures maximum durability and reliability for transport-category aircraft.
• Genuine OEM Specification: As a genuine Teledyne Gill battery, it is manufactured to the original specifications required by the aircraft manufacturer, ensuring proper fit, electrical performance, and airworthiness.

Aircraft Compatibility

The G-6381E is the specified OEM battery for some of the world's most successful and long-running large-cabin business jets. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification.

• Primary Aircraft Models:
  • Gulfstream: GIII, GIV, G300, G400
  • Bombardier: Challenger 600, 601
  • Dassault Falcon: 20, 200

Applications

The G-6381E is the primary electrical storage and emergency power source on these aircraft:

• APU & Main Engine Starting: Provides the extremely high-amperage current required to turn the starter-generators for both the Auxiliary Power Unit (APU) and the main turbofan engines.
• Emergency Power: In the event of a total generator failure, it provides DC power to the aircraft's essential and emergency busses, powering critical flight instruments, avionics, and lighting.
• Ground Operations: Powers aircraft systems on the ground when a GPU is not available.

Why Choose G-6381E?

For MROs and flight departments, the G-6381E's dry-charged delivery offers a significant logistical advantage, allowing a certified replacement battery to be stocked for long periods without maintenance. Once activated, it provides the legendary reliability and immense starting power that Teledyne Gill is known for. Using a genuine, OEM-specified battery is the only way to ensure the aircraft has the certified power reserves and starting capability required by the manufacturer for all operational and emergency scenarios.

The "dry charged" state of the G-6381E is a specific manufacturing process. The battery plates are fully formed and charged at the factory. They are then washed and dried using a special process, and the battery is assembled and sealed in a dry state. In this condition, no electrochemical reaction can occur, which gives the battery its indefinite shelf life. The activation process involves carefully filling each cell with the specified sulfuric acid electrolyte (e.g., MIL-SPEC-A-825, Type II, Class I). Once filled, the battery is "hot" and ready for a topping charge and capacity check before being placed into service. This process ensures a fresh, full-capacity battery is installed every time, regardless of how long it was stored.

Note: This is a flight-critical component that is shipped dry and without hazardous material classification. Activation (filling with electrolyte) and initial charging MUST be performed by a certified A&P mechanic or at a qualified Part 145 repair station in strict accordance with the Teledyne Gill maintenance manual for this battery model. Failure to follow the correct activation procedure can result in reduced battery capacity, shortened service life, or permanent damage.
