7639-30LT – Gill Battery 24 Volt LT 100 Amp Extreme Cranking Aircraft Battery for Phenom

Available now on the Airparts.aero Marketplace.

Overview

The Teledyne Gill 7639-30LT is a genuine OEM, high-performance, 24-volt sealed lead-acid battery, engineered specifically as the main ship battery for the Embraer Phenom 100 and 300 series of light and super-light jets. This is not a standard battery; the "LT" designation signifies its Low Temperature capability, providing exceptional starting power and reliability in the most demanding cold-weather operating conditions. Utilizing advanced Valve Regulated Lead Acid (VRLA) and Absorbed Glass Mat (AGM) technology, the 7639-30LT delivers the immense, instantaneous current required for turbine engine starting while serving as a robust source of emergency power.

Key Features

• Enhanced Low-Temperature Performance (LT): Specifically engineered with a low-resistance design and an advanced electrolyte formulation to deliver superior cranking power at extremely low temperatures, ensuring reliable engine starts during cold-soak conditions.
• Superior Turbine Starting Power: Designed to provide the extremely high amperage (rated at 1000+ amps) required to turn the starter-generators of the Phenom's Pratt & Whitney Canada engines, ensuring fast, cool starts that minimize thermal stress on the engine's hot section.
• 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 eliminates the need for water replenishment, making the battery truly maintenance-free.
• Absorbed Glass Mat (AGM): The electrolyte is fully absorbed into a matrix of microfiber glass mat separators. This spill-proof design allows the battery to be mounted in any orientation and renders it completely safe for flight without the risk of acid leakage or corrosion.
• Genuine OEM Specification: As the genuine battery specified by Embraer, it guarantees the correct electrical performance, physical dimensions, and interface with the aircraft's charging and monitoring systems.

The 7639-30LT's "LT" or Low Temperature performance is a result of its optimized internal design. The battery's internal resistance (

Rint​

) is a key factor in its ability to deliver high current; the voltage available to the starter is the battery's open-circuit voltage minus the voltage drop across this internal resistance (

Vdrop​=I×Rint​

). At low temperatures, the electrochemical reaction slows, and the internal resistance of a standard battery increases dramatically, reducing its cranking power. The 7639-30LT uses a specialized electrolyte formulation and thinner, higher-purity lead plates to minimize this increase in resistance, allowing it to deliver a much higher current at cold temperatures than a standard battery of the same size and weight.

Note: This is a flight-critical component. While maintenance-free, regular capacity checks are required as part of the aircraft's maintenance program to ensure continued airworthiness. Always use a temperature-compensating aircraft battery charger/maintainer to ensure maximum battery life. Installation must be performed by a certified A&P or AME mechanic.
