S1840510-01 - Textron Aviation ELT Battery Replacement for BAT200

S1840510-01 – Textron Aviation ELT Battery Replacement Kit (replaces Kannad BAT200)

Available now on the Airparts.aero Marketplace.

The Textron Aviation S1840510-01 is the genuine OEM, flight-critical, life-limited battery replacement kit for the Kannad 406 AF-COMPACT Emergency Locator Transmitter (ELT). This is the TSO-certified, factory-authorized power source designed to ensure the proper function of this life-saving device. Its sole purpose is to provide the necessary power for the ELT to transmit a powerful 406 MHz distress signal to the Cospas-Sarsat satellite network, along with a 121.5 MHz homing signal, in the event of an aircraft accident.

This battery pack utilizes a long-life Lithium Manganese Dioxide (LiMnO2​) chemistry, specifically chosen for its high energy density, excellent performance in extreme cold, and exceptionally low self-discharge rate. As a mandatory life-limited component, this battery must be replaced on or before the expiration date marked on the unit to ensure the ELT will perform as certified during an emergency. The airworthiness of the aircraft and the lives of its occupants depend on the guaranteed performance of a genuine, in-date battery.

Key Features

• Genuine Textron Aviation Certified Part: The only battery pack certified for use in the Kannad 406 AF-COMPACT ELT on specified Textron airframes.

• Long-Life Lithium Manganese Dioxide (LiMnO2​) Chemistry: Provides a high energy density and a 5-year replacement life, ensuring the battery is ready after years of dormancy.

• Mandatory Replacement Life: Clearly marked with a Date of Manufacture and a replacement-due date that must be strictly observed to maintain airworthiness.

• TSO-C126 Compliant: Manufactured to meet the rigorous performance standards of FAA TSO-C126, which requires reliable operation for at least 24 hours at -20°C.

• Hermetically Sealed Cells for Safety: Each lithium cell is hermetically sealed in a steel casing to prevent leakage and ensure safety under all operating conditions.

• Includes All Required Components: The kit typically includes the battery pack, a new O-ring seal, and required placards for a complete and compliant replacement.

Aircraft Compatibility

The S1840510-01 battery kit is the specified replacement for the Kannad 406 AF-COMPACT ELT commonly installed as factory equipment on many modern Textron Aviation (Cessna) aircraft. Common models include, but are not limited to:

• Cessna 172S Skyhawk

• Cessna 182T, T182T Skylane

• Cessna 206H, T206H Stationair

Crucial Note: Verification against the specific aircraft's Illustrated Parts Catalog (IPC) and equipment list is mandatory to ensure correct part number applicability.

Applications

• Sole power source for the Kannad 406 AF-COMPACT Emergency Locator Transmitter.

• Mandatory replacement during scheduled aircraft maintenance when the battery expiration date is reached.

Why Choose S1840510-01?

An Emergency Locator Transmitter is a piece of equipment you hope to never use, but if you do, your life will depend on it. Choosing the genuine S1840510-01 battery is a non-negotiable requirement for flight safety and regulatory compliance. Using a non-certified, expired, or unauthorized "re-celled" battery pack voids the ELT's TSO approval, renders the aircraft unairworthy, and creates an unacceptable risk that the beacon will fail to transmit when needed most. The genuine OEM battery is the only way to guarantee that the ELT will have the power to perform its life-saving function as certified by the FAA and the manufacturer.

The electrochemistry of the Lithium Manganese Dioxide (LiMnO2​) primary cells used in the S1840510-01 battery pack is specifically selected for the unique demands of an ELT. This cell chemistry is prized for its combination of high cell voltage (~3.0 V), high energy density, and an exceptionally low self-discharge rate (typically <1% per year), which is critical for a device that must remain dormant for years yet function perfectly on demand. The cell consists of a high-purity lithium metal anode (the negative electrode) and a solid cathode of heat-treated electrolytic manganese dioxide. These are separated by a microporous polymer membrane saturated with a non-aqueous organic electrolyte, typically a solution of a lithium salt (like lithium perchlorate) in a mixture of organic solvents (like propylene carbonate and dimethoxyethane). The absence of water in this electrolyte is the key to the battery's extremely long shelf life and its excellent performance at the sub-zero temperatures mandated by TSO-C126, an environment where aqueous electrolytes would freeze and cease to function.

Note: This is a flight-critical, life-limited safety component. It MUST be replaced on or before the expiration date marked on the battery. Federal Aviation Regulations (e.g., 14 CFR § 91.207) mandate the replacement of ELT batteries to maintain aircraft airworthiness. Installation must be performed by a certified A&P or avionics technician. After installation, an operational test of the ELT must be performed and logged in the aircraft's records in accordance with the manufacturer's instructions and FAA regulations.

Documentation

The definitive installation, testing, and replacement procedures are detailed in the Component Maintenance Manual for the Kannad 406 AF-COMPACT ELT. Applicability must be confirmed via the aircraft's parts catalog.
