GMDSS ACR LITHIUM SURVIVAL BATTERY PRODUC NO. 1066 USA 17:08

The ACR Lithium Survival Battery (P/N 1066) is a professional-grade, high-capacity lithium iron disulfide (Li/FeS₂) battery pack designed specifically for GMDSS (Global Maritime Distress and Safety System) emergency equipment. Its sole purpose is to provide a long-lasting, ultra-reliable, and temperature-resistant power source for Emergency Position Indicating Radio Beacons (EPIRBs) and Search and Rescue Transponders (SARTs).

This is not a standard consumer battery; it is a critical, certified component of a vessel’s lifesaving apparatus.

Key Features & Specifications

• Manufacturer: ACR Electronics, Inc. (A world-leading brand in marine safety and survival equipment, now part of ACR Group, LLC. Their products are renowned and often mandated in the maritime industry).

• Type: Lithium Iron Disulfide (Li/FeS₂). This chemistry was chosen for survival equipment because it offers:

  • Exceptional Shelf Life: Typically 10 years from the date of manufacture. It has an extremely low self-discharge rate.

  • Superior Cold Weather Performance: Operates effectively in extreme temperatures (often rated from -40°C to +60°C / -40°F to +140°F), which is crucial for survival situations at sea.

  • High Energy Density: Provides a lot of power in a compact, lightweight package.

  • Reliability: Less voltage sag under load compared to alkaline batteries, ensuring the beacon transmits at full power for its entire rated duration.

• Voltage: ~6.0 Volts (a stable voltage suitable for the electronics in EPIRBs and SARTs).

• Capacity: High amp-hour (Ah) rating designed to power an EPIRB for a minimum of 48 hours of continuous transmission (meeting and exceeding international standards).

• Compliance: This battery is certified to meet strict international regulations, including:

  • GMDSS Requirements

  • SOLAS (Safety of Life at Sea) Convention

  • IMO (International Maritime Organization) Performance Standards

  • ETSI (European Telecommunications Standards Institute)

  • FCC (Federal Communications Commission)

• Date of Manufacture: Critically, every survival battery has a manufacture date and an expiration date (usually 10 years later). It is illegal and extremely dangerous to use an expired battery in a safety device. The date is printed on the battery pack itself.

• Physical Design: Engineered as a direct replacement pack for specific ACR EPIRB and SART models. It is a sealed unit with a specific connector to ensure it cannot be installed incorrectly.

Purpose and Critical Importance

This battery is the “heart” of an EPIRB or SART. When a vessel is in distress, the crew activates the EPIRB, which uses the power from this battery to send a powerful distress signal via satellite to search and rescue authorities worldwide. The reliability of this battery is literally a matter of life and death.

Who is this for? (Ideal User)

This is a replacement battery for:

• Commercial vessel operators (cargo ships, tankers, passenger ferries) who are legally required under SOLAS/GMDSS to carry certified EPIRBs with in-date batteries.

• Professional fishermen operating offshore.

• Serious offshore recreational sailors and yacht owners who prioritize safety and compliance.

• Marine safety officers and ship chandlers who stock spare parts for safety equipment.
