1. Introduction

Emergency beacons, including EPIRBs (Emergency Position Indicating Radio Beacons) and PLBs (Personal Locator Beacons),
are critical life-saving devices used in maritime, aviation, and outdoor survival scenarios. These devices rely on
highly reliable lithium batteries to provide uninterrupted operation during emergencies, often in extreme conditions.

PKNERGY, with 26 years of experience in custom lithium battery manufacturing, offers tailored OEM and ODM solutions
that ensure maximum safety, longevity, and global compliance. Our batteries support clients across Europe, the US,
and Asia, enabling life-saving devices to function reliably wherever they are deployed.

2. Application Background

Emergency beacons have stringent technical and operational requirements:

• Extended Shelf Life: Batteries may remain unused for years and must retain sufficient charge for immediate activation.
• Extreme Environment Durability: Devices are exposed to saltwater, rain, shock, and temperature fluctuations.
• Size and Weight Constraints: Compact, lightweight batteries enable portability and ease of installation.
• Regulatory Compliance: Compliance with IEC62133, UL, UN38.3, and CE is mandatory for international deployment.
• Reliable Output: Instant full-power output is required for distress signaling, ensuring devices function without fail.

These factors necessitate a meticulously engineered battery solution that balances capacity, safety, and operational reliability.
