Description

Kongsberg 319554 | cNODE Maxi Battery Pack Core Category

Dynamic Product Introduction

Deploying subsea acoustic transponders in deep-water environments demands an uncompromising power source capable of sustaining long deployment cycles under extreme hydrostatic pressure. The Kongsberg 319554 (Type D48-Li) battery pack eliminates the risk of premature subsea power failure, providing stable, long-duration energy specifically engineered for cNODE Maxi transponders.

Surpassing standard commercial battery configurations through specialized chemical sealing and robust internal fusing, this power pack protects valuable offshore assets against leakage and voltage dropouts. Field operators rely on its drop-in mechanical alignment and verified energy density to maximize deployment windows and reduce costly offshore vessel time for routine maintenance.

Key Technical Specifications

Global Sourcing & Live-Test SOP (Transparency Core)

Procuring primary lithium power packs for critical subsea infrastructure requires absolute compliance with safety, freshness, and traceability standards:

• Inbound Verification: Every battery batch is audited via factory date codes, UN 38.3 test summary documentation, and anti-counterfeit packaging seals to verify fresh manufacturing provenance.
• Live Simulation: Sample cells from production lots undergo open-circuit voltage (OCV) testing and closed-circuit voltage response verification under simulated load conditions.
• Diagnostics: Impedance checks and multi-meter isolation tests confirm zero internal short circuits or self-discharge anomalies before the units are cleared for dispatch.
• Final Prep: Terminals are protected with heavy-duty insulating caps, and units are sealed in heavy-gauge moisture-barrier packaging compliant with dangerous goods shipping regulations.

The Field Engineer’s Pitfall Guide

❗ Voltage Delay and Passivation Layers: Storing lithium packs in ambient conditions for extended periods can build a microscopic passivation film on the lithium anode, causing a temporary voltage drop upon initial high-current pulse loading. (I’ve seen offshore crews panic during pre-deployment checks when an unconditioned pack briefly sagged under load before breaking through its passivation layer.)

❗ Mishandling Subsea O-Rings: Failing to clean and lightly lubricate the transponder end-cap sealing surfaces during battery replacement can cause catastrophic water ingress under deep deployment pressure.

❗ Expired Shelf-Life Deployment: Installing legacy surplus batteries past their recommended service window risks severe capacity exhaustion mid-campaign, losing critical acoustic positioning links.

Intent-Driven FAQ

Can the Kongsberg 319554 battery pack be recharged after depletion?

No, this is a primary non-rechargeable lithium metal battery pack; attempting to recharge it creates a severe fire and explosion hazard.

What specific transponder models are compatible with part number 319554?

This specific pack is engineered exclusively for Kongsberg cNODE Maxi acoustic transponders (including ACS500 series hardware variants).

How should spent battery packs be handled for disposal or shipping?

Spent packs must be handled in strict accordance with local environmental regulations and UN dangerous goods shipping laws governing lithium metal batteries.

Are these units supplied factory-fresh with valid UN 38.3 documentation?

Yes, every battery shipment includes the mandatory safety test summaries and compliance documentation required for international freight forwarding.
