ADR 1.3 (2025): Safe storage and transport of lithium batteries – What you absolutely need to know

Introduction

Since January 2025, the ADR regulations have been updated, strengthening training requirements for anyone handling, storing, or transporting lithium batteries. These batteries are classified as dangerous goods, and improper handling can pose serious risks to people and infrastructure.

In this article, we share everything you need to know to comply with ADR 1.3 and ensure the safe storage and transport of lithium batteries.

What is ADR 1.3?

Chapter 1.3 of ADR 2025 requires mandatory training for all personnel involved in the transport of dangerous goods. This includes:

  • Shippers
  • Package preparers
  • Handlers
  • Logistics managers
  • Drivers not covered under ADR 8.2
  • Any personnel in direct contact with lithium batteries

Objective of ADR 1.3 Training

The training enables personnel to:

  • Understand regulatory requirements (1.3.2.1)
  • Correctly apply procedures related to their role (1.3.2.2)
  • Identify risks and act in case of an incident (1.3.2.3)

👉 Training is mandatory before taking up an autonomous position and must be refreshed regularly.

Risks Related to Lithium Batteries

Lithium batteries present a risk of thermal runaway: an uncontrolled chain reaction that can cause fire, explosion, or release of toxic gases.

Main causes include:

  • Overheating or overcharging
  • Mechanical shock
  • Manufacturing defects
  • Short-circuit

Strict storage and transport protocols are essential.

Safe Storage of Lithium Batteries

Regulations and Distinctions

  • Active storage: batteries charging or connected
  • Passive storage: batteries at rest

Storage areas must meet strict safety standards.

Best Practices

  • Stable temperature (15–25 °C)
  • Ventilated area, isolated from flammable materials
  • Fire/gas detection systems
  • Batteries separated and protected against shocks
  • Clear emergency procedures (appropriate extinguishers, power cut-offs…)

Transport of Lithium Batteries According to ADR

Classification

  • UN3480: lithium-ion batteries alone
  • UN3481: lithium-ion batteries contained in or with equipment
  • UN3090 / UN3091: lithium metal batteries

Key Obligations for Carriers

  • Use UN-approved packaging
  • Proper labeling (pictograms, UN code, hazard statement)
  • Check for limited quantity exemptions
  • Maintain administrative documentation including SDS and ADR documents

Focus on ADR 1.3 and Non-Driver Personnel

Even logistics operators who pack or prepare shipments are subject to ADR 1.3: they must understand responsibilities, safety instructions, emergency actions, and required documentation.

Summary of ADR 1.3 Training Content (ADR 2025)

Training Type Content / Objective
1. General Awareness Understand general ADR regulations on the transport of dangerous goods.
2. Specific Training Training tailored to job functions (packing, labeling, document prep, handling, etc.), including multimodal requirements.
3. Safety Training Identify risks and hazards related to dangerous goods (fire, explosion, leakage) and know emergency procedures.
4. Periodic Refresher Update knowledge at regular intervals, especially when regulations change.
5. Documentation Employer must maintain proof of training, available on request to authorities or during job changes.

📋 Operational Checklist (Storage + Transport)

Storage

  • Ventilated area, temperature-controlled
  • Fire detection
  • Batteries isolated, no overcharging
  • Emergency procedures known
  • Safety Data Sheets accessible

Transport

  • Verified UN code
  • Approved packaging
  • ADR-compliant labeling
  • Shipping documents and SDS included
  • Personnel trained under ADR 1.3 (with up-to-date proof)

Is ADR 1.3 Training Required in 2025?

Yes. Since the ADR update, all personnel exposed to lithium battery risks must provide proof of training. Lack of training can result in:

  • Administrative sanctions (inspections by DREAL or customs)
  • Company liability in case of accidents

Conclusion: Mastering ADR 1.3 to Secure Your Logistics

Lithium batteries are not just products—they are dangerous goods regulated by strict legislation.

ADR 1.3 (2025 version) requires upskilling of all personnel involved. Far from a constraint, this ensures safety, compliance, and protects your professional reputation.
