EU Low Voltage Directive FAQ Battery-powered products

A battery-only product below the LVD voltage bands can be outside Directive 2014/35/EU, while its charger, external power supply, or integrated mains supply can still be LVD equipment.

Scope turns on the rated input or output voltage of each electrical item placed on the EU market, not on the fact that the main product uses a battery.

Overview

Battery operation does not answer the LVD question by itself. Apply the 50-1000 V AC and 75-1500 V DC bands to the rated input and output of each electrical item: the battery-powered device, any integrated power supply, any bundled charger, and any separate adapter or external supply.

Question 1

When is the battery-powered device itself in LVD scope?

Directive 2014/35/EU applies to electrical equipment designed for use with a voltage rating between 50 and 1000 V AC or between 75 and 1500 V DC, unless an exclusion applies. The Commission LVD guide explains that the relevant rating is the rated electrical input or output, not every voltage that may appear inside the equipment.

A battery-operated device whose supply rating is below 50 V AC and below 75 V DC is outside the LVD voltage range when assessed on its own. If the same finished product has an integrated mains supply, or another rated input or output inside the LVD bands, assess that finished configuration under the LVD.

  • Check the product as placed on the EU market, including its declared ratings, supplied configuration, instructions, and labels.
  • For multiple input or output ratings, the Commission guide treats the product as in scope as soon as the highest rating falls within the LVD voltage bands.
  • Internal generated voltages do not by themselves bring an otherwise extra-low-voltage battery device into Article 1 scope, but they can still be relevant to risk analysis when the equipment is otherwise in scope.
  • Equipment designed for more than 1000 V AC or more than 1500 V DC is outside the LVD voltage range, even though other safety rules may still apply.

Commission guidance explains that battery-operated equipment outside the voltage rating is outside the LVD, while the rated input or output remains the key scope test.

Recommended next step

Separate the battery device from the supply equipment

Check the rated input and output of the device, charger, adapter, external supply, and integrated supply before deciding the LVD route.

Question 2

How should chargers, adapters, and external supplies be routed?

The charger or external power supply should be assessed as its own electrical equipment. The Commission guide states that an accompanying battery charger, and equipment with an integrated power supply unit within the LVD voltage ranges, are in the scope of the LVD.

This means a single consumer bundle can contain two different scope answers: the battery device may be outside the LVD voltage band, while the mains charger, USB power adapter, dock, or detachable external supply is inside the LVD because of its own rated input or output.

  • Keep separate scope notes for the device, charger, adapter, dock, and external supply when they have separate ratings, labels, suppliers, or declarations.
  • If the charger or adapter is placed on the market separately, keep its own LVD technical documentation, EU declaration of conformity, CE marking evidence, and instructions.
  • If the charger is bundled only with the product, still keep evidence showing how the main product manufacturer verified that the supplied electrical items satisfy the LVD requirements that apply to them.
  • For battery chargers, check whether a harmonised standard listed for LVD, such as EN 60335-2-29 where relevant to the product, is used and whether any limitations or updates affect the claim of presumption of conformity.

Question 3

Which hazards and file evidence matter for in-scope equipment?

For equipment that is in LVD scope, the safety assessment is not limited to electric shock. The Commission guide describes the LVD as covering all safety aspects of electrical equipment, including non-electrical hazards arising from that equipment.

The technical documentation should connect the scope answer to the actual hazards of the battery product or supply configuration: rated supply, insulation, overheating, overload, mechanical protection, environmental influences, instructions, warnings, standards used, examinations, and test reports.

  • Record the exact marketed configuration: bare battery device, integrated supply, supplied charger, adapter, cable, dock, spare part, or replacement supply.
  • Keep an adequate risk analysis and assessment, including foreseeable use and foreseeable overload conditions relevant to the electrical equipment.
  • List harmonised standards applied in full or in part, and identify the technical solution used for safety objectives not covered by those standards.
  • Store design drawings or schemes, explanations, calculations, examinations, test reports, labels, instructions, production controls, and declaration evidence together.

Question 4

How do EMC, RED, and Batteries overlap with the LVD file?

Use the LVD file to route safety obligations for electrical equipment within the LVD voltage bands. Use separate routing for other Union acts that apply to the same marketed product or bundle, and make the EU declaration identify the applicable Union acts when more than one declaration regime applies.

For radio products, the LVD guide says radio equipment within the RED scope is not subject to the LVD, while RED Article 3(1) refers to safety requirements identical to the LVD and to EMC essential requirements. For non-radio electrical equipment, EMC can still apply to electromagnetic disturbance while the LVD covers safety aspects, including electromagnetic aspects where they relate to safety.

  • Radio-enabled battery product: route radio equipment through RED for the radio product, then separately assess any supplied charger or external power supply that is not itself radio equipment.
  • Non-radio battery product with electronic circuits: keep EMC evidence separate from LVD safety evidence, and do not treat an EMC test report as proof of LVD safety.
  • Battery or waste-battery obligations: the cited LVD sources identify Regulation (EU) 2023/1542 as a separate product law, but do not provide enough detail here to state battery-regulation duties on this FAQ page.
  • Declaration routing: when the electrical equipment is subject to more than one Union act requiring an EU declaration, the LVD allows a single EU declaration covering those Union acts and publication references.

Question 5

What should the scope note say?

The useful record is a short product-specific scope note, not a generic statement that the product is battery powered. It should identify every electrical item in the marketed configuration and give a separate conclusion for each item.

For each item, record the rated input and output, whether the LVD voltage band is met, whether Annex II or RED changes the route, which standards or technical specifications are used, and where the declaration and test evidence sit.

  • Device conclusion: outside LVD voltage band, inside LVD voltage band, excluded, or routed through RED or another product regime.
  • Supply conclusion: integrated power supply, external supply, charger, adapter, dock, and cable conclusions with ratings and evidence references.
  • Hazard conclusion: foreseeable electrical and non-electrical hazards considered for any in-scope equipment.
  • File routing: technical documentation, EU declaration, CE marking artwork, instructions, supplier controls, and review trigger for rating, charger, supplier, radio module, or standards changes.
