How Do Portable Battery Rules Apply Inside Appliances?

Portable batteries in appliances are batteries incorporated into products, from phones and laptops to power tools, toys and household devices, where the battery and the appliance form a single product as placed on the market. Regulation (EU) 2023/1542 sets removability, replaceability, labelling and information duties for incorporated portable batteries, with the aim that the battery can be removed and replaced by the end user throughout the lifetime of the product, subject to the derogations in Article 11. The appliance and the battery must be considered together, but the battery duties must not be lost inside the appliance file.

The incorporated battery question is a design question before it is a record question. An appliance designed with a battery that cannot be removed without damage, special tools or professional training fails the removability purpose, even when the appliance itself is well designed. Design, instructions and spare battery availability must be planned together, because a removable design without instructions or spare availability still leaves the holder unable to replace the battery in practice.

What does removability require for incorporated batteries?

Removability requires that a portable battery incorporated in a product can be readily removed and replaced by the end user, using commercially available tools where tools are needed, without damage to the battery or the product, throughout the lifetime of the product. The Commission guidance on removability and replaceability clarifies that removability is possible when the battery can be safely taken out by the end user, with or without tools, avoiding damage, and replaceability means the battery can be replaced with another battery without damage or loss of function. The end user in the guidance is a person of majority age without specific experience or qualifications for battery removal.

A design check should test removal on the finished product, with an end user profile tester, using only the tools and instructions supplied. A design that passes a workshop test with specialist tools and training does not pass the end user test. The test should cover removal, replacement, reconnection and safe handling, and the result should be recorded with the product model, the tester profile and the tools used. A design change that affects removal, such as a new adhesive or fastening, needs a fresh test.

What derogations apply to removability?

Derogations from end user removability apply where the Regulation provides them, including products where continuous power supply is needed for safety or data integrity, products where removal by the end user would compromise safety, and product categories added by delegated act where professional replacement is required to ensure user and appliance safety. The delegated act adopted in July 2026, identified as C(2026) 5031 in secondary reporting, added specified product categories to the professional replacement framework, subject to conditions. Each derogation is narrow, conditional and product specific, and it does not create a general exemption for a product class.

Worked check: a wearable device is claimed to fall under a professional replacement derogation. The check asks for the derogation provision relied on, the safety need, and the delegated act category where relevant. A claim that states only that the device is small or sealed, without a derogation provision, fails the check. A claim that cites the provision and shows the safety need, with professional replacement availability, passes the first stage of the check.

How must replacement batteries be available?

Replacement batteries for incorporated portable batteries must be available to end users, and the product must be designed to accept original and compatible batteries without compromising safety or performance, as clarified in the Commission guidance. Availability means that a holder can obtain a replacement battery through a stated route, at the time the battery needs replacement, without being required to return the whole product for a battery change that the holder could carry out. A design that allows removal but provides no replacement route leaves the holder with a removable battery that cannot be replaced in practice.

Availability should be checked as a holder journey: from the point of battery failure, through the replacement search, to fitting. A journey that ends at a spare part page with stock, price and fitting instructions passes the first stage. A journey that ends at a service centre booking for a battery change that the holder could carry out, with no spare part route, fails the availability purpose. The journey test should be repeated when the product model or the spare part route changes.

What information must accompany an incorporated battery?

Information for an incorporated portable battery includes the battery type, chemistry, capacity where required, safety and handling instructions, removability and replacement instructions, and separate collection information, presented in the product instructions and, where required, on the battery or packaging. The information must be available to the end user throughout the product lifetime, not only at first sale, and it must match the battery model actually incorporated. A product that ships with a different battery variant from the variant described in the instructions carries a mismatch that affects removal, safety and replacement.

Information checks should compare the instructions, the battery label, the packaging and the spare part information for the same product model and battery variant. A difference in chemistry, capacity or removal method between any two sources should be treated as a record error. The check should be carried out for each variant, because a variant change in battery supplier or format can change the instructions, even when the appliance model name stays the same.

How do appliance rules and battery rules interact?

Appliance rules and battery rules interact where a product specific law sets a different removability or durability route, as with mobile phones under ecodesign rules that provide an alternative professional repair route subject to durability conditions. In such cases, the product specific law takes precedence on the point it covers, as clarified in Commission guidance, while the battery rules continue to apply on the points they cover. A product team must therefore read both laws together, identify the precedence point, and record which law governs each design decision, rather than applying one law alone to the whole product.

The interaction record should list each design decision, the law relied on, and the precedence basis where two laws overlap. A record that cites only the battery Regulation for a phone battery decision, without addressing the ecodesign route, is incomplete. A record that cites only the ecodesign route, without addressing the battery labelling and collection duties, is also incomplete. The two laws together define the product duties, and the record should show both.

What evidence supports an incorporated battery file?

An incorporated battery file should contain the classification note, the removability test, the derogation analysis where relied on, the replacement availability evidence, the information set, and the labelling presentation. The file should be kept with the appliance technical documentation and available to a market surveillance authority on request. As checked on 28 October 2026, removability guidance and delegated act categories should be checked for the current position before a design is finalised.

A reader with a specific battery or market decision should check the current Regulation text and any applicable delegated act, as checked on 28 October 2026, before acting.
