The removable battery rule: what changes for product design from February 2027
From 18 February 2027, portable batteries in consumer products must be removable and replaceable by the end user under Article 11. What that means mechanically, which product categories are affected, why the wet-environment exemptions are narrower than sellers assume, and how the transition treats stock already on the market.
From 18 February 2027, a portable battery inside a product sold in the EU has to come out. Article 11 of Regulation (EU) 2023/1542 requires portable batteries incorporated into appliances to be readily removable and replaceable by the end user, and products that fail that test cannot be placed on the EU market.
This is not a filing requirement. It is a design and sourcing constraint, and the products being specified now for 2027 inventory are the ones affected.
What Article 11 actually says
Two obligations, aimed at different battery types.
Portable batteries in appliances must be readily removable and replaceable by the end user. "Readily removable" means the battery can be removed with commercially available tools, without needing specialised tools — unless those are provided free with the product — and without needing proprietary tools, thermal energy or solvents to disassemble the unit. Manufacturers must supply instructions and safety information about removal and replacement, and make them available for the expected lifetime of the product, including online in a permanently accessible form.
LMT batteries, and batteries in light means of transport, plus industrial and EV batteries follow a different standard: removable and replaceable by an independent professional, not by the consumer. For an e-bike pack, the requirement is that a qualified independent technician can remove and replace it — including individual cells in some cases — not that the rider can.
There are two further points people miss. Software must not obstruct replacement: a product that refuses to work with a replacement battery of the correct specification does not meet the requirement. And spare batteries have to be available to end users for a period after the last unit of the model is placed on the market, at a non-discriminatory price.
Which products are affected
The categories where sealed batteries are the norm are exactly the categories where this bites.
- True wireless earbuds, where cells are glued into each bud and into the case.
- Smart watches and fitness bands with adhesive-bonded batteries behind pressed backplates.
- IoT sensors and trackers — ultrasonically welded housings with soldered coin cells.
- LED candles, decorative lighting and novelty electronics built as sealed units.
- Low-cost consumer electronics where a soldered pouch cell saves a connector and a screw.
- Electric toothbrushes, shavers, epilators — sealed for water ingress, historically with no service route.
- Bluetooth speakers and portable audio with bonded packs.
- Toys with soldered rechargeable packs.
- Vapes and single-use electronics, which are separately in the crosshairs of national bans.
If you sell any of these, the practical question is not whether the rule applies. It is whether the units your supplier plans to ship in Q1 2027 can be opened by a customer with a household screwdriver.
What "removable by the end user" means in practice
Regulators have not published a torque figure, but the intent is clear enough to design against.
Commercially available tools. A Phillips or Torx screwdriver, a plastic pry tool. Not a heat gun, not a proprietary jig, not a solvent.
No destructive disassembly. If getting the cell out breaks the housing, or a clip, or a seal that cannot be re-made, the battery is not replaceable.
No soldering. A cell soldered to the board is the clearest failure case. A connector, a spring contact, or a battery holder is the fix.
No adhesive-only retention. Cells held solely by structural adhesive fail. Adhesive with pull tabs designed for removal, plus instructions, is the common industry answer.
Instructions that a consumer can follow. Written, available with the product and online, kept available for the expected lifetime, with the safety warnings a lithium cell warrants.
A replacement that is actually obtainable. A removable battery with no spare on sale is compliance on paper only.
The pragmatic design pattern converging across the industry is: one or two accessible fasteners, a serviceable seal or gasket, a connector rather than solder tabs, pull-tab adhesive where retention is needed, a labelled cell with matching spare part number, and a QR code on the product resolving to removal instructions — which also serves the February 2027 QR requirement.
The exemptions, and why not to rely on them
Article 11 provides narrow derogations. Broadly, a portable battery may remain non-removable where:
- continuity of power supply is necessary and a direct connection between the appliance and the battery is required for safety, performance, medical or data-integrity reasons; or
- the appliance is designed to operate in a wet environment, being specifically designed to be regularly washed, or to work in conditions that require ingress protection, or is a professional medical imaging or radiotherapy device.
Where a derogation applies, the battery must still be removable and replaceable by qualified independent professionals, and the product carries information about that.
Three cautions. First, the exemptions are read narrowly: "splash-resistant" is not "designed to be regularly washed", and an IP rating alone has not been treated as sufficient. Second, the exemption removes the consumer-removability duty, not the professional-removability duty — a fully potted assembly with no service route fails either way. Third, the burden of demonstrating the derogation sits with you, in your technical documentation, and a market surveillance authority will ask for the reasoning.
Assume you are in scope unless a lawyer has told you otherwise in writing.
What this means commercially
Three consequences worth planning for.
Sourcing lead time. A design change to add a fastener, a connector and a serviceable seal is a tooling change. Tooling changes run months, and your factory will not start until you ask. A product being quoted in autumn 2026 for spring 2027 delivery has to be specified for removability now.
Spare parts as a product line. You will need to sell replacement cells, which brings its own duties: the spare cell is itself a battery placed on the market, with Annex VI markings, a producer registration, and dangerous-goods handling for shipping. Many brands underestimate this second obligation entirely.
Warranty and support. A user-replaceable battery changes your returns picture — usually for the better, since a dead cell stops being a dead product — but it needs a support script, a part number, and instructions written for a non-technical customer.
What to put in a supplier brief
Suppliers respond to specifications, not to regulation names. A brief that works reads roughly like this.
The battery must be removable and replaceable by an end user using commonly available tools. No soldered or welded cell connections — use a connector, spring contacts or a holder. Retention must be mechanical or by pull-tab adhesive; structural adhesive alone is not acceptable. Fasteners must be standard drive types accessible without destroying the housing or any non-replaceable seal. Any gasket in the removal path must be re-usable or supplied as a spare. Provide the cell part number, the electrical and mechanical specification, and confirm the spare cell can be supplied for at least five years. Supply removal and replacement instructions in editable form, with safety warnings, plus a photographed teardown of the production unit. Firmware must accept any replacement cell meeting the specification.
Ask for a sample from tooling, not a prototype, and open it yourself. The gap between what a factory confirms in writing and what arrives in the first container is the risk you are managing.
How this interacts with your other obligations
Removability is not a standalone rule; it sits inside a set of duties that touch the same product.
QR code and label information. From the same February 2027 date, portable batteries carry a QR code giving access to label information, the declaration of conformity, removal instructions and collection information. The removal instructions Article 11 requires are the same instructions the QR code serves — write them once.
WEEE treatment. A separable battery is what allows the appliance and the cell to go into their correct end-of-life streams, which is the policy behind the rule.
GPSR. Replacement introduces a foreseeable-use scenario your risk assessment has to cover: a consumer handling a lithium cell. That means warnings, instructions and, in some categories, a keyed or shrouded connector so the cell cannot be fitted the wrong way round.
Spare parts as products. A replacement cell you sell is a battery placed on the EU market in its own right, with Annex VI markings, producer registration and transport classification of its own.
The transition: what happens to stock already out there
The requirement applies to batteries and products placed on the EU market from 18 February 2027. Placing on the market is the first making available in the EU, per unit.
That means: units already placed on the market before the date are not retrospectively non-compliant, and a retailer can continue to sell through existing stock that was lawfully placed on the market. But every unit you first make available in the EU on or after the date must comply — so a container arriving in March 2027 with glued-in cells is a problem, regardless of when you ordered it.
Two practical implications. Get your EU-inbound schedule and your compliant-design schedule on the same chart, and know exactly which shipment is the first that must comply. And keep the evidence: records showing when units were placed on the market are what defend legacy stock if anyone asks.
What to do now
Audit the range. For each battery-powered SKU: is the cell removable with common tools, is it connectored or soldered, is retention adhesive or mechanical, does a documented removal procedure exist, and is a spare available. Photograph a teardown of your top ten sellers — an afternoon of work that produces an unambiguous answer.
Write removability into supplier specifications. Not "must comply with EU regulations", which suppliers will sign and ignore, but the specific mechanical requirements: connector not solder, mechanical or pull-tab retention, fastener count and type, seal serviceable, spare part number available, removal instructions supplied.
Decide the fate of the failures. For each non-compliant SKU: redesign, replace with a compliant alternative, or sell out before the date. That is a commercial decision with a deadline, and it is better made in a planning meeting than in a customs hall.
Bundle it with the other February 2027 work. The QR code requirement lands on the same date and can carry the removal instructions Article 11 requires. Doing artwork, documentation and design in one pass is materially cheaper than three passes.
