A Partial Reprieve for Waterproof Devices as the EU's 18 February 2027 Battery Deadline Nears

Article 11 of Battery Regulation (EU) 2023/1542 applies from 18 February 2027, and it requires portable batteries built into products to be removable and replaceable by the end user. Waterproof consumer electronics get a partial exemption: where necessary for product safety, the battery may instead be replaceable only by an independent professional. That relief does not switch off the rest of Article 11 — spare-parts availability, instructions, cross-brand compatibility and software neutrality still apply.

With roughly five months to the deadline, importers of IPX7 cordless oral care devices are in the window where a design decision still costs tooling money rather than market access.

What Article 11 actually requires

Per the compliancegate.com guide (July 8, 2026) and the EUR-Lex summary:

• Portable batteries must be removable and replaceable by the end user, as a whole battery rather than individual cells. A "portable battery" is sealed, weighs 5 kg or less, and is not industrial, EV, LMT or SLI.

• Removal must be possible with commercially available tools — a screwdriver, for example — or with specialised tools provided free of charge with the product, and should not require proprietary tools, thermal energy, solvents or a service centre.

• Instructions for removal and replacement must come with the product and be available online.

• It must be possible to fit a compatible battery of another brand without affecting functionality, performance or battery safety, and software must not negatively affect a replacement battery.

• The battery type must be available as a spare part for at least five years after the last unit of that model is placed on the market.

The water-exposure exemption is narrow

Batteries may be replaceable only by an independent professional where that is necessary for product safety in "electronic appliances used for operating in or exposed to water". The same clause covers professional medical imaging and radiotherapy devices and in-vitro diagnostic medical devices.

That is the clause a sealed, IPX7-rated cordless device would most plausibly rely on. It is a partial exemption. Cross-brand battery compatibility, instructions in the box and online, software neutrality, and the five-year spare-parts obligation can all still bite on a device whose battery is opened only by a professional.

What non-compliance costs, and what is grandfathered

A product that does not meet Article 11 cannot be CE marked and therefore cannot be sold in the EU; non-compliant products already on the market can be subject to recalls.

Units placed on the EU market before 18 February 2027 are not subject to the spare-parts obligation, and existing stock need not be discarded. But a model that continues to be placed on the market after the deadline must comply.

Two precedents cited by compliancegate suggest brands will converge on a single global SKU rather than build an EU-only variant: Nintendo was expected to launch an EU version of Switch 2 and its accessories with user-replaceable batteries, and Apple replaced Lightning worldwide shortly after the EU USB Type-C requirement.

Reported new exemptions — verify before relying on them

Industry tracker ecocomply.ai reported on August 22, 2026 that six new exemptions were adopted in July 2026. The specifics could not be confirmed from the source page, so this should be treated as reported only: check the Official Journal and Commission guidelines before relying on any new relief. Article 11(4) also lets the Commission add further exemptions, so the list may keep moving.

Separately, Ecodesign Regulation (EU) 2023/1670 is sometimes quoted in this debate, but it covers only smartphones, other mobile phones, cordless phones and slate tablets — not toothbrushes or water flossers. Its conditions (at least 83% of rated capacity after 500 full charge cycles, at least 1,000 cycles with 80% remaining capacity, and an IP67 rating) are a useful engineering benchmark, not a legal route for oral appliances.

Article 11 is one instrument among several

A device running on a 3.7 V cell charged at 5 V USB-C sits outside the Low Voltage Directive 2014/35/EU, which covers inputs of 50–1,000 V AC or 75–1,500 V DC. CE marking for such a product typically rests on the EMC Directive 2014/30/EU, RoHS 2011/65/EU, the General Product Safety Regulation (EU) 2023/988 and the Battery Regulation — plus RED 2014/53/EU if there is a radio. The mains-connected charger is in LVD scope. Confirm scope with your test lab rather than treating this as a legal conclusion.

Questions to put to the factory now

• Can the battery be removed with a commercially available tool, and if not, is professional replacement documented as a safety necessity?

• Is the battery type committed as a spare part for five years after the last unit ships, and will a third-party compatible cell work without a firmware lock?

• Do the removal and replacement instructions ship in the box and appear online?

Manufacturers supplying this category to EU distributors include Zhejiang-based OEM/ODM producer Charmhome, which lists ISO 13485, CE and FCC certification for its IPX7 cordless water flossers and sonic brushes.
