EU Battery Regulation: what the new rules mean for batteries in used devices

The duty covers newly delivered devices, not the ones already out there, according to Stiftung Warentest, the German consumer-testing institute.

And "replaceable" doesn't automatically mean a snap-off back cover like your old Nokia. Manufacturers get two routes, per connect.de:

• a battery you can swap yourself with commonly available tools, or

• a fixed battery that still holds at least 83 percent of its capacity after 500 charge cycles.

One more thing: spare batteries have to stay available for five years after a model's last sale.

The digital battery passport lands on the same date, and this is where it gets disappointing for used-device buyers. From February 2027 it is mandatory only for batteries in light transport such as e-bikes and e-scooters, plus industrial and vehicle batteries, according to the German environment ministry. Phone and laptop cells aren't in scope. (Search for "battery passport" and you mostly get carmakers and supply-chain software. Took me a while to work out that this is the actual use case.)

Collection targets are climbing in the background too, to 63 percent by the end of 2027 and 73 percent by the end of 2030. Germany added its own implementing act, the BattDG, on 7 October 2025. Both of those land on manufacturers and recyclers rather than on you at checkout.

No, and what matters here is timing: individual product units placed on the market before that date won't need to comply, per a legal analysis by Fieldfisher, because it's the specific unit's first sale date that counts, not a calendar switchover for the whole EU market.

So the market you're shopping in today consists entirely of hardware from before 2027, and used devices keep changing hands for years, which means that stays true well past the deadline. We covered the new-device side in Removable batteries and the digital battery passport from February 2027.

Concretely: an iPhone 15 that first went on sale in 2024 can still legally sit on a refurbished shelf in 2028 or 2030 with a glued-in battery. The cutoff date tracks the device's first sale, not the calendar.

The EU Battery Regulation is its own instrument: as Right to Repair Europe sets out, it is one of several product-specific legal bases that the separate repair directive refers to.

As long as no law forces battery transparency for phones, it stays voluntary. Two things therefore matter more than the regulation does.

First, the stated battery health percentage, the State of Health figure. Some sellers give you a real number, some write "at least 80 percent", some say nothing at all. What that figure is worth is in our piece on battery quality in refurbished devices.

Second, the warranty and statutory guarantee terms, because that's your only real lever if the battery collapses four months in. Our warranty guide sorts out who promises what. Until the EU Battery Regulation's swappable-battery rule reaches phones in 2027, battery health and warranty terms stay the only reliable levers you have when buying used.

In the used EV market a documented battery certificate has already turned into a price-negotiation tool, as Auto Motor und Sport reports. Phones are nowhere near that. I'd guess this gets solved by sellers competing on transparency rather than by Brussels, though I could be wrong about the timing. Asking costs nothing either way, and a seller who won't state the battery health usually has a reason.
