- Open to everyone: no login, no app, no cookie wall over the content. Must load quickly on a phone.
- Stays online for at least 10 years after the last unit with this battery is placed on the EU market. Replacement instructions stay online permanently (Art. 11(1)).
- Content must be complete, up to date and accurate (Art. 13(6)). Show the update date and keep a change log.
- Languages: English plus the language of every country where distributors sell. Pick the language from the browser and let the visitor switch (Art. 74(1), Art. 38(1)(a)).

- Batch number and date of manufacture stay on the battery. The page explains where to find them.
- Who owns what: battery data and the declaration come from the battery manufacturer (the pack supplier) and are published by Dark Project under a written agreement (request item B3a). Device, replacement and spare-part content: Dark Project. Collection information per country: the distributor or its take-back scheme.
- Update the page when: a new device model uses this pack; a country or distributor is added; the declaration changes; the EU labelling implementing act is published; a take-back scheme changes.

Where to buy
Recycling
Required on this pageBasis: Art. 13(6) giving access to Art. 74(1)(b) and (c). Source: general text by Dark Project; country text and collection link from the distributor or its take-back scheme (3.5). Owner: distributor, checked by the PM.
Do not throw batteries or electronic devices away with household waste. Used batteries are collected separately so they can be recycled safely.
- You can return used batteries free of charge, without buying anything.
- Take the battery out of the device first if you can do it safely (see Replace the battery). Otherwise hand in the whole device.
- The device itself is electronic waste. Take it to a collection point for electrical and electronic equipment.
What happens to your battery
Collected batteries are sorted by chemistry and sent to licensed recyclers. They recover metals such as cobalt, lithium and copper for new products. A battery that still works can serve as a spare for the same device model.
Safety with used batteries
Required on this pageBasis: Art. 74(1)(d). Source: standard Dark Project text for lithium-ion, checked against the supplier's safety data sheet (A15). Owner: PM.
- Before you return a used battery, cover the contacts or connector with tape, or put the battery in its own plastic bag.
- Never crush, puncture, open or short-circuit a battery. Keep it away from heat and fire.
- If a battery is swollen, damaged, hot or smells unusual, stop using and charging it. Put it on a non-flammable surface away from anything that can burn, and take it to a collection point separately. Tell the staff it is damaged.
- If liquid from the battery gets on your skin or in your eyes, rinse with plenty of water and get medical advice.
- Keep batteries away from children.
In an emergency anywhere in the EU, call 112.
Lithium batteries thrown into household waste are a frequent cause of fires in bins, collection trucks and sorting plants.
Make the battery last longer
Required on this pageBasis: Art. 74(1)(a). Source: standard Dark Project text, charging limits from the supplier (A3, C10). Owner: PM.
- Charge with the supplied USB cable from a computer port or a 5 V USB charger.
- Avoid running the battery completely flat.
- If you will not use the device for more than a month, leave the battery about half charged and top it up every 3 months.
- Do not charge below 0 °C or above 45 °C, and keep the device out of direct sun and away from heaters.
- When the battery wears out, replace the battery, not the device.
What the symbols mean
Required on this pageBasis: Art. 74(1)(e). Source: symbols on the approved pack artwork (A16, part B). Owner: PM. List only the symbols that are actually on this battery, plus the bin on the device.
- Crossed-out wheeled bin. Collect separately. Do not put the battery, or the device that contains it, in household waste. The same symbol on the device marks it as electronic waste.
- CE marking. The battery meets EU requirements. See the declaration of conformity.
- Chemistry. Lithium-ion battery.
- Capacity. The amount of charge the battery holds when new. The energy in watt-hours is shown next to it.
- QR code. Opens this page.
- Cd Pb
- Cd or Pb under the bin. The battery contains more than 0.002 % cadmium or more than 0.004 % lead.
Effects on health and the environment
Required on this pageBasis: Art. 74(1)(f). Source: standard text plus this battery's substances (A10, A11). Owner: PM.
- A damaged battery, or one thrown into household waste, can short-circuit and catch fire. Burning lithium batteries release toxic and corrosive gases.
- Batteries that are littered or end up in landfill can release metals and electrolyte into soil and water, harming people, animals and plants.
- Separate collection and recycling avoid these risks and return valuable materials to production.
