How to Dispose of a Power Bank: Battery Box or Not?
5 min read
As of 06.08.2026 · Every rule below is a German rule.
An old power bank sits in a drawer for months, and eventually the question comes up: battery box at the supermarket, recycling yard, or electronics bin? Most guides get one half of that right and the other half wrong.
These are two questions, not one. What is the device, legally? And what condition is it in? Different sources, different routes.
Question 1: battery, or electrical appliance?
A plain power bank with no extra function counts as a device battery rather than an electrical appliance, according to Stiftung EAR, Germany's official register for batteries and e-waste. Ordinary battery collection is where it belongs. A charge display and extra charging ports change nothing.
Only where the power bank carries an extra function does Stiftung EAR also treat it as an electrical appliance, putting it on the e-waste route instead. Extra functions in this sense include:
Solar panel
Wireless charger
AC socket
Radio
Lamp
Alarm clock
So take a quick look at the casing first.
Handing it in is free. Under § 14 BattDG every retailer must take back waste device batteries at no charge, whatever their condition or origin, even if the power bank came from elsewhere.
Question 2: is the cell damaged?
This is where the collection box really is the wrong place.
Retailers still have to accept a damaged or swollen power bank, per the Umweltbundesamt, last updated 18.03.2024. The question is not whether, but how you hand it over. If yours is swollen, it is worth checking the power bank recalls 2025/2026 list first. Some manufacturers replace an affected unit for free instead of just taking it back for disposal.
The GRS safety standard of September 2023 requires damaged lithium batteries to be individually secured against short circuit before disposal, for instance by taping the terminals. A swollen unit dropped loose into an unstaffed slot does not meet that.
Why it matters: in 2025 alone the waste industry association BDE counted, by its own tally, more than 120 fires nationwide in recycling and sorting plants, depots and collection vehicles, caused partly by wrongly discarded lithium cells.
Until handover, a unit in that state has no business next to anything flammable. If you'd rather not leave it out in the open, pack it in a fireproof lipo pouch.

Federal law and local practice are two different layers
Two things are the same everywhere in Germany. The battery-or-appliance classification, and free take-back in shops.
How a defective unit is handed over on the ground is set by each municipality. In Berlin, BSR advises bringing a defective power bank sealed to the nearest collection point and telling staff about the fault. That is Berlin practice, not a national rule.
When in doubt, a call to the local recycling yard tells you how to hand in the power bank there.
Dispose of a power bank, or keep using it?
Not every old power bank does. If yours still gets through the day, keep using it. It's the cheapest option and the cleanest one.
Replacement earns its money when runtime has visibly dropped, or when the casing starts to bulge. The Stiftung Warentest 2026 safety test shows how safe current models actually are. All 24 units tested passed. A built-in cable on a new unit saves the part that usually goes missing first.

Frequently Asked Questions
Does a power bank belong in the battery box?
An intact one with no extra function, yes. Stiftung EAR classifies it as a device battery rather than an electrical appliance, so the collection box in a German shop is the intended route. Where the unit carries an extra function such as a solar panel, a lamp or an AC socket, it counts as an electrical appliance too and belongs in e-waste collection instead.
What should I do with a swollen or damaged power bank?
No charging, no opening, and never loose into a collection box. The GRS safety standard of September 2023 requires individual short-circuit protection for damaged lithium batteries, for example by taping the terminals. Until handover, keep it away from anything flammable. German retailers still have to accept it, per the Umweltbundesamt.
Does returning a power bank cost anything?
No. Section 14 of the German BattDG obliges every retailer to take back waste device batteries free of charge, regardless of condition, brand or origin. That means the power bank does not have to have been bought where it is handed in. BattDG has applied since 07.10.2025 and replaced the earlier BattG.
Where does a power bank with a solar panel go?
Into e-waste collection. Stiftung EAR names an integrated solar panel, wireless charger, AC socket, radio, lamp and alarm clock explicitly as extra functions that also make a power bank an electrical appliance. It then falls under both sets of rules, and the e-waste route is the correct one.
