A home battery is not disposed of via normal waste at the end of its life, but via the established battery take-back system – professionally and never on your own, because large batteries must be treated with care. Valuable raw materials are recovered during recycling. For you as the owner, the topic is usually only relevant after many years; the return is organised by the specialist company. (As of: July 2026)
Key points in brief
- Battery storage does not belong in household waste, but in the battery take-back system.
- The disposal is carried out professionally by the specialist company – never through self-dismantling.
- In recycling, raw materials are recovered from the cells; what exactly, depends on the cell chemistry.
- The topic usually only becomes current after many years, because batteries last a long time.
- This article explores the battery part of the dismantling in more depth – for the entire system, the article on recycling solar systems applies.
When does the disposal of a battery become an issue at all?
Usually only late – and that is the first reassuring news. A home battery lasts many years, as the article on lifespan describes: Only when its usable capacity has dropped so much after cycles and calendar years that it hardly yields anything anymore, does the question of replacement and disposal arise. For most owners, this moment lies far in the future.
In addition to the regular end of life, there are two other occasions: a defective battery that cannot be repaired, or a conversion where the battery is replaced. In all cases, the same path applies – the old battery is returned professionally, not disposed of like an ordinary electrical appliance.
The distinction from the dismantling of the entire system is important. How modules, inverters and mounting structures are dismantled and recycled at the end of their life is described in the article on the recycling of solar systems. This article here explores the special part of it in more depth: the battery, which has its own rules.
Why must a battery not go into normal waste?
Because a large battery is not harmless e-waste. It contains stored energy and materials that must be treated professionally – for safety and environmental reasons. An improperly treated or damaged battery can pose a risk, which is why dismantling belongs in expert hands.
Therefore: never dismantle it yourself. Removing and disconnecting a large home battery is a matter for the specialist company, just like the installation. It safely disconnects the battery from the system, secures the battery for transport and hands it over to the take-back system. For you as the owner, this means: You do not organise disposal at the DIY store, but commission the dismantling from a specialist company.
The battery take-back system in Switzerland ensures that batteries do not end up in the waste, but are collected and recycled. The return is integrated into this established system – no special route, but the regular channel for batteries.
What happens to the battery in recycling?
It is dismantled, and valuable raw materials are recovered from the cells. A battery is a material storage – and exactly that makes recycling sensible, because the metals it contains are valuable and can be reused.
Which raw materials are specifically recovered depends on the cell chemistry. The article LFP vs. NMC describes the common battery types; they differ in the materials used and thus also in what comes out during recycling. Basically, the process aims to separate the contained metals and return them to the cycle instead of losing them.
A growing topic alongside pure recycling is reuse. Some batteries that no longer have enough capacity for demanding home use are still suitable for less demanding applications – a second life before they are ultimately recycled anyway. Whether and how this is sensible in individual cases is decided by the condition of the battery.
| Route | What happens | When |
|---|---|---|
| Reuse | Battery continues to serve in a less demanding application | if residual capacity is still sufficient |
| Recycling | Dismantling, recovery of raw materials | at the final end of life |
| Professional dismantling | Removal by a specialist company, handover to the take-back system | in any case |
Orientation, As of: July 2026. The applicable take-back and disposal regulations are decisive.
The question of disposal often comes up already during the purchase – «and what happens to the thing when it is broken?». Our answer takes away the worry: The battery lasts many years, and at the end there is a regulated path via the battery take-back system. What we emphasise is the safety aspect: No one removes a large battery themselves, just as no one installs one themselves. We take over the dismantling in the same move as a possible new installation. And we point out that a worn-out battery sometimes still has a second life ahead of it before it is recycled.
Frequently asked questions
Does the disposal of a battery cost extra?
The effort lies above all in the professional dismantling by the specialist company. The return of the battery takes place via the established take-back system. What the costs look like in individual cases depends on the situation – this is best clarified with the specialist company that carries out the dismantling. Disposing of it via waste is in any case not an option.
Can I simply take my old battery to the recycling centre?
No. A large home battery is not for the recycling centre or household waste and should also not be removed on your own. Dismantling belongs to the specialist company, which safely disconnects the battery and hands it over to the take-back system.
What is a «second life» for batteries?
Batteries whose capacity is no longer sufficient for demanding home use can sometimes be reused in less demanding applications before they are recycled. Whether this makes sense in individual cases depends on the condition of the cells. At the end of this second life is then regular recycling.
Is battery recycling sensible at all or purely a compulsory exercise?
It is both regulated and economically sensible. Batteries contain valuable metals whose recovery saves resources. The take-back system ensures that these raw materials are not lost. For the environmental balance of a battery, professional recycling at the end of its life is an important building block.
