Why is proper disposal so important?
An old car battery is anything but harmless. Every starter battery – whether a classic wet battery, a modern AGM, EFB, gel or the powerful lithium-ion variant (LiFePO4) – contains hazardous substances such as lead, sulphuric acid or electrolyte mixtures that can cause massive damage to groundwater and soil if handled improperly. At the same time, an average 60–100 Ah lead-acid battery contains around 8–12 kg of pure lead, more than 95 % of which can be recycled. The German Battery Act Implementation Act (BattDG) therefore stipulates that old batteries must not go into household waste but must be returned for proper disposal. Even one incorrectly disposed battery creates a risk of fines amounting to several thousand euros – not to mention the damage to the environment's image. In this guide, read in detail where you can dispose of your old car battery free of charge and in compliance with the law – and how you can be ready to go again straight away with a new battery from our online shop.
Disposing of a car battery – the most important places to go
In principle, you have several options for handing in your old battery – all of them are free of charge and legally secured. We present the three most common routes here:
Household waste recycling centre / recycling centre
Every city and municipality in Germany operates its own household waste recycling centres or recycling centres. There you can hand in almost all battery types directly – whether a 12 V wet battery with 400 A cold cranking current, a 120 Ah AGM or even a lithium starter battery with 12.8 V. Acceptance is free of charge, regardless of the purchase date or condition (even leaking batteries are accepted in special acid trays). Particularly practical: many centres accept not only car starter batteries but also motorcycle, boat and lorry batteries. Bring your ID and, if applicable, the receipt – as a rule, however, an informal handover is sufficient.
Car workshops & vehicle businesses
If you replace the battery yourself or take your vehicle to a workshop, the staff are obliged to take back the old battery free of charge. This also applies if you are only having a tyre change or an inspection carried out – simply ask at your next visit. This is particularly worthwhile with starter batteries with high capacities such as a 95 Ah EFB or a 100 Ah gel battery, as it saves you the transport.
Online retailers & bricks-and-mortar trade – take-back under the BattDG
Since the German Battery Act (BattDG) came into force, all retailers that sell batteries are legally obliged to take back old batteries free of charge – regardless of whether you order as a private individual or a business. You can conveniently order your new AGM or LiFePO4 starter battery from us, and we will inform you during the ordering process about the correct return of the old battery. Please understand that, for organisational reasons, the return of the old battery cannot be made via free DHL shipping, but our support colleagues will be happy to help you by phone (+49 7135 7194106) or email ([email protected]) with the legally compliant process. The return address is: Electronicx GmbH, Hindenburgstraße 37A, 74389 Cleebronn.
Recycling car batteries – a closed loop
A modern 12 V lead-acid starter battery achieves a recycling rate of over 98 % – which means that almost all raw materials flow back into production. The high-quality lead (around 60–70 % of the weight of a 74 Ah battery) is melted down and processed into new battery grids; the polypropylene casing is washed, shredded and turned into new plastic granules; even the sulphuric acid can be neutralised or reprocessed. This closed raw material loop reduces energy input by 50–70 % compared with primary production. So anyone who disposes of their old battery carefully makes a significant contribution to climate protection and at the same time helps secure the supply of critical metals.
AGM, EFB, gel, flooded or lithium – what should be considered when disposing of them?
Not every battery type is treated in the same way, even though the statutory take-back obligations apply to all of them. Most conventional starter batteries are lead-acid variants, for which the established recycling system applies when they are disposed of. Lithium iron phosphate starter batteries (LiFePO4), on the other hand, require separate logistics, as they contain no liquid acid but do contain flammable electrolytes.
Lead-acid batteries (flooded, AGM, EFB, gel)
All of these types work with a nominal voltage of 12 V and deliver cold cranking currents (CCA) of around 300 A for small 36 Ah flooded batteries up to 900 A for high-performance 105 Ah AGM batteries. Cycle life varies considerably: a simple antimony flooded battery achieves around 200–300 cycles, a modern AGM lasts 400–600, an EFB 300–500 and a gel battery even 500–800 cycles at 50 % depth of discharge. What they all have in common is lead-acid chemistry, so take-back takes place wherever these batteries are sold – from DIY stores to online retailers. Important: make sure you transport the battery upright to prevent acid from leaking out.
Lithium-ion starter batteries (LiFePO4)
However, their disposal is not yet as comprehensively standardised as that of lead-acid batteries. In principle, you can hand in LiFePO4 batteries at municipal collection points for lithium batteries or take them to a retailer that stocks lithium starter batteries. Improper handling (e.g. deep discharge below 2.5 V per cell or mechanical damage) poses a fire risk, which is why separate collection is crucial.
| Battery type | Voltage | Capacity range (Ah) | CCA range | Cycles (50% DoD) | Disposal route |
|---|---|---|---|---|---|
| Flooded battery | 12 V | 36–100 Ah | 300–800 A | 200–300 | Lead-acid recycling, everywhere |
| AGM | 12 V | 60–110 Ah | 600–900 A | 400–600 | Lead-acid recycling, everywhere |
| EFB | 12 V | 50–95 Ah | 500–800 A | 300–500 | Lead-acid recycling, everywhere |
| Gel | 12 V | 70–120 Ah | 500–800 A | 500–800 | Lead-acid recycling, everywhere |
| LiFePO4 | 12,8 V | 20–200 Ah | 500–1500 A | 2.000–5.000 | Lithium collection, special take-back |
BattDG: your rights and obligations when returning an old battery
The German Battery Act (BattDG) governs the placing on the market, take-back and environmentally sound disposal of batteries and rechargeable batteries in Germany. As a consumer, you are obliged under the BattDG to consign waste batteries to a collection separate from unsorted municipal waste. Free return to retailers is also laid down by law: retailers must take back waste batteries that they stock or have stocked free of charge from the end user – even if the customer does not buy a new battery. Also pay attention to the symbols: the crossed-out wheelie bin symbol on the battery reminds you of this obligation.
- Waste batteries must not be disposed of in household waste or the yellow bag.
- Take-back is always free of charge for private individuals and commercial users.
- Online retailers must offer a postal return option; the cost of return is generally borne by the consumer (exception: when buying a new item, the retailer may enclose a returns label – please clarify this in advance).
- Batteries containing pollutants (lead, cadmium, mercury above the limit values) must be clearly labelled.
Safe transport and storage – how to avoid hazards
Until you take your old car battery for disposal, it must be stored safely in the interim. Open lead-acid batteries and deeply discharged lithium cells in particular carry risks:
- Lead-acid batteries should always be stored upright, with the terminals covered using the supplied protective caps or insulating tape to prevent short circuits. A cool, ventilated room (e.g. a cellar or garage) is ideal, as extreme cold can freeze the electrolyte and burst the casing. Leaking batteries should be placed immediately in an acid-resistant container and taken to the recycling centre as soon as possible.
- LiFePO4 batteries must never be mechanically damaged, must not be exposed to temperatures above 60 °C, and particular caution is required with deeply discharged cells (below 2.5 V per cell) – risk of fire! Here too: insulate the terminals and transport in the original packaging or in a sturdy cardboard box with appropriate padding.
Transport in your own car is permitted provided the battery is placed securely and well secured in the passenger compartment. Tipping over or rolling must be ruled out. For commercial transport (e.g. for take-back to our address), the dangerous goods regulations apply, which you can clarify with our support in advance.
Frequently asked questions about car battery disposal
Where can I hand in my old car battery free of charge?
You can hand in your waste battery free of charge at the recycling centre, at car workshops, at retailers (including online retailers) and at our Electronicx GmbH in Cleebronn. Take-back is required by law and is free of charge for you.
Do I have to return an old battery when buying a new one?
No, you are not obliged to return an old battery in order to buy a new one. The retailer must take back waste batteries free of charge even without a new purchase (BattDG). However, disposing of your old battery properly regardless of a new purchase is an active contribution to environmental protection.
Do scrapyards accept car batteries?
Many scrapyards accept car batteries, as lead and other metals have a high material value. Nevertheless, you should first use municipal collection points or retailers, as proper collection and recycling is reliable there. Ask by telephone beforehand whether they accept them.
Can I dispose of a defective car battery in household waste?
No, that is strictly prohibited. Car batteries contain toxic heavy metals and acids and must be collected separately. Even a 60 Ah battery can significantly contaminate groundwater. Illegal disposal in residual waste or in the environment is punished with high fines.
How do I store an old battery safely until disposal?
Store lead-acid batteries upright, cool and dry; the terminals should be covered with insulating tape or protective caps. LiFePO4 batteries should additionally be protected against mechanical damage and extreme temperatures. Deeply discharged lithium cells are particularly prone to fire and should be handed in for proper disposal as quickly as possible.
Is it also possible to return car batteries online?
Yes, online retailers such as Electronicx are legally obliged to take back old batteries. They provide information on the exact procedure during the order process or on request. As a rule, you can send the old battery to our warehouse address; return shipping is not always free of charge – please clarify this in advance with our customer service ([email protected]).
Do the same rules apply to motorcycle and lorry batteries?
Yes, the German Battery Act does not distinguish between vehicle categories. Every lead-acid or lithium starter battery – whether for a motorcycle (6 V/12 V, e.g. 12 Ah) or a lorry (24 V via two 12 V batteries in series) – is subject to the same take-back obligations. Boat batteries (leisure batteries) are also included.
