Second life for batteries

Rebuilt/repaired batteries are cheap, local, reliable and light on the environment

About Yedlik

Yedlik targets the environmental and economic madness of discarding broken-but-repairable li-ion batteries. 

Recycling is only a part solution to the global growing electrical waste problem. Millions of good quality cells are being recycled which could much more efficiently be repurposed for use in e-bikes, boats, golf carts, or anything that needs cordless power.

Yedlik develops repair methodology, compatible parts, and rigorous diagnostics to extend the lifecycle of li-ion batteries. We learn hands-on by running our own e-bike battery workshop, which is open to the general public, as well as serving corporate customers.

Our experienced team of engineers is located in Oslo and has already worked with thousands of batteries, provided 13 bike stores with battery solutions, and has developed dozens of unique tools to make the battery repair process more efficient.

Mission and vision

Why: We want to live in a truly sustainable world. No bullshit.

How: We make electric transportation live up to its promise of sustainability.

What: We offer repairs, rebuilds, and repurposing for mobility batteries.


Our insight is that a very large part of the discarded/recycled lithium ion cells - and often entire batteries! - are still perfectly good at storing energy, but:

  • They are in the same module with bad cells

  • The BMS died, fuse blew, the connector or the housing got damaged

  • There is no longer need of that particular battery


At the same time, a lot of electric vehicle owners are left without batteries. Scooters, bicycles, and cars get prematurely discarded because of this.


The solution is:

  • Swapping connectors, switches, housing components, fuses, and BMSs

    • Many are proprietary, but most can be sourced from the waste stream

    • Compatible BMSs must be produced

  • Dismantling batteries, and classify cells - turning them into a raw material for new batteries!

  • Building new low cost batteries from these used cells to keep old vehicles on the roads


The Battery Ecosystem

A typical battery is made up of dozens of cells and various other components. If any one of them fails, the whole battery fails. This usually results in the battery being sent for recycling. We are big fans of recycling and believe it is an important part of the waste management hierarchy, but it also uses large amounts of energy and has a substantial carbon footprint. Sending batteries to be recycled prematurely skips an important step in the waste management hierarchy - reuse and repurpose. It is a much more efficient use of materials to reuse or repurpose the cells which are working.


Some of the minerals needed to produce a lithium ion cell are extremely rare and are often mined under dangerous conditions from child labour: an estimated 35,000 children work in Congolese cobalt mines! Naturally, we want to see minerals extracted in a sustainable way and we want to see the maximum potential use from these materials as they are finite. It is important to use lithium-ion cells to their full potential before sending them to be recycled. The repurposing of cells into other devices adds sustainability and circularity to an industry that is growing rapidly.

There is a changing regulatory landscape facing the battery industry. The EU is committed to improving the circular economy and in May 2020 adopted the Circular Economy Action Plan. It states that the Commission will propose revisions to the current Battery Directive and promote more circular business models with a reduction in virgin material consumption and the establishment of new ‘rights to repair’. In order for businesses to become more circular, they will need to engage with end-of-life solutions such as Yedlik. Yedlik sees the inevitable regulation in this area as a fantastic opportunity to leverage our expertise and know-how to provide environmentally friendly solutions for battery users.
