A battery dying on your scooter still has 70% left to give.
cirBATT collects end-of-life lithium batteries from small e-mobility and electric vehicles, requalifies each cell, and assembles second-life packs for stationary storage (residential solar, industrial solar, microgrids, data center UPS etc...). Each battery is tested to meet EN IEC 62619:2022, CE marking, Regulation (EU) 2023/1542, and UN 38.3.
From an e-scooter to a solar-powered home
An e-scooter battery at 80% SOH is no longer powerful enough for the road — but it can store the energy produced by solar panels for years.
From unusable battery to operational pack
Three steps: drop-off, requalification in the workshop, second life in storage. Every cell is tested before being reassembled — nothing is resold without inspection.
You drop off your battery
Online request, local drop-off point, or organized collection. The battery is logged with its origin and apparent condition.
Sorting, testing and reassembly
Each cell is characterized (SOH, resistance, safety), sorted by performance, then reassembled with our BMS into a second-life pack.
Stationary storage
The pack is sold for stationary uses: self-consumption, peak shaving, microgrids, backup power.
Whether you have a battery to give — or a need to power

Drop off an end-of-life battery
E-scooter, e-bike, moped, electric car — your battery no longer has enough power for mobility, but it still has value. Drop it off, we take care of the rest.
- Online drop-off form
- Free assessment of recoverable capacity
- Payment based on capacity, quality and safety
Find a suitable second-life pack
Need stationary storage for self-consumption, peak shaving, or a microgrid? Our packs are tested, calibrated, and guaranteed on real capacity.
- Full specifications: capacity, cycles, SOH
- Integrated BMS and safety testing
- Custom quote based on your use case
We only reassemble what we have measured
Every cell goes through the same checks before entering a second-life pack.
