Interested in our stock of cells?

We supply professionals with tested, sorted and documented second-life lithium-ion cells. Reconditioners, pack assemblers, integrators, repair shops — let's talk volume, chemistry and grade.

What we supply

Measured cells, not cells sold “by weight”

We disassemble end-of-life mobility and EV batteries, then characterise every cell before offering it. You receive qualified material, with its data.

01

Cylindrical 18650 & 21700

LFP and NMC chemistries, from scooters, e-bikes, mopeds and EV packs. Other formats on request.

02

Tested one by one

Real capacity (Ah), internal resistance (mΩ), SOH and a safety check measured cell by cell on a test bench.

03

Sorted and matched

Grouped by SOH, capacity and chemistry into homogeneous batches, ready to use in assembly.

04

Documented & traceable

A measurement sheet per batch, chemistry and origin. You know exactly what you build into your products.

Our grades

A grade for every use

Cells are graded by their real state of health. Below 70% SOH they are not resold — they go to material recycling.

Grade SOH Typical use
A≥ 90%Premium pack assembly, heavy duty
B80 – 90%Stationary storage, solar self-consumption
C70 – 80%Low-duty storage, backup power
Why cirBATT

A supplier that measures before selling

  • Cell-by-cell sorting. No cell enters a batch without being characterised on a charge/discharge bench.
  • A standards-aligned process. Our batteries are tested to meet EN IEC 62619:2022, CE marking and UN 38.3.
  • Regular volumes. A steady flow of cells from our collection activity, for recurring supply.
  • Based in France. Workshop in Grenoble, a dedicated technical contact, European logistics.
