What the programme covers
Grade A modules
Modules above 85% SOH suit higher-cycle commercial storage duties.
Grade B modules
Modules at 75–85% SOH suit telecom backup, solar buffering and lighter duty.
Matched strings
Capacity and resistance spread are controlled before modules share a string.
Safety screening
Isolation, leakage, thermal and impedance flags exclude unstable units.
Warranty evidence
Every deployed module retains its source and test record.
End-of-second-life
Take-back is built into the system so modules return for refining.
Infrastructure built for the complete battery lifecycle
From declaration to certificate
- 1
Declare
Share pack count, chemistry, state of charge, damage status and pickup constraints.
- 2
Collect

Frequently asked questions
What is a second-life EV battery?
It is a retired traction-battery module that no longer meets vehicle requirements but passes safety and capacity tests for stationary energy storage.
How long can a second-life battery last?
A correctly graded module can provide another three to eight years, depending on chemistry, temperature, cycling depth and application.
