Collected via Ulsan, South Korea
Whole packs enter the network at Ulsan — Korea Recovery Campus, 4,637 km away, where they are weighed and de-energised.
- 2
Module grading at Tuas, Singapore
All 2 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Zwickau, Saxony
At 80% SOH about 47% of the pack qualifies for reuse and goes to Zwickau — Saxony Second-Life Works (9,976 km). Good — grade-A modules above 80% SOH qualify for commercial-scale BESS strings.
- 4

Inside the Bajaj Chetak 3501 battery
The Bajaj Chetak 3501 (2024) carries a 3.5 kWh NMC 811 Cylindrical 2170 pack with 2 modules at 50 V, weighing roughly 20 kg. High-nickel cylindrical cells with the strongest hydrometallurgical recovery credit per tonne of black mass.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 95.4% | A — BESS ready | USD 221 |
| Year 4 | 91.1% | A — BESS ready | USD 212 |
| Year 6 | 86.8% | A — BESS ready | USD 203 |
| Year 8 | 82.5% | B — Second life | USD 178 |
| Year 10 | 78.2% | B — Second life | USD 155 |
What the chemistry means here
How it ages
NMC 811 loses capacity through a mix of SEI growth, cathode surface reconstruction and micro-cracking of nickel-rich particles. Resistance climbs faster than in LFP, which matters as much as capacity for second-life duty.
Thermal behaviour
High-nickel NMC cathodes release oxygen as they decompose, so once runaway starts it is fast and energetic. Cylindrical 2170 cells vent through a designed rupture point, which helps, but cell-to-cell propagation inside a tightly packed module is the main hazard.
Handling NMC 811 (2170)
Collecting a Bajaj Chetak 3501 pack
