Where a Mahindra XEV 9e pack goes from Haldia, West Bengal
- 1
Collected via Khordha, Odisha
Whole packs enter the network at Bhubaneswar — Khordha Collection Yard, 331 km away, where they are weighed and de-energised.
- 2
Graded at Pithampur, Madhya Pradesh
Modules travel 1,279 km to Indore — Pithampur Grading Plant for capacity, resistance and impedance testing across all 18 modules.
- 3
Second life at Butibori, Maharashtra
At 80% SOH about 56% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (956 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refining at Haldia, West Bengal
Black mass from failed modules is leached and refined here into battery-grade lithium salts.

Inside the Mahindra XEV 9e battery
The Mahindra XEV 9e (2025) carries a 79 kWh LFP Prismatic (LiFePO4) pack with 18 modules at 400 V, weighing roughly 585 kg. Cobalt-free prismatic chemistry dominant in Indian passenger EVs and commercial fleets. Low black mass value, exceptional second-life economics.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 95.7% | A — BESS ready | USD 4,123 |
| Year 4 | 92.6% | A — BESS ready | USD 3,992 |
| Year 6 | 89.5% | A — BESS ready | USD 3,862 |
| Year 8 | 86.4% | A — BESS ready | USD 3,706 |
| Year 10 | 83.3% | B — Second life | USD 3,110 |
What the chemistry means here
How it ages
LFP fades slowly and fairly linearly for most of its life. Capacity loss is driven mainly by lithium inventory being locked up in the SEI layer on the graphite anode, while the cathode structure stays largely intact.
Thermal behaviour
LFP's olivine cathode holds its oxygen tightly, so thermal runaway typically starts at higher temperatures than nickel-rich cells and releases noticeably less heat. It is not inert: a failing LFP cell still vents flammable electrolyte vapour and hydrogen, and large prismatic cans store a lot of energy in one place.
Handling LFP Prismatic
Collecting a Mahindra XEV 9e pack
79 kWh, 18 modules, about 585 kg — this is how the Haldia, West Bengal team plans the job.
Removal
Packs are dropped on a vehicle lift using the OEM procedure and a rated battery table, then isolated at the service disconnect.
Packaging
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed.
Consolidation
Dealer and workshop returns are consolidated into full truckloads, typically eight or more packs per run.
Before the truck arrives
- Pull the service disconnect and record pack voltage
- Drain or cap coolant lines before lifting
- Photograph the pack casing and any impact damage
- Keep the VIN and pack serial together on the manifest
