What the chemistry means here
How it ages
LMO's weak point is manganese dissolution, which speeds up at elevated temperature and damages the anode. Packs that lived in hot climates without active cooling typically fade faster.
Thermal behaviour
Manganese spinel is more thermally stable than nickel-rich cathodes, but blended LMO-NMC pouch cells still vent flammable gas when abused, and older packs may have weaker protection electronics.
Handling LMO Pouch
Collecting a Mahindra Treo Auto pack
7.37 kWh, 4 modules, about 60 kg — this is how the Haldia, West Bengal team plans the job.
Removal

Packaging
Packs are palletised in small groups inside UN-rated boxes, with dividers between units.
Consolidation
Fleet depots and dealer service points are scheduled as recurring milk runs rather than one-off pickups.
Before the truck arrives
