Role of end users in waste prevention and separate collection: Do not discard this battery with household or mixed waste. Hand the vehicle or the removed pack to an authorised treatment facility, a VOLTA service partner or a municipal collection point. Separate collection is what lets the cobalt, lithium and nickel in this pack re-enter production instead of being lost.
Separate collection, take-back and collection points: Free take-back at every VOLTA service partner and at authorised treatment facilities in all EU member states, with no obligation to buy a replacement. Collection points: https://volta-cells.example/take-back
Preparation for re-use, repurposing and recycling operations: Packs at or above 70 % state of health are assessed for repurposing into stationary storage; the passport follows the pack and its status changes to repurposed. Below that threshold the cells go to hydrometallurgical recycling, which recovers cobalt, nickel and lithium for new cathode material.
Safety instructions for handling waste batteries: Treat the pack as live at up to 455 V. Do not open, crush, drill or immerse it. Insulate the terminals before transport and carry it as UN 3480 / UN 3481 dangerous goods. Isolate a damaged or swollen pack outdoors and call the emergency number on the rating plate.
Meaning of labels and symbols: Crossed-out wheeled bin: collect separately, never with household waste. Li: lithium-based chemistry. CE: conformity with the applicable EU legislation. The QR code on the pack resolves to this passport.

Labels & compliance
