This study bridges this gap by exploring consumer-driven economic obsolescence and the resulting implications for product longevity and replacement strategies. Employing a composite methodology that integrates economic modeling with net present value analysis, this article investigates the timing of optimal product replacement from the consumer perspective. It challenges the conventional minimum cost per unit time methods by introducing a profit-equating replacement strategy tailored to circular economy principles. Key findings reveal a paradoxical dynamic wherein increased technological advancement can inversely affect optimal replacement timing, underscoring a consumer-centric view of obsolescence.

The repurposing potential of EV batteries is projected to remain limited in this decade, but could significantly reduce and potentially eliminate battery imports to meet domestic BESS demand as early as 2038.
