ROI Calculation Logic

Assuming an enterprise operates 10,000 IoT devices, implementing this technology could halve battery replacement frequency from two times per year to one. With an estimated replacement cost (battery + labor) of $16.50 (AI est.) per device, the annual cost reduction is 10,000 devices × (2 replacements - 1 replacement) × $16.50/device = ~$165K (AI est.).
