Recommended Spoken Script
"Our contract specifies that warranty claims resulting from thermal dendrite formation are 100% cell manufacturer liability, provided the OEM Battery Management System operated within standard thermal ranges of 15°C to 35°C. Verified cloud telemetry logs prove the thermal limits were maintained, establishing full supplier warranty replacement obligations."
