Oct 23, 2026

Uploaded by Margaret

Critical guidance for recycling vehicles’ 12 V Li-ion starter batteries when voltage is too low and the contactor has opened, leaving the battery effectively “dead.” The bulletin explains affected models and revision history, then distinguishes workshop handling based on whether the battery is classified as normal or warning. For warning status, it outlines irreversible steps to document and prepare shipment, including Redwood portal packaging and scheduling.
