For UK EV owners, as reviewed on 12 August 2026, replacement is Red and ProfessionalOnly when the 12 V battery is service-only, inaccessible or lacks an authoritative owner procedure. A workshop direction, uncertain model or undocumented access is a stop boundary, not a gap to fill from another vehicle; the correct next step is a qualified workshop booking.

Service-only, inaccessible or undocumented 12 V replacement is classified Red and ProfessionalOnly.
A workshop-only instruction, uncertain model or absent authoritative owner procedure stops owner replacement.
The handoff is the specified manufacturer-authorised repairer or an appropriately qualified EV workshop.
Stop owner replacement when the handbook requires servicing, access is restricted or no authoritative owner procedure exists, and use a qualified workshop.
The absence of an owner procedure does not create permission to infer one. When the handbook reserves service to a workshop, or the battery and access cannot be matched to authoritative vehicle guidance, no removal, fitting or reset steps are publishable.
A workshop-only maintenance decision does not establish the vehicle's driving condition; warnings and unstable systems require separate professional assessment.
Immediate action: Identify the workshop direction in the exact handbook and book the specified professional service.
The absence of an owner procedure does not create permission to infer one. When the handbook reserves service to a workshop, or the battery and access cannot be matched to authoritative vehicle guidance, no removal, fitting or reset steps are publishable.
