Specialist Second Life and the Battery Passport Record

Specialist second life means a specialist battery moving to a later use that differs from its first use, whether in the same specialist setting or in a different application, and the passport record for such a battery should show the move as a status change with capability evidence for the new use. The move is not a continuation of the first use under a new owner, and it is not a simple resale, because the duty, the environment and the safety measures for the new application may differ from those of the first application. A record that shows only a change of holder, without a change of status and without capability evidence for the new use, understates the move and leaves a later reader to assume that the new use was assessed when it may not have been.

The scope is batteries within Article 77 that are prepared for reuse or repurposing, read with Article 73 for waste batteries, and with the status information in Annex XIII. The guide does not advise on the suitability of any particular second life application. The position is stated as checked on 28 October 2026.

What is the difference between reuse and repurposing for specialist batteries?

Reuse means further use of a battery for the same kind of application, while repurposing means further use for a different application, and the Regulation uses preparation for reuse and preparation for repurposing as distinct processes for waste batteries. For a specialist battery, the difference matters because reuse carries the original duty and safety assumptions forward, while repurposing requires a fresh assessment of duty, environment and safety for the new application. A battery moved from a specialist vehicle to a stationary storage role, for example in general terms, is a repurposing, not a reuse, and the record should show the new application and the evidence that the battery can deliver the performance relevant to that application. The label should match the move, and the evidence should match the label.

What evidence does Article 73 require for preparation for reuse or repurposing?

Article 73 requires, for waste light means of transport, industrial and electric vehicle batteries subject to preparation for reuse or repurposing, that the battery holder demonstrate on request by a competent authority evidence of a state of health evaluation or testing confirming capability for the later use, documentation of further use by invoice or contract, and evidence of appropriate protection during transport, loading and unloading. The state of health evidence must confirm capability for the performance relevant to the use following preparation, which for a specialist repurposing means capability for the new application, not only capability in general. The documentation model in Article 73 is therefore the template for a specialist second life file, even where the precise Article 73 test needs a case specific reading.

How should a specialist second life be recorded?

A specialist second life should be recorded as a dated status entry under the existing identifier, preserving the first life history, stating the new application, the operator responsible for the preparation, the state of health evidence, and the documentation of further use. The entry should state the date of the status change and the date of the evaluation, so that a later reader can tell whether the evaluation preceded the move or followed it. A status entry without an evaluation date, or an evaluation without a status entry, leaves the file incomplete in a way that matters, because the order of evaluation and move is part of the assurance that the move was assessed before it happened.

What does a second life record table look like?

A second life record table separates first life, preparation and second life, so that the move is visible as a sequence. The table below uses general stages, without describing any real second life.

What safety questions arise in specialist repurposing?

Safety questions in specialist repurposing arise from the change of duty, environment and safety measures, because safety measures designed for the first application may not cover the new application. The repurposing operator should read the safety measures in the legitimate interest tier, read the equipment documentation for the new application, and record the safety assessment for the new duty, rather than carrying the first application safety file forward unchanged. A repurposing that reuses the first application safety file without a fresh assessment risks missing a hazard that is specific to the new application, such as a different thermal environment or a different duty cycle. The safety assessment should be recorded with the status entry, so that the file shows the assessment as part of the move.

What happens when a specialist battery cannot be repurposed?

When a specialist battery cannot be repurposed, the record should show that conclusion and the battery should move to collection, treatment and recycling through the waste battery route, rather than being stored indefinitely or moved to an unsuitable use. A decision not to repurpose is a useful record entry, because it prevents a later holder from assuming that repurposing was never considered, and it closes the second life question with evidence. The collection and recycling route is described in the specialist collection guide in this cluster, and the passport record should link to that route by preserving the identifier and the final status, so that the end of life handling can be traced from the same history.

What limits apply to specialist second life readings?

The limits are that a record cannot prove suitability for a new application, and suitability needs application specific assessment. This guide gives general educational information only and is not individual legal advice. An operator with a specific second life proposal should check the Regulation text as checked on 28 October 2026 before acting.
