If you are a compliance manager responsible for LMT (light means of transport) battery passports — e-bikes, e-scooters, e-cargo bikes — you are looking at 111 mandatory data fields under EU Battery Regulation 2023/1542. That is the most of any battery category. More than EV traction batteries (98 fields). More than industrial batteries (96 fields).
This checklist breaks every field into its source document, the data point you need, and what an acceptable format looks like.
Why LMT batteries have 111 fields
LMT batteries sit at an unusual intersection of consumer product and industrial component. They are sold in high volumes to price-sensitive consumers, yet they involve complex electrochemical supply chains. The 111 fields fall into eight mandatory sections, each with its own data sources and verification requirements.
Section 1: General Battery Information (12 fields)
- Battery ID — Unique identifier following GS1 Digital Link format. Source: your internal product database.
- Battery model — Commercial model name exactly as sold. Source: product catalogue.
- Battery type — Must be declared as LMT. Source: product specification sheet.
- Nominal voltage — In volts, to one decimal place. Source: IEC test report or product datasheet.
- Nominal capacity — In Ah, to two decimal places. Source: IEC 62660-1 test report.
- Energy capacity — In Wh, calculated from voltage x capacity. Source: IEC test report.
- Manufacturer name and address — Legal entity name and registered EU address. Source: company registration documents.
- Manufacturing date — Month and year (YYYY-MM format). Source: batch production records.
- Manufacturing location — Country and city. Source: facility documentation.
- OEM (if applicable) — Both manufacturer and OEM must be listed if different. Source: commercial agreements.
- Battery weight — In kg, to three decimal places. Source: product specification sheet.
- Battery dimensions — Length x width x height in mm. Source: product specification sheet.
Section 2: Carbon Footprint (18 fields)
Carbon footprint is the most data-intensive section and the one most likely to require supplier engagement. It uses a lifecycle assessment (LCA) methodology following EN 50604.
- Carbon footprint declaration — Total kg CO2e per kWh of rated energy capacity. Source: LCA study from an accredited body.
- Carbon footprint per lifecycle stage — Four stages: raw material extraction, manufacturing, use phase, end of life. Source: LCA study broken down by stage.
- Carbon footprint performance class — EU will define classes A-G. Calculated from your footprint against EU thresholds.
- Carbon footprint study reference — Reference number, study date, and accreditation body. Source: LCA study cover page.
The remaining 14 carbon fields cover detailed methodology declarations typically populated by your LCA provider.
Section 3: Materials and Chemistry (22 fields)
This section is where most compliance managers encounter supplier data challenges. Cell chemistry data must come from your cell manufacturer.
- Cell chemistry — Active cathode material (e.g. NMC 811, LFP, NCA). Source: cell manufacturer specification sheet.
- Cathode active material composition — Percentages of Ni, Mn, Co, Li in cathode. Source: cell manufacturer certificate of analysis.
- Anode active material — Graphite, silicon-graphite, or LTO. Source: cell manufacturer spec.
- Electrolyte type — Liquid electrolyte salt and solvent system, or solid-state. Source: cell manufacturer spec.
- Hazardous substance content — All substances above 0.1% w/w on SVHC candidate list. Source: REACH declarations from suppliers.
- Critical raw materials content — Cobalt, lithium, nickel, natural graphite content in grams and percentage. Source: bill of materials and supplier certificates.
Section 4: Recycled Content (8 fields)
From February 2027, LMT batteries must declare recycled content for cobalt, lead, lithium, and nickel. From 2030, minimum recycled content thresholds apply.
- Recycled cobalt content — Percentage from recycled sources. Source: supplier declaration with verification audit trail.
- Recycled lithium content — Percentage from recycled sources. Same requirement.
- Recycled nickel content — Percentage from recycled sources. Same requirement.
- Recycled lead content — Percentage from recycled sources (if lead components are present).
Section 5: Performance and Durability (19 fields)
This section is largely populated from your IEC test reports. If you have current IEC 62660-1 and IEC 62660-2 test reports, most fields are ready.
- Original power capability — Rated maximum continuous discharge power in W. Source: IEC test report.
- Rated capacity — Nominal capacity at rated discharge rate. Source: IEC test report.
- Capacity at 80% rated capacity — Number of full cycles to reach 80% of rated capacity. The primary cycle life metric. Source: IEC 62660-1 cycle life test report.
- Expected battery lifetime — In years and charge-discharge cycles. Source: IEC test data plus manufacturer warranty terms.
- Capacity threshold for end of life — The capacity level as percentage of original that defines end of usable life. Source: manufacturer technical specification.
Sections 6 to 8: Supply Chain, End of Life, and Information Access (32 fields)
Supply chain due diligence (11 fields) requires documentation of your cobalt, lithium, nickel, and natural graphite sourcing — including country of origin and due diligence policy references.
End-of-life information (9 fields) includes dismantling manuals, separate collection instructions, and waste battery collection point information — required in the official EU language of each country where the battery is sold.
Information access (12 fields) covers QR code technical specifications, GS1 Digital Link format, EU registry submission confirmation, and public versus restricted access field declarations.
The five fields most frequently missing at first assessment
- Recycled content percentages — Suppliers do not routinely provide this data. Requires active data collection.
- Carbon footprint per lifecycle stage — LCA studies often provide total footprint but not the EU-required stage breakdown.
- Cathode composition detail — Cell manufacturers treat this as proprietary. Requires a commercial data sharing agreement.
- End-of-life instructions in all required languages — Manufacturers prepare one language and forget the multilingual requirement.
- GS1 Digital Link format compliance — Many manufacturers generate a QR code linking to a webpage, not a GS1-compliant Digital Link URL structure.
How Traceable handles all 111 fields
The Traceable platform has all 111 LMT battery passport fields pre-mapped, validated, and scored. When you upload an IEC test report, AI extracts performance and chemistry data automatically. When you send a supplier portal link, your cell manufacturer fills their section directly. The compliance scoring engine flags any field below 80% completion confidence before you publish.
