Data and assistant tools

Every page on this site is generated from the records below. The same JSON is served here, unchanged, so an assistant or a spreadsheet can read exactly what the pages read. The generated field is the build date; every record carries its own checked dates, and a build date is not a verification date.

• Batteries: 19 records. Capacity as an array of rated points, cycle life at a stated depth of discharge, charge limits, NCC listing with list version date.
• Appliances: 28 records. Published consumption figures, sizing basis, interlocks and blocking notices.
• Mains chargers: 16 records. Profiles per chemistry, lithium profile present or absent, selection method.
• DC-DC chargers: 6 records. Output, input window, trigger, smart-alternator and lithium statements, link to the maker’s cable and fuse table.
• Split charge relays: 6 records.
• Base vehicles: 16 records. What the vehicle maker publishes about alternator charging behaviour, or the absence line.
• Rules: 30 records. The claims ledger: every number a checker applies, with evidence grade, source, clause and jurisdiction, including rules recorded as not implemented.
• Merchants: programme status for every retailer linked.
• Checker dataset: the single file the browser checkers fetch.

Across the product collections there are 175 recorded absences, each with the document that was checked and the date.

Field meanings

sources[]

One entry per field group. evidence is the grade (standard, manufacturer, scheme, convention, secondary, unverified). quote is verbatim. checked is the date the document was read. hosted_by: distributor flags a maker’s document read on a distributor server.

sources[].absent

True when the document was checked and does not state the field. Rendered as “No published [figure] found (checked [date])”. Never a negative claim.

gaps[]

The field groups the maker does not publish. Each has a matching absent source entry.

capacity_ratings[]

Every rate the maker publishes. rate: unstated means the maker gives a number with no rate; do not assume C20.

cycle_life[]

Only recorded with dod_pct and eol_criterion. A cycle count without both is not a fact.

dod_guidance

The maker’s own depth-of-discharge guidance. published: false renders the absence line.

ncc.list_version_date

Which NCC list a figure came from. The March 2024 list dropped the capacity and cycle columns. rate_basis_published is always false: the scheme does not state the discharge rate.

sizing.basis

How the checker uses an appliance figure: published average, Ah/h at a stated ambient, Ah per 24 h, published range, rated upper bound, reader-entered, or inverter.

sizing.interlock / blocking_notice

Text the checker must show; an interlock excludes a figure from the total, a blocking notice is shown before any number.

lithium_profile

published, absent (renders the absence line) or published_but_unspecified.

rules: implemented

False for rules recorded as unverified or convention-only that the checker refuses to apply; not_implemented_reason says why.

retailers[].affiliate

False until a programme has approved the live site. Tags never appear in the data.

Browser tools (WebMCP)

Where the browser supports it, four read-only tools are registered on the checker pages: size_leisure_battery, charging_method, list_products (paged envelope with schema_version: "2.0", total, returned, offset, limit, has_more, next_offset, records, disclaimer) and glossary_lookup. Numeric inputs are clamped and enums revalidated. Tool outputs never repeat the numbers a user entered. There is no cable-sizing tool.
