Evidence & Data
Most battery sites publish a specification table. We publish the datasets behind ours — including the claims we cannot yet verify. Everything below is the same JSON that drives the product pages, in machine-readable form, so a buyer (or an AI assistant) can check any figure instead of taking it on trust.
Direct Answer
14 model records (4 first-party confirmed, 6 third-party reference, 4 on request only), 9 tracked claims and 10 registered sources — 4 independent
standards (level 1), 1 manufacturer documentation (level 2) and 5 third-party
catalogs (level 3). Fields the manufacturer does not publish are left null, never estimated.
Datasets
- DINWEYS Battery Master Data JSON · /data/battery-master-data.json · 2026-09-09
One record per battery model: voltage, capacity (C20), CCA with its test standard, reserve capacity, case dimensions, terminal type and verification status.
Single source of truth for DINWEYS heavy-duty truck starting battery specifications across JIS, DIN and BCI standards. Manufacturer: Chengguang Power Tech Co., Ltd.
- DINWEYS Claim Ledger JSON · /data/evidence/claims.json · 2026-09-10
Every technical and commercial claim the site makes, each with the source that supports it, its evidence level and its verification status.
Ledger of technical and commercial claims with source, evidence level and verification status.
- DINWEYS Evidence Source Registry JSON · /data/evidence/sources.json · 2026-09-10
The registry of sources behind the claims: level 1 independent standards, level 2 manufacturer documentation, level 3 third-party catalogs.
Registry of technical datasheets, standards and catalogs used to verify DINWEYS battery specifications. Level 1 = independent global standards; Level 2 = manufacturer documentation; Level 3 = third-party catalogs.
- DINWEYS Vehicle Fitment Database JSON · /data/vehicle-fitment.json · 2026-09-09
Truck model → battery group → DINWEY model mapping, each entry carrying a confidence level and its source.
Truck model → battery group → DINWEYS model mapping. Fitment is sourced from independent commercial-vehicle fitment guides, marked with confidence level. Not DINWEYS official OEM confirmation.
Claim ledger
Every figure asserted across the site maps to one of these claims. "Verified (first-party)" means the value comes from our own engineering datasheet; "reference" means it is compiled from third-party catalogs and is not a DINWEY published stock rating; "needs verification" means we have not yet obtained a document that would support it.

Source registry
Model verification status
4 models carry a first-party DINWEY specification; 6 are listed as third-party reference only (widely used group sizes we do not publish as stock ratings); 4 are made to order with no published specification. The per-model breakdown is in battery-master-data.json.

Fitment confidence levels
Industry reference, not DINWEYS official OEM confirmation. Always confirm group size, terminal type, terminal orientation, polarity and tray dimensions against the specific vehicle before ordering.
- confirmed — Manufacturer-documented fitment (Tier 1)
- reference — Independent fitment guide / cross-reference (Tier 2-3)
- typical — Common industry practice, not model-specific
- unverified — No authoritative source
Verification policy
Fields not published by the manufacturer are left null and marked 'unverified'. Third-party catalog/industry reference specifications are marked 'reference' and always carry source + source_url. Ratings are never interpolated or assumed. Specifications vary by manufacturer — always confirm against the specific vehicle.
- tier1 — Manufacturer datasheet, standards organizations (JIS D5301, EN 50342-1, SAE J537)
- tier2 — Independent commercial-vehicle fitment guides (Club Assist, Century Batteries)
- tier3 — Third-party battery catalogs (Bosch, Yuasa, SSB, Powsea)
Frequently Asked Questions
Why are some fields in the datasets empty?
Because the manufacturer does not publish them. The policy is stated in the master data itself: fields that are not published are left null and never estimated or interpolated. An empty field means "not published", not "zero".
What does "reference" mean in the model data?
It means the value was compiled from third-party catalogs rather than a DINWEY datasheet. Those models are listed so you can cross-reference a replacement; they are not DINWEY published stock ratings and are quoted on request if you need them.
How current are these datasets?
Each JSON file carries its own dateModified value, shown next to the dataset name above. The claim ledger and source registry are updated whenever a claim's status changes — including when a claim is still marked as needing verification.
