    Manufacturer-operated product page captured byte for byte. This page was already recorded as a source for this exact catalog row, so no page was discovered by guessing a URL and no product was matched by name. It establishes what BigBattery published there on the access date: the specification rows printed on the page, the documents linked from it and the image it presents. Marketing copy and any standards named on the page remain manufacturer claims that no issuer or laboratory record was read against.

    Manufacturer-operated product page, captured byte for byte with a plain HTTPS GET and a desktop user agent. It establishes what the manufacturer published at this URL on the access date for this exact model: the specification table it shows, the page photo and the documents it links. Values rendered only by client-side scripts are not part of the capture. Marketing text, certification wording and stock state remain manufacturer claims that were not independently verified, and nothing on it was applied to any other model.

Evidence score

12/100Missing details20% documented

The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.

Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.

Missing for this product: Certificates evidence needed; Warranty energy disclosure evidence needed; Lifetime / capacity evidence needed; Cell model disclosure evidence needed.

72 V · Format not recorded · Rated capacity

The warranty term and the lifetime energy are each scored against the best documented value for a home storage battery: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
