Charged Reviews classified this product from the documents it is based on. It is our own grouping, not a manufacturer claim.
The site's classification of the printed wording "wall or floor mounted" (features) as the "Wall / floor" battery format. This is the catalog's own format grouping, not a manufacturer term; the printed wording is kept in its own field where the catalog has one. Revised on 30 September 2026: The recorded value "wall or floor mounted" was printed text, not one of the site's battery format codes, so the grouping could not read it. It is replaced by the matching code; the printed wording stays in the record history and, where a field exists for it, in that field.

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
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: Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

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.

7 of 20 years, the best documented for a home storage battery (printed by the maker): Bioenno Power 6V 3Ah LiFePO4 Battery (PVC, BLF-0603W)
The North America warranty document prints "seven (7) years from the sales date", extendable to ten years if the customer registers on Dyness's website and obtains Dyness's official approval; use without communications or in RV, camp or marine applications is limited to five years. The dyness.us product page separately prints "10 years full warranty" and "10-Years Warranty" without those conditions; that claim is listed as an alternative with its own source.
7 years unconditional (not scored: 10 years with registration on the Dyness website and Dyness official approval).
