The 16-page user manual LiTime serves under the User Manual tab of its own product page for L12V40A-DC-E, fetched from LiTime's Shopify file store on September 22, 2026 and archived here byte for byte with its SHA-256. It establishes that LiTime published this document for this product on the access date, and it is attached to the record so a reader can check the installation, wiring, charging and safety instructions against the catalog. Every recorded value comes from the product page instead. The manual carries no revision number and no revision date, so a later edition served from the same URL would be indistinguishable except by its hash. Nothing in it was read as a certification, a warranty commitment or a test report.

LiTime's published Warranty Policy page, linked from the footer of every page on litime.com and captured byte for byte on September 22, 2026. It establishes the terms LiTime published on the access date: a limited warranty against defects in workmanship and material under normal consumer use; a Warranty Period table that gives new batteries five years by voltage class and minimum capacity (12V from 20Ah, 16V from 30Ah, 24V from 25Ah, 36V from 50Ah, 48V at any capacity, 51.2V from 30Ah), charge controllers three years, AC-DC and DC-DC chargers two years, 12V 1000W/2000W/3000W inverters two years, and monitors, busbars, switches, circuit breakers and battery boxes one year; a shorter table for Like New product; repair at LiTime's expense or a free equivalent replacement with a further 90-day repair warranty; a term that starts at installation or receipt by the original consumer purchaser and needs a receipt; and the exclusions. It states plainly that the warranty is limited to the original consumer purchaser and is not transferable. It is a web page, not a signed warranty contract: it carries no revision date or version, names no per-SKU term, and establishes no claim outcome. Where a product page prints a term for a model the policy table's capacity floor would exclude, the page figure is recorded and the conflict is written into that product's identity note.

LiTime's own product page at litime.com/products/12v-40a-dc-to-dc-battery-charger, captured on September 25, 2026 for the completeness pass. It establishes what LiTime printed on that date: the product heading, the variant part numbers (L12V40A-DC-E), the description and the Specs tab. Figures read from it are LiTime's own claims; the page prints no test conditions, certificate numbers or revision date. Prices and stock on it are not recorded.

Manufacturer-operated product page for L12V40A-DC-E (LiTime 12V 40A DC to DC Battery Charger), captured byte for byte on September 22, 2026 during a crawl of every one of the 244 products LiTime lists at litime.com/collections/all/products.json. It establishes what LiTime published on the access date and nothing more: the product title, the variants and their SKUs and prices, the marketing description, the specification table under the Specs tab (BASIC, DIMENSIONS, TEMPERATURE sections), the documents offered under the User Manual tab (LiTime12V_40A_DC-DC_Chargers_-_User_Manual.pdf) and the photographs the page publishes. It is a retail page, not a datasheet: LiTime publishes no test conditions, no cell maker, no certificate numbers and no revision date for it, and where it disagrees with a value the catalog already records the disagreement is written into the product identity note rather than resolved. Prices and stock shown on it are the September 22 state of a promotional page and are not recorded as facts.

Summarised from the three numbered exclusions printed on LiTime's Warranty Policy page captured on September 22, 2026. The page prints no wear-out, capacity-retention or cycle-count exclusion and no energy-throughput limit, so a capacity complaint is not addressed by the published text.
