WattCycle’s Warranty Policy page, linked from the footer of every page on www.wattcycle.com and captured byte for byte on September 22, 2026. It establishes the terms WattCycle published on the access date: a warranty-period table that gives all new LiFePO4 battery models a five-year base term plus two further years (seven total) on registration within three months of purchase, gives like-new units one year, gives battery cells no warranty at all, and puts chargers, inverters, controllers and wiring cables together in an "Accessories" row with a one-year term; the claim process and its 24-48 hour response promise; a fee table under which WattCycle pays shipping for a confirmed quality defect and the buyer pays it for a change of mind; a refund window of six months; and an exclusion list. It names no individual model, carries no effective or revision date, and reserves WattCycle’s "right of final interpretation", so it fixes no claim outcome and cannot be read as a warranty contract for any one product.

Retrieved
Manufacturer-operated product page for WattCycle’s shunt battery monitor, captured byte for byte on September 22, 2026. It establishes only what WattCycle published on the access date: the product name, which states the shunt rating, and the price. Its "Tech Specs" tab is empty, it links no manual and it offers no downloads, so the page publishes no display size, no voltage range, no measurement accuracy, no communication interface and no dimensions. It is also the page that shows this product’s naming to be unsettled: the title and the site navigation say 500A, while the ordering code is WTMONITOR350AA and the product photographs are filed under names ending 350A. Nothing on the page resolves that.
The policy prints "Quality issue (within 6 months) Free replacement/refund WattCycle covers shipping costs" and "Quality issue (after 6 months, within warranty) Free replacement WattCycle covers shipping costs". A claim starts by e-mailing service@wattcycle.com with proof of purchase; WattCycle promises a reply in 24 to 48 hours and then issues an RMA number. No turnaround time for the repair itself is fixed, and WattCycle reserves the right of final interpretation.

Summarised from the seven-part exclusion list on WattCycle’s Warranty Policy page captured September 22, 2026, which is written as one list covering every product category rather than per product. The page carries no effective or revision date, applies only to purchases through official WattCycle channels and authorised distributors, and requires valid proof of purchase.

Documented
WattCycle’s Warranty Policy page, captured September 22, 2026, prints "Accessories Chargers, inverters, controllers, wiring cables , etc. 1 year". A battery monitor therefore carries one year from the original consumer’s purchase date and no registration extension: the two further years in the table belong only to the "LiFePO4 Batteries" row. The policy names no individual model, so the term is read from the category row.
