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.

Location: Warranty Policy page, section III "Warranty Exclusions (Limitations of Liability)"

WattCycle’s Warranty Policy page, captured September 22, 2026, prints "Accessories Chargers, inverters, controllers, wiring cables , etc. 1 year". A wiring cable 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.
