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.

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", and states that refunds apply only to quality issues reported within six months, after which the remedy is replacement. 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. The page fixes no turnaround time for the repair itself and reserves WattCycle’s right of final interpretation.

Summarised from the seven-part exclusion list on WattCycle’s Warranty Policy page captured September 22, 2026. The policy also states that opening a battery at WattCycle support’s direction does not void the warranty, that the warranty applies only to purchases through official WattCycle channels and authorised distributors, and that valid proof of purchase is required. The page carries no effective or revision date and WattCycle reserves the right to revise it.

Printed as "LiFePO4 Batteries All new battery models 5 years 2 years (7 years total)" under the columns Base Warranty and Extended Warranty (with Registration), with the note "Extended warranty must be activated through product registration on the official WattCycle website within 3 months of purchase." The five-year base term applies without registration; the seven-year total needs registration within three months and is kept below as an alternative. Revised on 1 October 2026: The warranty term is the base term that applies without registration. WattCycle's warranty policy prints a five-year base warranty for all new LiFePO4 battery models and a seven-year total only after registration within three months of purchase; the seven-year figure from the product page is kept below as an alternative, and the registration condition is shown in the extended warranty field.
Headline term published on the product page as "Sign Warranty to extend for 7 years". Coverage, eligibility and remedies are set by the WattCycle warranty policy.

The policy prints "LiFePO4 Batteries All new battery models 5 years 2 years (7 years total)" and the note "Extended warranty must be activated through product registration on the official WattCycle website within 3 months of purchase.". The extension is therefore not automatic; a buyer who does not register inside three months keeps the five-year term. Repaired or replaced units do not extend the original period.

I purchased three of these batteries via Amazon (they were shipped direct from Wattcycle) in March 2026. I was able to use the iPhone app to verify all three were up on Bluetooth and showing proper voltage. I installed them in our sailboat as three in parallel in early May and discovered that one of them (Batt03) was not turning on the output MOSFETs. The charge MOSFETs were working properly as I could charge the battery, but the output would not turn on, in spite of the position of the top switch or software setting. I corresponded with Wattcycle about this and they agreed with me that the BMS was likely defective, and they sent me a new one. When I opened the case to install the "new" BMS I made two discoveries: one, the "new" BMS they sent me was actually an older model that would not fit my battery; and two, the actual problem was that the small cable connecting the top switch to the BMS had been caught in the case joint and been damaged. Repairing the cable restored proper operation, so I reassembled the case and installed the battery. We have been cruising the US East coast since then (it is now October '26) and the batteries have mostly been working fine. One problem I noted a couple weeks ago was that one battery was not turning on the output MOSFETs - in spite of the app showing it to be on. I noted a new setting in the app (which recently updated itself) called "Reset System" so I tried this - and everything came back to correct! I looked up the battery on Amazon and it seems they have made a couple changes internally - on my batteries the heavy cable from the BMS to the top M8 terminals is a piece of heavy braid covered with a cloth sheath, while the new ones use a cylindrical stranded wire. The internal metal frame is also slightly different.

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; 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.
5 years · 20% weight
5 of 20 years, the best documented for a home storage battery (printed by the maker): Bioenno Power 6V 3Ah LiFePO4 Battery (PVC, BLF-0603W)
Printed as "LiFePO4 Batteries All new battery models 5 years 2 years (7 years total)" under the columns Base Warranty and Extended Warranty (with Registration), with the note "Extended warranty must be activated through product registration on the official WattCycle website within 3 months of purchase." The five-year base term applies without registration; the seven-year total needs registration within three months and is kept below as an alternative. Revised on 1 October 2026: The warranty term is the base term that applies without registration. WattCycle's warranty policy prints a five-year base warranty for all new LiFePO4 battery models and a seven-year total only after registration within three months of purchase; the seven-year figure from the product page is kept below as an alternative, and the registration condition is shown in the extended warranty field.
5 years unconditional (not scored: 7 years total, only if the buyer registers the product on wattcycle.com within three months of purchase).
