    Retrieved

    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.

Warranty

Remedy
Free replacement or refund for a quality defect confirmed within six months of purchase, free replacement for one confirmed after six months and inside the term; WattCycle pays shipping both ways in either case, after an RMA number is issued
Official warrantyPaid link.
Sources

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.

Sources

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.

7 years

Sources

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.

Cheap homemade solar generator

No major issues so far. Purchased from Amazon Sept 2025 for $170+tax. I did discharge to the 0% cutoff accidentally and didn't attempt charging for a few weeks. The 10A charger I was using wouldn't wake it up, but I connected it to a larger 12v battery (Dumfume 300ah), and that woke it up enough for the 10A charger to start working on it. No issues since then I found a plastic tote that fits it well, with some space for bus bar and cables, and have it connected to a 2000w Jupiter (Modified Sine Wave inverter from Harbor Freight) and a USB-A/USB-C/12v Aux module. I use it mainly to charge mobile devices when off grid, or for a diesel heater, and only use the inverter when there is low risk of damaging a device (like when it has an AC to DC converter box inline, or it's a simple device with a resistive heater (cheap rice cooker)). I look forward to using it more, so far no obvious degradation, though I've never done testing to confirm capacity or cutoffs.

For now seems to work fine and well in combination with Victron smartsolar and shunt in my small solar boat powering a 12v 660W Amarew 66lbs trolling motor.

Disclosure: I work in the renewables sector as advisor, but this is a private purchase for my solar boat

It has behaved as expected so far with no issues. Communication with the seller was efficient. Purchase was in August, 2025. I can't comment on long term reliability.

Delivery: On time

I had ordered the battery on Amazon, with returns shows as not available. When I found it cheaper at WattCyle they efficiently canceled the Amazon order for me.

Evidence score

12/10040% documented

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 for this product: Certificates evidence needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.

12 V · Case battery · Rated capacity

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.

Warranty term5 years5 / 20

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).

25 / 100 × 20 = 5 points.

Lifetime / capacity5,000 cycles6.67 / 20

5 MWh/kWh · 20% weight

5 MWh/kWh is our own estimate, so it is capped at one third of the criterion: it is scored against the bar but never sets or raises it. The bar is 7.638 MWh/kWh, the best documented for a home storage battery lifetime claim, calculated from maker figures: EG4 WallMount All Weather 314Ah

Estimated: 6.4 MWh ÷ 1.28 nominal kWh. Operating conditions still apply.

33.33 / 100 × 20 = 6.67 points.

Our own estimate from cycles and depth of discharge: it is scored against the best documented figure but earns at most one third of this criterion. A figure the maker prints is scored in full.

WattCycle's 12V Series LiFePO4 Battery User Manual (V1.9, dated 2026.03.02 in its file name, archived by the catalog and refetched byte-identical on September 25, 2026) prints a shared specification table for the models it lists, including "12V 100Ah", with the row "Cell Certifications UL1642/UL2580/UN38.3". The claim is for the cells, not the battery pack. WattCycle publishes no certificate number, certification body or report for it, and no issuer listing was checked. Recorded exactly as the manual prints it.
