Details

Not printed for this model. WattCycle 12V 314Ah Group 4D Dual Purpose Battery: manufacturer product page, Manufacturer product page specification tables prints "Cold Cranking Amps 1800A". Revised on 1 October 2026: WattCycle prints 1800A as cold cranking amps, a battery starting rating, not a locked rotor amperage, so it does not belong in this field.

    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.

Excludes accident, abuse and force majeure; failure to follow the manual; voltage or current mismatch, reverse polarity, wrong fuses or undersized cables; series or parallel connections beyond the permitted limits; mixing with other battery brands; unauthorised disassembly, modification or repair and altered serial numbers; cosmetic wear and natural capacity fade; use beyond the rated cycle life; and damage from more than one year without maintenance charging

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

WattCycle’s Warranty Policy page, captured September 22, 2026, prints "LiFePO4 Batteries All new battery models 5 years 2 years (7 years total)": every new LiFePO4 battery model carries a five-year base term from the original consumer’s purchase date, proved by an order screenshot or invoice. The two further years are conditional and are recorded separately. The policy names no individual model, so the term is read from the category row.

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.

Evidence score

5/10020% 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; Lifetime / capacity 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.
