10-Year Solar Battery Warranty

In the unlikely event that your battery ceases to function during normal use, we commit to repairing, rebuilding, or replacing it at no expense within the 10-year warranty period. If you encounter any issues, please reach out to us at Info@RoyerBatteries.com for assistance. Should diagnostics and troubleshooting prove ineffective, we’ll request you to ship or drop off the battery at our Canadian warehouse for repair. While we require the battery to be prepaid for shipping, we will cover the return shipping costs if the battery is found to be faulty. A non-functioning battery, for warranty purposes, is defined as one whose main terminals fail to provide power or accept a charge. This 10-year warranty exclusively covers lithium cells, BMS, and main terminals. All other components fall under our 1-year warranty policy. Warranty denial reasons include, but are not limited to: physical damage, water damage, incorrect BMS parameters, failure to adhere to specified limitations, dead shorting, opening the battery, and attempted repair or modification. In cases where a warranty return reveals misuse, the customer may incur a $150 per hour repair charge, in addition to parts and return shipping costs. Our commitment is to strive for replacements or repairs using identical parts/products; however, if this is not possible, we will supply an equivalent or superior battery. After 5 years, if an equivalent or superior battery is unavailable, a 30% discount off retail can be applied towards the purchase of a new Royer Batteries product. The warranty is provided to the original owner with proof of purchase and is non-transferable.

1-Year Warranty

The 10-year warranty does not extend to auxiliary items on our solar batteries, including USB ports, heating pads, 12v port, Anderson ports, sine wave inverter, MPPT/DC to DC converters, display screen, and communication ports. All items not covered by the 10-year warranty come with a one-year warranty against defects. We stand behind our products, offering assistance with any issues during or after the warranty period. The 10-year warranty exclusively applies to our solar batteries and excludes other products or services. Our services and other products are guaranteed to be defect-free for 1 year unless stated otherwise.

Solar Battery Lifetime

Our warranty policy aims to shield customers from defects preventing the battery from delivering power. We assure all customers that our products will continue to generate power well beyond the 10-year warranty period. Utilizing LiFePO4 prismatic cell chemistry, our batteries boast a cycle life of up to 3000 – 5000 cycles (minimum to ideal usage) until 80% capacity remains. Consequently, you can anticipate approximately 80% capacity after 8-13 years of daily cycling. With half a cycle per day, this extends to 16-26 years. Under proper storage, use, and care, these batteries can last up to 25 years while maintaining useful energy capacities. Opting for a battery with excess capacity can further extend its lifetime through efficiencies and lower capacity requirements.
