10-Year Solar Battery Warranty
In the rare case that our battery stops working through normal use, we will repair/rebuild/replace your current battery at no cost if it’s within the 10-year warranty period. If there is an issue with your battery, please email us at firstname.lastname@example.org to get help. If after diagnostics and troubleshooting the battery still does not work, we will ask you to ship or drop off to our Canadian warehouse for repair. We require the battery to be prepaid shipped and we will pay to ship back to you if the battery is deemed faulty. For a battery to be considered not working, the main terminals will not provide power/take charge. This 10-year warranty covers the lithium cells, BMS and main terminals only. All other items and parts are covered under our 1-year warranty policy. Reasons for warranty to be denied include but are not limited to: physical damage, water damage, setting incorrect BMS parameters, not following specified limitations, dead shorting, opening the battery, and/or attempting repair or modification. If it is determined that the battery was sent back for warranty and the battery was misused in any way, the customer will be subject to a $150 an hour repair charge plus parts and return shipping costs. We will always try to replace and repair with the same parts/products but if we cannot, we will provide an equivalent or better battery. After 5 years, if an equivalent or better battery is not available, a 30% discount off retail can be granted towards the purchase of a brand new Royer Batteries product. Warranty is provided to original owner with proof of purchase and is non-transferable.
The 10-year warranty does not extend to all auxiliary items on our solar batteries including but not limited to: USB ports, heating pads, 12v port, Anderson ports, sine wave inverter, MPPT/DC to DC converters, display screen, communication ports. All items on a battery that fall outside the 10-year warranty come with a one-year warranty free of defect. We do stand behind our products and if we can help we will. Reach out for help, parts or issues during or after warranty. The 10-year warranty only applies to our solar batteries and does not include any other products or services. Our services and other products are guaranteed for 1 year defect free unless otherwise stated.
Solar Battery Lifetime
Our warranty policy is intended to provide customers with protection against any defects causing the battery to not provide power. We want all customers to be assured that our products will be outputting power far beyond 10-year warranty. With the LiFePO4 prismatic cell chemistry we use in our batteries, the cycle life is rated for up to 3000 – 5000 cycles (minimum to ideal usage) until 80% capacity is left. Therefore, you can expect around 80% capacity left after 8-13 years of daily cycling. If you use half a cycle per day, this extends to 16-26 years. These batteries (with proper storage, use, and care) can last up to 25 years while still having useful energy capacities. If you buy a battery with more capacity than required, lifetime can be further increased through efficiencies and lower capacities requirements.
