A: Standard shipping takes 5-10 business days, express shipping takes 2-5 business days. Processing time is 1-3 business days before shipment. Due to hazardous materials regulations for lithium batteries, certain shipping methods and destinations may be restricted. See our Shipping Policy for full details.
Q: Do you ship to all US states?
A: We ship within the contiguous United States. Lithium batteries are classified as hazardous materials, which may limit shipping options to Alaska, Hawaii, and certain remote areas. If your location cannot be served, we will contact you before processing your order.

Warranty
Q: What warranty comes with my battery?
A: All Kingboss LiFePO4 batteries include a 1-year warranty covering defects in materials and workmanship under normal use. The warranty includes free repair or replacement of the defective unit. See our Warranty Policy for full terms and coverage details.
Q: How long will the battery actually last?
A: Our LiFePO4 batteries are engineered for a design lifespan of 5 to 10 years, depending on usage patterns and depth of discharge. With proper care, many users enjoy reliable performance for well over a decade. The 1-year warranty covers you against early manufacturing defects, while the LiFePO4 chemistry ensures the battery outlasts lead-acid alternatives many times over.
Q: What does the warranty not cover?
A: The warranty does not cover damage caused by improper installation, incorrect charging equipment, physical abuse, or use outside the specified operating conditions. Please review the product manual for proper usage guidelines.
Product & Compatibility
Q: Will this battery fit my RV or boat?
A: Our 12.8V 100Ah batteries use the Group 31 form factor, which fits most standard RV and marine battery trays. Please check your existing battery compartment dimensions against the product specifications listed on each product page.
Q: What charger do I need?
A: We recommend using a charger with a dedicated LiFePO4 charging profile (14.2V to 14.6V). Most modern RV converters, marine chargers, and solar charge controllers have a lithium setting. Using a lead-acid charger is not recommended and may reduce battery performance.
Q: Can I connect multiple batteries together?
A: Yes. Our batteries support up to 4 in series and 4 in parallel. Always use identical batteries with the same capacity and age. See the product manual for detailed configuration instructions.
