At Fleet Lithium, we build our products for demanding, real-world applications—and we stand behind them. Our warranty program is designed to protect your investment and give you confidence long after your purchase.

Warranty coverage varies by product category, with full-replacement coverage during the initial warranty period followed by prorated coverage on eligible products. Our support team is also available to help diagnose problems, answer technical questions, and guide you through the warranty process if an issue arises.

Warranty Coverage by Product Category

What the Warranty Covers

Fleet Lithium's warranty is intended to protect against qualifying defects in materials and workmanship when the product is installed, operated, charged, stored, and maintained in accordance with Fleet Lithium's requirements.

Coverage is subject to the terms applicable to the specific product and warranty period.

Warranty Exclusions

Warranty coverage does not apply to damage or failure resulting from circumstances outside normal covered product use, including:

  • Misuse, abuse, neglect, accident, or physical damage.
  • Improper installation, wiring, charging, maintenance, or storage.
  • Unauthorized modification, disassembly, alteration, or repair.
  • Use of the product outside its intended application or operating requirements.
  • Damage caused by incompatible equipment or components.
  • Normal cosmetic wear or other conditions that do not affect the covered operation of the product.

Additional exclusions and requirements may apply. Please review the complete Fleet Lithium warranty terms for full details.

Transferable Warranty

Eligible Fleet Lithium warranties may be transferred to a subsequent owner, helping preserve the value of your investment if the vehicle, vessel, equipment, or battery is later sold.

To request a warranty transfer:

  1. Provide the new owner's contact information.
  2. Provide proof of the original qualifying purchase.
  3. Contact Fleet Lithium Support so the warranty record can be updated.

Transfer requests can be submitted through our Contact Page.

Real Support From Fleet Lithium

A warranty is only valuable if there is someone available to help when you need it. Fleet Lithium provides product and technical support for warranty questions, troubleshooting, installation concerns, and product diagnostics.

Why Fleet Lithium's Warranty Matters

  • Long-Term Coverage: Multi-year protection on eligible Fleet Lithium battery products.
  • Full-Replacement Protection: Eligible products receive full-replacement coverage during the initial warranty period.
  • Continued Prorated Protection: Coverage continues beyond the full-replacement period on qualifying products.
  • Technical Support: Our team can help diagnose an issue before assuming that a battery needs to be replaced.
  • Transferable Coverage: Eligible warranties can remain with the product when ownership changes.
  • Clear Claim Process: We guide customers through diagnosis, documentation, and resolution from start to finish.

We're Here for the Long Haul

We understand that a Fleet Lithium battery is an investment in your vehicle, equipment, vessel, or energy system. Our goal is not simply to sell you a battery—it is to provide a product you can depend on and the support to stand behind it throughout its service life.

If you ever have a question about your product, its installation, operation, or warranty coverage, contact Fleet Lithium. We would rather help you diagnose a concern early than leave you wondering what to do next.
