ExpertPower Terms & Conditions

Return Policy

We are committed to ensuring your satisfaction with your battery purchase. If you are not completely satisfied, you may return the product for a refund within 90 days. For products purchased directly from an authorized dealer, their return policy applies. Please contact them directly for more information.

ExpertPower can only accept returns on products that are within warranty and sold by ExpertPower Direct. Return labels are provided for up to 90 days after the initial delivery, in cases where the product is covered under the manufacturer's warranty (e.g., defective/quality-related) or if a wrong product was sent.

If the return is not quality-related and falls within the 90-day period, the customer is responsible for the return shipping costs and may be subject to a restocking fee of up to 20%. All returns after the 90-day window must be returned by the customer. For packages exceeding $100 in value, it is recommended to purchase insurance coverage to safeguard against potential loss. We are not obligated to issue a refund or replacement without receiving the returned item.

Restocking fees apply in the following scenarios:

  • • Refund requested after testing confirms non-defective items.
  • • Wrong item ordered by the customer.
  • • Item no longer needed by the customer.

We will not accept returns if the wrong product is sent to us. This return policy applies to all selling channels, including Amazon, Walmart, Home Depot, and others.

    1-Year Limited Warranty

    All ExpertPower batteries (except LiFePO4 batteries) come with a 1-Year Limited Warranty against defects in material and workmanship. This warranty applies only to the original owner and becomes void if the product is used commercially, structurally altered, subjected to excessive stress beyond the physical limits of the materials used, or damaged due to abnormal use. Punctures and normal wear and tear are not covered. For limited edition or out-of-stock products still under warranty, ExpertPower will replace them with an equivalent value product in a different color, based on availability.

    LiFePO4 Warranty and Return Information

    All ExpertPower LiFePO4 batteries are covered by a 2-Year Warranty from ExpertPower (except the PRO Series and EP48100). For more details on the LiFePO4 Battery warranty, please refer to the Warranty Info section.

    Warranty Disclaimer

    This warranty does not cover any incidental or consequential damages resulting from the use of the battery. If the warranty applies, the manufacturer will repair or replace, at their discretion, the battery or any defective part or component.

    ExpertPower reserves the right to make changes to products and designs without incurring any obligations to incorporate those changes into previously completed products. Our policy is to honor product warranties and perform services only on products purchased from ExpertPower or an authorized ExpertPower reseller, accompanied by a receipt or proof of purchase.

    The warranty will not be valid for purchases made from unauthorized resellers, distributors, or drop-shippers.

    Please be aware that there are websites and dealers claiming to be authorized ExpertPower resellers when they are not. Products sold on such websites do not carry a warranty from ExpertPower. Purchasing products from unauthorized websites carries risks, including the possibility of counterfeit, used, or defective products.


    Installation Disclaimer

    ExpertPower highly recommends that all solar kits be installed by a licensed and qualified professional. Installation of solar kits involves working with electricity, which can be dangerous if not handled properly. Improper installation may lead to electric shock, fire, property damage, or personal injury.

    By purchasing and using our solar kits, you acknowledge and agree that you are solely responsible for the proper installation, operation, and maintenance of the system. ExpertPower disclaims any liability for damages or injuries resulting from the installation or use of our solar kits by non-trained individuals.

    • Electrical Expertise: Solar kit installation involves electrical connections. We strongly advise against installation by individuals who are not licensed professionals.
    • Safety Precautions: Follow all safety guidelines and local electrical codes, including proper grounding and wire sizing.
    • Compliance: It is your responsibility to ensure the installation complies with all applicable local, state, and national laws.
    • Product Warranty: Our warranty does not cover damages resulting from improper installation, modification, or unauthorized repair.

    By proceeding, you confirm that you have read and understood the risks involved and agree to assume full responsibility for the installation process.
