AT / ASSEMBLY ITEMS (Custom Built-to-Order Packs)

Our normal return/refund policy does not apply for AT/Assembly Items. All items marked “AT” or “Assembly Items” are built to order, and have a lead time of 3-7 business days. Expedited shipping does not affect the lead time. Any cancellation or return request for made-to-order items will be subjected to a 30% restocking fee. Most of the fee is for the labor/costs to create the custom (built-to-order) battery pack. We still have have 90-Day Warranty on custom battery packs; any returns due to a defect will be heavily evaluating to make sure the battery pack, and not the customer's devices, are performing within the specs noted on our listings.
