Shipping Policy

Shipping policy

At Sullivan Equipment Co, our goal is to provide transparent and reliable shipping information for our customers. Orders are processed within 24-48 hours upon receipt, excluding weekends and holidays. Orders placed after 5 pm will be processed the next business day. Batteries ship FedEx and will arrive in 5-7 days to most of the US. For shipping quotes to countries outside the United States and Canada, please contact us at support@sullivanequipmentco.com.

Shipping Costs

Shipping costs for Dakota Lithium batteries are calculated per battery due to their classification as hazardous materials (hazmat), ensuring safe and compliant handling and transportation. Shipping costs to Alaska and Hawaii may be higher due to federal law that requires that batteries ship Air Freight and have Hazmat protection. If you need to return a battery, a 10% restocking fee will apply. For details on our return policy, refunds, order edits, and exchanges, please visit our returns page. In case of lost or damaged orders, contact our support team for assistance. Orders may take longer to arrive due to variables outside of our control. We will communicate any potential delays and provide timeline estimates to keep you informed. After placing an order, you will receive a shipment confirmation email with tracking information. For any issues with lost packages, please contact support@sullivanequipmentco.com for assistance. We appreciate your understanding and thank you for choosing Sullivan Equipment Co.
