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.

Introducing the All-New DL+ 12V 320Ah Battery: Bigger, Stronger, More Powerful

Prepare for the toughest conditions with the new DL+ 12V 320Ah battery, the latest in Dakota Lithium’s line of high performance batteries. 

Built for off-grid adventures in your RV, extended ocean voyages, and powerful off-grid systems, this battery is compact, yet packed with 320 Amp Hours of capacity in a water resistant Group 31 size case. 

That’s 6X the usable power of a single Group-31 AGM battery, plus up to 1,000 cold-cranking amps (CCA) for engine-starting power, making it the ultimate single battery solution for boats, RVs, and vehicles requiring both house and starting power.

    Key Features

    • Superior Power: 320 Amp Hours of capacity and 1,000 CCA for reliable power, whether off-grid or starting engines.
    • Compact Design: Fits in a Group-31 size footprint with dimensions of 13.31″L x 7.24″W x 10″H (338mm X 183mm X 254mm), though the wider top L: 15.04″ x W: 7.60″ x H: 9.96 (382mm x 193mm x 253mm) may require checking battery box compatibility.
    • Lithium Iron Phosphate (LiFePO4) Technology: Delivers 6X the power and lasts up to 8 times longer than typical AGM batteries, with a lifespan of 5,000 charge cycles.
    • Durable Construction: Reinforced with a rugged, marine-spec plastic case for enhanced durability, making it ideal for marine, solar, RV, and electric vehicle applications.
    • Water resistant and Built to Last: Designed for extreme environments, offering unmatched performance and an 11-year warranty for long-term value.

    Optimized for: Marine/boating, solar energy, RVs, and electric vehicles.

    For those seeking maximum energy density in a compact, durable design, the DL+ 12V 320Ah is the ultimate power solution. Whether you’re exploring off-grid or sailing the open seas, this battery provides the performance and reliability you need.
