   MOQ refers to the smallest number of units a supplier is willing to sell. Understanding MOQ is critical for budget-conscious buyers, as it affects inventory levels and cash flow. Negotiating favorable MOQs can lead to better pricing and reduced financial risk.

3. RFQ (Request for Quotation)
   An RFQ is a document sent to suppliers requesting pricing information for specific products or services. For B2B buyers, issuing an RFQ can streamline procurement processes and ensure competitive pricing. It’s essential to include detailed specifications to receive accurate quotes.

4. Incoterms
   International Commercial Terms (Incoterms) define the responsibilities of buyers and sellers in international trade. Familiarity with terms such as FOB (Free on Board) or CIF (Cost, Insurance, and Freight) is vital for understanding shipping responsibilities and costs. Properly negotiating Incoterms can significantly impact the total landed cost of solar batteries.

5. Warranty
   A warranty outlines the terms under which a manufacturer will repair or replace defective products. Understanding warranty terms is crucial for B2B buyers, as they can influence the long-term viability of an investment. Buyers should look for comprehensive warranties that cover both performance and defects.

6. Lead Time
   Lead time refers to the time between placing an order and receiving the products. Knowing the lead time is essential for project planning and scheduling. Buyers should account for lead times when negotiating delivery terms to ensure timely project completion.

By mastering these technical specifications and trade terminologies, B2B buyers can navigate the solar battery market more effectively, ensuring they select the best solutions for their needs and those of their customers.
