What to name in your inquiry
Name the camera kind and the battery type: mirrorless, DSLR, broadcast, or another kind, and the type within the battery line — rechargeable, lithium, digital, V mount, or another type. Name the quantity you have in mind, and the market you sell into. An inquiry that names the camera kind and the battery type will receive a specific answer; an inquiry that names only the word battery will receive a general answer.
Name the use as well: how long a shoot lasts, and in what conditions. A battery for a short indoor session and a battery for a full day outdoors are different needs, and the supplier's answer should reflect the need you actually have. The battery types guide explains the types, and the pairing guide explains how batteries and chargers work together.
Four confirmations, before payment
First, the minimum order quantity for your order: what quantity the supplier requires, and whether it differs by type. Second, the lead time, with its meaning: whether it counts from order, from payment, or from production start, and what happens if it slips. Third, the specification for the exact type: the document that describes what you will receive, so the goods can be checked against it on arrival.
Fourth, the certificates that apply to your market, by name, with documents attached. Certificates are available upon request; the inquiry is where you name your market and ask for the documents that apply to it. A supplier who answers all four in writing, with documents, is a supplier whose order can proceed.
Before payment, confirm the minimum order quantity and lead time for your order. Certificates are available upon request.
What not to assume
Do not assume that a battery that fits one camera kind fits another, that a capacity figure describes a battery fully, or that a general assurance covers your market's certificate needs. Each assumption is a common cause of a wrong order, and each is avoided by naming the camera kind, the type, and the market in the inquiry. The inquiry process page explains the sequence in full.
