Read the battery type, model, capacity, and terminal layout from the label, and photograph that label on the actual stock. Do not infer chemistry or performance from size or a similar-looking unit. State whether the battery is new, used, or tested and explain what any test covered.

Keep terminals protected and follow the maker's storage directions. Separate damaged, leaking, or swollen units from saleable stock. If a core return or exchange is part of the offer, state the amount, condition, timing, and handling terms separately before accepting the order.

Check the carrier's current restrictions for the exact battery type and route. Avoid promising starting performance from a printed rating or a visual check. Retain supplier information with the batch and update the listing if the specification or included exchange terms change.
