5/16"-18 Thread Female Lead Battery Terminal Post Adapter Battery Terminal Charging Posts for 5/16"-18 Stud Extension, Pack of 2

This adapter is made of lead. The supplier capitalises the word in its opening line, and it is worth saying at the top here because the search summary above describes the part as a lead take-off, a phrase that reads as a cable connection rather than as the metal the thing is cut from.

The thread it is cut for

Sizing decides everything else. The thread is SAE 5/16 inch-18 and it is female, so the adapter drops over a stud cut to that same designation and does up onto it. Your battery has to be carrying that stud already; there is no adjustment in the part and no second size in the packet. For chemistry the supplier lists lithium as well as lead-acid, and the finished job is a standard tapered top post where a bare stud used to be.

Handling guidance is absent from this listing

The supplier's description carries no handling advice, no storage note, no cleaning instruction and no cautionary line of any kind. That is a statement about the listing rather than about the metal: we are pointing at what the page omits, rather than filling the gap with wording the manufacturer never issued. If that guidance matters to you, and it reasonably may, ask the seller for the manufacturer's own text before you commit to the part.

Points this page does not settle

• The metal is lead and the description prints no handling, storage or disposal guidance to go with it.
• The search summary above uses the phrase lead take-off, which a reader can easily take as an electrical lead. The material is the metal.
• Neither a current rating nor a voltage rating is printed anywhere here, though the part sits in the battery path and carries its current.
• No torque figure is offered for the threaded joint. Hand tight is the whole of the supplier's instruction.
• No overall height is given, no spanner size across the flats, and no weight, so judging clearance above the terminal from what is printed is not possible.

A 5/16 inch-18 stud, a female thread and lead as the metal: those are the three facts to check this against before anything else on the page.
