These battery terminal post adapters convert JIS (pencil posts) battery terminals to SAE (standard posts). Our adapters are made from high quality lead for optimal terminal contact and power transfer. 
 
The price is for a set of two, one positive and one negative. The larger is for the positive terminal, while the smaller is for the negative.
 
To fit, simply place the adapters over their corresponding posts and push down until flush with the top of the battery terminal posts.
