This is custom made by a car lover, full copper car battery terminals. Then he offer this opportunity to others with group buy basis. Here I'm just share some info about copper that I'm able to get from Internet, mainly wikipedia EN & TW.

Car battery terminal got 2 standard size. Which is regular and small. Just refer to the picture for detail.

You may get from car battery manufacturer website as well.

Most familiar conductors are metallic. Copper is the most common material used for electrical wiring. Silver is the best conductor, but it is expensive. Because gold does not corrode, it is used for high-quality surface-to-surface contacts. However, there are also many non-metallic conductors, including graphite, solutions of salts, and all plasmas. There are even conductive polymers.

BTW, Aluminum is not as good a conductor, but it is MUCH cheaper. This is why power utilities use aluminum for most 'everyday' applications in their systems.

Properties of Copper

• An excellent electrical conductor	• tough
• An excellent thermal conductor	• non-magnetic
• corrosion resistant	• an attractive colour
• anti-bacterial	• easy to alloy
• easily joined	• recyclable
• ductile	• catalytic

Electrical conductivity

Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance.

銅的特性 純銅是一種堅韌、柔軟、富有延展性的紫紅色而有光澤的金屬，1克的銅可以拉成3000米長的細絲，或壓成10多平方米幾乎透明的銅箔。純銅的導電性和導熱性很高，僅次於銀，但比銀要便宜得多。銅的顏色很像金，但發紅，銅離子的顏色為藍色。有劇毒，不過，用特定加工法加工的銅沒有毒。銅在乾燥空氣中安定，可保持金屬光澤。但在潮溼空氣中，表面會生成一層銅綠（鹼式碳酸銅[1]），保護內層的銅不再被氧化 銅的應用 銅具有極佳的導電性，這個特性使它被大量用於電氣工業，以單位體積來說，銅的導電性僅次於銀，用來做為導線和電子電訊器材的電器零件；銅的高導熱性也僅次於銀，如電冰箱、蒸發器、加熱線圈等皆利用其導熱性；另一個重要的性質為抗腐蝕性，銅管用於運送自來水時管壁內不會沉積礦物質，可改善鐵管之缺點，所以高級衛浴設備中的給水物件多使用銅，同時也用於冷卻裝置、太陽能設備和空調系統；另外也大量用於建築業和汽車業。 銅的最普遍用途在於製造電線，通常現時所用的電線都是由純銅製成，這是因為它的導電性和導熱性都僅次於銀，但卻比銀便宜得多。而銅可用於製造多種合金。 下列是常見金屬的導電率，依高低順序排列： 銀 6.3×107 (商用純銀) 銅 5.85×107 (純銅) 金 4.25×107 　 鋁 3.5×107 (高純度) 鋁 2.31×107 (＋1% Mn) 鎢 1.82×107 　 黃銅 1.56×107 　 鐵 1.07×107 　 白金 0.94×107 　 鋼 0.7×107 　 不銹鋼 0.14×107 　 註：由於銀是導電率最高的導体，是故導電率係以銀為 1：其他金屬比較： Rate=M1 Cond./Silver Cond. 如以銅的導電率為100%，那銀與金的導電率分別是，銀的導電率為113%，金的導電率為83% Interested?
