多加了很多二极管，增加能耗。电池要换得比以前更勤快了。懒人是很浪费社会资源的。

If I read it correctly, it is simply putting different contacts at both ends and doesn't contain any circuit.

That's not what it said. It said "appears to work simply enough,including both positive and negative contacts at both ends.". It may contain other parts which are unkown at this moment.

That's exactly what it said. Positive contact is smaller and positioned in center while negative contact is larger and positioned at outside. They are present and positioned same at both end to allow batteries to be installed freely.

No. It doesn't say it doesn't contain any circuit.

在北美开车是必须的，象这样的电池夹就显得多余。如果你现在连这都还没搞明白，那就是属于蠢的那一类。

Is it a bit narrow mind to make such as call? It can be very useful for certain situations, such as replace the battery quicker in the dark (for example, the National Geographic photographers)

高档照相机都不用干电池，都是用整块锂电池。，锂电池电容量远远大于干电池，更换一块锂电池的速度比一节一节地换干电池快不知快多少倍呢。

个人觉得高档相机用特制的锂电池是为了多挣钱。要是能用AA电池省钱不是一点。AA也有锂电池，还有可以重复充电的镍金属和锂离子电池。四节AA不比很多差不都大小的锂电池差呀。

买高档相机的人都不在乎这些小钱，他们图的是方便。

干电池和锂电池的体积大小充电量放电率性价比是不可同日而语的。

story time. 故事一，世界上诞生第一辆汽车时，一个人看后，笨重，冒黑烟，巨响，蠢，驾着豪华马车走了；故事二，未来，人类进步博物馆，孩子看展品，起初人们使用的电池非常简陋，使用者必须颠过来倒过去...；微笑，我们有了汽车，和方便使用的电池。尊重创新

Some Americans are becoming smarter and smarter, in the meanwhile, some others are being spoiled and are becoming less and less intelligent. lol

有价值的创新才有意义。汽车解决了交通问题，使得普通人能够到达自己以前到不了的地方。汽车的出现扩展了个人所能触及的空间。 这个电池夹只是为了解决某些人不懂什么是电池的正负极 的问题。 试想一下，有什么产品电子需要如此频繁地更换电池，而且使用者又是连正负极都不愿了解一下人。
