关于蓄电池正负极的识别

一般常用的蓄电瓶在生产设计时．其电瓶桩较粗些的一端为正电极．另一端则细些为负电极，同时可辨认一下电瓶桩柱的颜色，其中正电极桩柱呈现深棕色，而负电极则呈现为深灰色。另外有些电瓶的正负标记用英文字母表示，即P表示为正电极，N表示为负电极，这在检修充电时可千万不能搞错。

In the production design of commonly used electric storage batteries, the thicker end of the battery post is the positive electrode, and the thinner end is the negative electrode. At the same time, the color of the battery post can be identified, with the positive electrode post appearing dark brown and the negative electrode appearing dark gray. In addition, some batteries have positive and negative markings represented by English letters, where P represents the positive electrode and N represents the negative electrode. This should not be mistaken during maintenance and charging.
