aaa電池是什么

aaa電(dian)(dian)(dian)(dian)池(chi)(chi)，是一(yi)種美國的(de)干電(dian)(dian)(dian)(dian)池(chi)(chi)標(biao)準，中國大(da)陸的(de)7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)或(huo)臺灣的(de)4號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)標(biao)準與其兼容。電(dian)(dian)(dian)(dian)池(chi)(chi)呈圓(yuan)柱形，高43.6毫米，直徑(jing)10.1毫米。是一(yi)種常(chang)見的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，比aa電(dian)(dian)(dian)(dian)池(chi)(chi)小。常(chang)用(yong)于體(ti)積較小，耗電(dian)(dian)(dian)(dian)量不太高的(de)電(dian)(dian)(dian)(dian)子產品如(ru)MP3播放(fang)器(qi)、小型(xing)遙控器(qi)等。既有一(yi)次(ci)性(xing)的(de)堿(jian)性(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)，也有可充(chong)電(dian)(dian)(dian)(dian)的(de)鎳氫、鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)。

aaa電池是幾號

aaa就是我們通常所說的7號電池。一般尺寸為：直徑11mm，高度44mm。

aa電池是幾號

aa就(jiu)是通常所(suo)說的5號電池。一般尺寸為：直徑14mm，高度49mm。

aa和aaa電池區別

1、大小不同

aa號電(dian)池(chi)的一(yi)般尺寸(cun)就是直(zhi)徑14毫米(mi)、高度(du)在49毫米(mi)。而(er)aaa號電(dian)池(chi)要(yao)比aa號電(dian)池(chi)小一(yi)點，尺寸(cun)是直(zhi)徑11毫米(mi)、高度(du)在44毫米(mi)。我(wo)們從電(dian)池(chi)的外觀來看就可(ke)以發現(xian)兩者有(you)很大的區別。

2、蓄電量不同

同種類(lei)型(xing)的電(dian)(dian)池，由于aa號電(dian)(dian)池要(yao)比(bi)aaa號電(dian)(dian)池大，所以aa號電(dian)(dian)池的電(dian)(dian)量要(yao)比(bi)aaa號電(dian)(dian)池多出一部分。

3、用途上不同

aa電池和(he)aaa電(dian)池(chi)(chi)的(de)用途都(dou)比較廣(guang)泛，比如(ru)遙控(kong)器，電(dian)子(zi)玩具(ju)等其他產品(pin)上(shang)面(mian)。因為(wei)體積(ji)上(shang)的(de)差異，aa電(dian)池(chi)(chi)的(de)容量要(yao)比aaa電(dian)池(chi)(chi)的(de)大。所(suo)以不(bu)難發現大一(yi)些的(de)電(dian)子(zi)產品(pin)通常會(hui)用到aa號電(dian)池(chi)(chi)，因為(wei)它所(suo)需(xu)要(yao)的(de)電(dian)量更多，這樣使(shi)用更持久(jiu)。
