一、電池幾號是怎么規定的

1、我國是以國際慣(guan)例命名的(de)，圓柱形電池型號分類為：AAA、AA、A、SC、C、D、F型，共七種。

2、AA就是(shi)(shi)(shi)我(wo)們(men)通常所說的5號電(dian)池，日本(ben)是(shi)(shi)(shi)稱為(wei)“単(dan)(dan)3形"，一般尺寸為(wei)：高(gao)度48.0±0.5mm，直(zhi)徑14.1mm±0.2mm；而AAA就是(shi)(shi)(shi)我(wo)們(men)通常所說的7號電(dian)池，日本(ben)是(shi)(shi)(shi)稱為(wei)”単(dan)(dan)4形“，一般尺寸為(wei)：高(gao)度43.6mm±0.5mm，直(zhi)徑10.1mm±0.2mm。

3、只用一(yi)個A表(biao)示型(xing)號(hao)的電(dian)池(chi)(chi)不常見(jian)，這一(yi)系列通(tong)常作(zuo)電(dian)池(chi)(chi)組(zu)里面(mian)的電(dian)池(chi)(chi)芯，老攝像(xiang)機的鎳鎘，鎳氫(qing)電(dian)池(chi)(chi)，幾(ji)乎都是4/5A，或(huo)者4/5SC的電(dian)池(chi)(chi)芯。標準的A(平頭)電(dian)池(chi)(chi)一(yi)般(ban)尺(chi)寸：高度49.0±0.5mm，直(zhi)徑16.8±0.2mm。

4、SC型號也不常見，一(yi)般是電(dian)(dian)池(chi)組(zu)里面(mian)的(de)電(dian)(dian)池(chi)芯，多在電(dian)(dian)動工具和(he)攝像機(ji)以及進口設備上能見到，標(biao)準的(de)SC(平(ping)頭)電(dian)(dian)池(chi)高度42.0±0.5mm，直(zhi)徑(jing)22.1±0.2mm。

5、C型號(hao)也就(jiu)是(shi)二號(hao)電池，標準(zhun)的C(平(ping)頭(tou))電池高度49.5±0.5mm，直徑25.3±0.2mm。

6、D型號(hao)就是(shi)一號(hao)電(dian)(dian)池，用(yong)途廣泛(fan)，民用(yong)，軍工，特異型直流電(dian)(dian)源都能(neng)找到D型電(dian)(dian)池，標準的D(平頭)電(dian)(dian)池高度59.0±0.5mm，直徑(jing)32.3±0.2mm。

7、F型號電池(chi)是動(dong)力(li)電池(chi)的新一代產品，大有取代鉛酸免維護蓄電池(chi)的趨勢，一般都是作電池(chi)芯(xin)。標(biao)準的F(平頭)電池(chi)高度89.0±0.5mm，直徑32.3±0.2mm。

二、電池幾號要怎么區分

可以(yi)從以(yi)下幾個方面區分(fen)：

1、電池的大小

電(dian)(dian)池(chi)(chi)外(wai)形(xing)尺寸上，1號(hao)(hao)電(dian)(dian)池(chi)(chi)直(zhi)徑(jing)為(wei)(wei)34.2mm，高(gao)度為(wei)(wei)61.5mm，2號(hao)(hao)電(dian)(dian)池(chi)(chi)直(zhi)徑(jing)為(wei)(wei)26.2mm，高(gao)度50.0mm，5號(hao)(hao)電(dian)(dian)池(chi)(chi)直(zhi)徑(jing)為(wei)(wei)14.5mm，高(gao)度50.5mm，7號(hao)(hao)電(dian)(dian)池(chi)(chi)直(zhi)徑(jing)為(wei)(wei)10.5mm，高(gao)度44.5mm。1號(hao)(hao)電(dian)(dian)池(chi)(chi)的尺寸最大(da)，2號(hao)(hao)電(dian)(dian)池(chi)(chi)次之，5號(hao)(hao)和7號(hao)(hao)依(yi)次排在2號(hao)(hao)電(dian)(dian)池(chi)(chi)之后。

2、電池的標識

1號電池英文代號為D，2號電池英文代號為C，5號電池英文代號為AA，7號電池英文代號為AAA，這幾個型號的電池標識(shi)可以在(zai)電(dian)池的包裝上(shang)看(kan)到。

3、電池的容量

電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)(rong)量(liang)上區分，也是一號電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)(rong)量(liang)，二號電(dian)(dian)(dian)池(chi)(chi)(chi)次之，五號電(dian)(dian)(dian)池(chi)(chi)(chi)的容(rong)(rong)量(liang)比七號電(dian)(dian)(dian)池(chi)(chi)(chi)的容(rong)(rong)量(liang)大比二號電(dian)(dian)(dian)池(chi)(chi)(chi)的容(rong)(rong)量(liang)小。
