5號電池和7號電池說日常生活中常見的兩款型號的電池，但還是有很多人分不清楚，還經常買錯，今天格瑞普電池就跟大家介紹一下5號和7號電池哪個大?

　　5號和7號電池哪個大?

　　在常見(jian)的(de)(de)電(dian)池(chi)規(gui)格中，5號電(dian)池(chi)一(yi)般比7號電(dian)池(chi)更(geng)大。這里的(de)(de)“大小”指的(de)(de)是電(dian)池(chi)的(de)(de)物理尺寸和容量(liang)。

　　電(dian)池(chi)(chi)的(de)尺(chi)寸命名(ming)通常是根據國際標準(zhun)規定的(de)代號(hao)(hao)，例如5號(hao)(hao)電(dian)池(chi)(chi)和7號(hao)(hao)電(dian)池(chi)(chi)。這些(xie)號(hao)(hao)碼代表了不(bu)同類型和尺(chi)寸的(de)電(dian)池(chi)(chi)。一般(ban)情況下，5號(hao)(hao)電(dian)池(chi)(chi)比7號(hao)(hao)電(dian)池(chi)(chi)更(geng)(geng)長(chang)、更(geng)(geng)大，因(yin)此能夠容納更(geng)(geng)多(duo)的(de)電(dian)荷并提供更(geng)(geng)長(chang)時(shi)間的(de)使(shi)用。

　　5號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)直徑(jing)是(shi)14mm，7號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)直徑(jing)是(shi)10.5mm，5號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)比(bi)(bi)7號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)大;5號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)高度是(shi)50mm，7號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)高度是(shi)44.5mm，5號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)比(bi)(bi)7號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)要高。也就是(shi)說5號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)體(ti)積比(bi)(bi)7號(hao)(hao)(hao)(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)體(ti)積要大些。

　　5號(hao)電(dian)(dian)池(chi)(chi)(chi)(chi)型號(hao)為(wei)AA或R6，尺(chi)(chi)寸規格尺(chi)(chi)直徑14mm，高度50mm;與1號(hao)電(dian)(dian)池(chi)(chi)(chi)(chi)、2號(hao)電(dian)(dian)池(chi)(chi)(chi)(chi)、3號(hao)電(dian)(dian)池(chi)(chi)(chi)(chi)、7號(hao)電(dian)(dian)池(chi)(chi)(chi)(chi)等區(qu)別是(shi)外(wai)形尺(chi)(chi)寸大小(xiao)不一(yi)樣，共(gong)同點是(shi)都是(shi)屬于鋼殼(ke)圓柱電(dian)(dian)池(chi)(chi)(chi)(chi)。

　　7號(hao)電(dian)(dian)池/LR03/AM4型號(hao)為AAA型電(dian)(dian)池;尺寸：直徑10.5mm;高度44.5mm;5號(hao)電(dian)(dian)池和7號(hao)電(dian)(dian)池的額定電(dian)(dian)壓都(dou)是(shi)1.5V，在外形尺寸和容量上，5號(hao)電(dian)(dian)池都(dou)要大一(yi)點。

　　其他型號如下：

　　1、D型電池(chi)(chi)(大號電池(chi)(chi)/LR20/AM1) 直(zhi)徑ф34.2; 高(gao)度61.5mm。

　　2、C型電池(chi)(2號(hao)電池(chi)/LR14/AM2) 直徑ф26.2; 高度50.0mm。

　　3、AA型電(dian)池(chi)(5號電(dian)池(chi)/LR6/AM3) 直徑ф14.5; 高度50.5mm。

　　4、AAA型電(dian)池(7號電(dian)池/LR03/AM4) 直徑ф10.5; 高度44.5mm。

　　5、AA/2型電池(8號(hao)電池LR1/AM5) 直徑ф11.0; 高度(du)30.0mm。

　　6、AAAA型電(dian)池(9號電(dian)池/LR61/AM6) 直徑ф8.0; 高度39.5mm。

　　7、AAAA/2型電池(chi)(小9號電池(chi)/LR61/AM6) 直徑ф8.0; 高度28.0mm。

　　以上就(jiu)是5號(hao)(hao)和7號(hao)(hao)電(dian)池(chi)(chi)哪(na)個大(da)的介紹,不(bu)同(tong)的地區或(huo)不(bu)同(tong)的國(guo)家可能(neng)會(hui)有不(bu)同(tong)的編號(hao)(hao)系(xi)統，因(yin)(yin)此如果需(xu)要確(que)定(ding)特定(ding)電(dian)池(chi)(chi)規(gui)(gui)格(ge)(ge)的尺(chi)寸和容量，最(zui)好(hao)查(cha)看電(dian)池(chi)(chi)包裝或(huo)相關規(gui)(gui)格(ge)(ge)表以獲得(de)確(que)切的信息(xi)，在實際使(shi)用(yong)中，我們還需(xu)要考慮到(dao)電(dian)池(chi)(chi)的電(dian)壓(ya)和使(shi)用(yong)環境等因(yin)(yin)素(su)。因(yin)(yin)此，在選(xuan)擇電(dian)池(chi)(chi)時，我們需(xu)要根(gen)據實際需(xu)求來確(que)定(ding)使(shi)用(yong)哪(na)個型號(hao)(hao)規(gui)(gui)格(ge)(ge)的電(dian)池(chi)(chi)。
