5號(hao)電(dian)池劃分為(wei)(wei)一次(ci)電(dian)池和二次(ci)電(dian)池，因此，5號(hao)電(dian)池容(rong)量可(ke)分為(wei)(wei)可(ke)充5號(hao)電(dian)池容(rong)量與不可(ke)充5號(hao)電(dian)池容(rong)量。

不可充(chong)5號(hao)電(dian)池(chi)又分為碳性和(he)堿性電(dian)池(chi)，通常，不可充(chong)5號(hao)電(dian)池(chi)容量的計算方法為：以3.9Ω恒阻放電(dian)由工作(zuo)電(dian)壓(ya)（1.5V）下降到終止電(dian)壓(ya)（0.9V）時的時間長度(du)。

5號碳(tan)性電(dian)(dian)(dian)(dian)(dian)池容量(liang)：目前(qian)，市面(mian)上的(de)5號碳(tan)性電(dian)(dian)(dian)(dian)(dian)池通常都是(shi)高功率(lv)的(de)P型(xing)電(dian)(dian)(dian)(dian)(dian)池，5號碳(tan)性電(dian)(dian)(dian)(dian)(dian)池容量(liang)一(yi)般(ban)在放(fang)電(dian)(dian)(dian)(dian)(dian)55分鐘(zhong)以上，但因(yin)不同(tong)的(de)廠家設(she)計而(er)有所不同(tong)，東(dong)莞(guan)鉅大(da)一(yi)款(kuan)開路電(dian)(dian)(dian)(dian)(dian)壓為1.65V的(de)碳(tan)性電(dian)(dian)(dian)(dian)(dian)池可以放(fang)電(dian)(dian)(dian)(dian)(dian)90分鐘(zhong)，是(shi)業內容量(liang)比較高容量(liang)的(de)5號碳(tan)性電(dian)(dian)(dian)(dian)(dian)池。

5號堿性電池容量(liang)：一(yi)般(ban)情(qing)況下，3.9Ω放(fang)電可(ke)達6個小(xiao)(xiao)時以上(shang)，因(yin)為堿性電池可(ke)以用(yong)(yong)大電流放(fang)電，因(yin)此(ci)，也可(ke)以用(yong)(yong)恒流放(fang)電測定(ding)其(qi)容量(liang)。通常，小(xiao)(xiao)電流放(fang)電下，5號堿性電池容量(liang)大約在1800~2000mAh之間(jian)。

可充電(dian)5號電(dian)池有鎳鎘電(dian)池和鎳氫電(dian)池，充電(dian)電(dian)池容(rong)量單位(wei)一(yi)般為mAh，偶爾會采用Ah單位(wei)，在數值上(shang)等于放電(dian)電(dian)流與放電(dian)時間的乘積。

5號鎳(nie)鎘(ge)(ge)電(dian)池(chi)(chi)容(rong)量：因環(huan)保法(fa)規(gui)的限制，鎳(nie)鎘(ge)(ge)電(dian)池(chi)(chi)正(zheng)在(zai)逐漸退出(chu)市(shi)場(chang)，但在(zai)某些要求低價的場(chang)合鎳(nie)鎘(ge)(ge)電(dian)池(chi)(chi)還有(you)一(yi)定的市(shi)場(chang)，5號鎳(nie)鎘(ge)(ge)電(dian)池(chi)(chi)容(rong)量一(yi)般為500~700mAh，其(qi)中GP、日立、松下的5號鎳(nie)鎘(ge)(ge)電(dian)池(chi)(chi)容(rong)量可以做的高一(yi)些。

5號鎳(nie)(nie)氫(qing)電(dian)(dian)池(chi)(chi)容(rong)量：一般都可以做(zuo)到1200~1300mAh，是5號鎳(nie)(nie)鎘電(dian)(dian)池(chi)(chi)容(rong)量的(de)兩倍，由于鎳(nie)(nie)氫(qing)電(dian)(dian)池(chi)(chi)比鎳(nie)(nie)鎘電(dian)(dian)池(chi)(chi)有許多工作優勢，而(er)且又被開發(fa)出新的(de)用途，因此得以廣泛(fan)采用，5號鎳(nie)(nie)氫(qing)電(dian)(dian)池(chi)(chi)容(rong)量做(zuo)的(de)大(da)而(er)穩的(de)有GP、日系企(qi)業、國(guo)內有科(ke)力(li)遠(yuan)、東莞鉅(ju)大(da)、深圳倍特(te)力(li)等名企(qi)。但名牌鎳(nie)(nie)氫(qing)電(dian)(dian)池(chi)(chi)被仿(fang)冒的(de)現(xian)象(xiang)也很普遍。

鋰(li)(li)離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)中(zhong)有(you)一(yi)款(kuan)14500鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)，因其(qi)外形尺寸(cun)與其(qi)5號電(dian)(dian)(dian)(dian)池(chi)(chi)接(jie)近，故(gu)而(er)也被冠以(yi)5號鋰(li)(li)電(dian)(dian)(dian)(dian)池(chi)(chi)之(zhi)名，這(zhe)種5號電(dian)(dian)(dian)(dian)池(chi)(chi)容量(liang)可以(yi)設(she)計成500~900mAh，但其(qi)充放電(dian)(dian)(dian)(dian)壽命卻遠(yuan)超5號鎳(nie)氫電(dian)(dian)(dian)(dian)池(chi)(chi)。
