5號電(dian)(dian)池(chi)(chi)劃(hua)分(fen)為(wei)一次(ci)電(dian)(dian)池(chi)(chi)和(he)二次(ci)電(dian)(dian)池(chi)(chi)，因此，5號電(dian)(dian)池(chi)(chi)容量(liang)可分(fen)為(wei)可充(chong)5號電(dian)(dian)池(chi)(chi)容量(liang)與不可充(chong)5號電(dian)(dian)池(chi)(chi)容量(liang)。

不可(ke)充5號(hao)電(dian)(dian)池又分為碳性和堿性電(dian)(dian)池，通(tong)常，不可(ke)充5號(hao)電(dian)(dian)池容量的計算方法(fa)為：以(yi)3.9Ω恒阻放(fang)電(dian)(dian)由(you)工作電(dian)(dian)壓（1.5V）下降到終(zhong)止電(dian)(dian)壓（0.9V）時(shi)的時(shi)間長度。

5號(hao)(hao)碳(tan)(tan)(tan)性電(dian)(dian)(dian)(dian)池(chi)容量：目(mu)前，市(shi)面上(shang)的(de)(de)(de)5號(hao)(hao)碳(tan)(tan)(tan)性電(dian)(dian)(dian)(dian)池(chi)通常都是高功(gong)率的(de)(de)(de)P型電(dian)(dian)(dian)(dian)池(chi)，5號(hao)(hao)碳(tan)(tan)(tan)性電(dian)(dian)(dian)(dian)池(chi)容量一(yi)般在放(fang)電(dian)(dian)(dian)(dian)55分(fen)鐘以上(shang)，但因(yin)不(bu)同的(de)(de)(de)廠家設計而有所不(bu)同，東莞鉅大一(yi)款開(kai)路電(dian)(dian)(dian)(dian)壓為1.65V的(de)(de)(de)碳(tan)(tan)(tan)性電(dian)(dian)(dian)(dian)池(chi)可(ke)以放(fang)電(dian)(dian)(dian)(dian)90分(fen)鐘，是業內容量比較高容量的(de)(de)(de)5號(hao)(hao)碳(tan)(tan)(tan)性電(dian)(dian)(dian)(dian)池(chi)。

5號(hao)堿性電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)：一般情況下(xia)，3.9Ω放(fang)電(dian)(dian)(dian)(dian)可達6個小時以(yi)上，因(yin)(yin)為堿性電(dian)(dian)(dian)(dian)池(chi)可以(yi)用大電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)，因(yin)(yin)此，也可以(yi)用恒流放(fang)電(dian)(dian)(dian)(dian)測定(ding)其容(rong)量(liang)。通(tong)常(chang)，小電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)下(xia)，5號(hao)堿性電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)大約在1800~2000mAh之間。

可充(chong)電(dian)(dian)5號電(dian)(dian)池有鎳鎘電(dian)(dian)池和(he)鎳氫電(dian)(dian)池，充(chong)電(dian)(dian)電(dian)(dian)池容量單位一般為mAh，偶爾(er)會采用Ah單位，在數值(zhi)上(shang)等于放(fang)(fang)電(dian)(dian)電(dian)(dian)流(liu)與放(fang)(fang)電(dian)(dian)時間的乘積(ji)。

5號鎳(nie)(nie)鎘(ge)電(dian)池(chi)(chi)容(rong)量：因環保(bao)法規的(de)限制(zhi)，鎳(nie)(nie)鎘(ge)電(dian)池(chi)(chi)正(zheng)在逐漸退出市(shi)場(chang)，但在某些要求(qiu)低價的(de)場(chang)合鎳(nie)(nie)鎘(ge)電(dian)池(chi)(chi)還有(you)一定的(de)市(shi)場(chang)，5號鎳(nie)(nie)鎘(ge)電(dian)池(chi)(chi)容(rong)量一般(ban)為500~700mAh，其中GP、日(ri)立、松下的(de)5號鎳(nie)(nie)鎘(ge)電(dian)池(chi)(chi)容(rong)量可以做的(de)高一些。

5號(hao)鎳(nie)(nie)氫電池(chi)(chi)容量：一般都可以(yi)做到1200~1300mAh，是5號(hao)鎳(nie)(nie)鎘(ge)電池(chi)(chi)容量的(de)兩倍，由于鎳(nie)(nie)氫電池(chi)(chi)比鎳(nie)(nie)鎘(ge)電池(chi)(chi)有許多(duo)工作優(you)勢，而(er)且又被(bei)開發出新的(de)用途，因(yin)此(ci)得以(yi)廣泛采用，5號(hao)鎳(nie)(nie)氫電池(chi)(chi)容量做的(de)大(da)而(er)穩的(de)有GP、日系(xi)企業(ye)、國(guo)內有科(ke)力遠、東莞鉅大(da)、深圳倍特(te)力等名企。但名牌鎳(nie)(nie)氫電池(chi)(chi)被(bei)仿冒(mao)的(de)現象(xiang)也很普遍。

鋰離子電池(chi)中有一(yi)款14500鋰電池(chi)，因其(qi)外形尺寸與(yu)其(qi)5號(hao)電池(chi)接近(jin)，故而也被冠以5號(hao)鋰電池(chi)之名(ming)，這種5號(hao)電池(chi)容量可(ke)以設計成500~900mAh，但其(qi)充(chong)放電壽(shou)命卻遠超5號(hao)鎳氫電池(chi)。
