【干(gan)電(dian)池容(rong)量】5號(hao)干(gan)電(dian)池容(rong)量 7號(hao)干(gan)電(dian)池容(rong)量

5號電池劃分為一次電池和二次電池，因此，5號(hao)電(dian)池容量(liang)(liang)可分為可充5號(hao)電(dian)池容量(liang)(liang)與不可充5號(hao)電(dian)池容量(liang)(liang)。

不(bu)可(ke)充5號電(dian)(dian)池又分(fen)為碳性和堿性電(dian)(dian)池，通常，不(bu)可(ke)充5號電(dian)(dian)池容量的(de)計(ji)算方法為：以3.9Ω恒阻(zu)放電(dian)(dian)由工作電(dian)(dian)壓(ya)（1.5V）下降(jiang)到終止電(dian)(dian)壓(ya)（0.9V）時(shi)的(de)時(shi)間長度。

5號碳性電池容量：目(mu)前，市面上的5號碳性(xing)電(dian)(dian)池(chi)(chi)通常(chang)都是高功率的P型電(dian)(dian)池(chi)(chi)， 5號碳性(xing)電(dian)(dian)池(chi)(chi)容(rong)量一(yi)(yi)般在放(fang)電(dian)(dian)55分(fen)鐘以上，但因(yin)不(bu)同的廠(chang)家設計而有所不(bu)同，東莞鉅大一(yi)(yi)款(kuan)開路(lu)電(dian)(dian)壓為1.65V的碳性(xing)電(dian)(dian)池(chi)(chi)可以放(fang)電(dian)(dian)90分(fen)鐘，是業內容(rong)量比較高容(rong)量的5號碳性(xing)電(dian)(dian)池(chi)(chi)。

5號堿性電池容量：一(yi)般情況下(xia)，3.9Ω放(fang)(fang)電(dian)可達(da)6個小(xiao)時以上(shang)，因為堿(jian)性電(dian)池可以用大電(dian)流(liu)放(fang)(fang)電(dian)，因此，也可以用恒(heng)流(liu)放(fang)(fang)電(dian)測定其容(rong)量。通常，小(xiao)電(dian)流(liu)放(fang)(fang)電(dian)下(xia)，5號堿(jian)性電(dian)池容(rong)量大約在1800~2000mAh之(zhi)間。

可充(chong)電(dian)(dian)(dian)5號(hao)電(dian)(dian)(dian)池(chi)有鎳(nie)鎘電(dian)(dian)(dian)池(chi)和鎳(nie)氫電(dian)(dian)(dian)池(chi)，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)容量(liang)單位一般為(wei)mAh，偶(ou)爾(er)會采(cai)用Ah單位，在數值上(shang)等于(yu)放電(dian)(dian)(dian)電(dian)(dian)(dian)流與放電(dian)(dian)(dian)時間的(de)乘積。

5號鎳鎘電池容量：因環保法規(gui)的(de)限制，鎳鎘電(dian)池(chi)(chi)正在(zai)逐(zhu)漸退出市場，但在(zai)某些要求低價的(de)場合鎳鎘電(dian)池(chi)(chi)還有(you)一(yi)定的(de)市場，5號鎳鎘電(dian)池(chi)(chi)容量一(yi)般為500~700mAh，其中GP、日立、松(song)下的(de)5號鎳鎘電(dian)池(chi)(chi)容量可(ke)以做的(de)高一(yi)些。

5號鎳氫電池容量：一般都(dou)可以(yi)做到1200~1300mAh，是(shi)5號(hao)鎳(nie)(nie)鎘電(dian)池(chi)容(rong)(rong)量的(de)(de)兩倍，由于(yu)鎳(nie)(nie)氫(qing)(qing)電(dian)池(chi)比鎳(nie)(nie)鎘電(dian)池(chi)有許多(duo)工作(zuo)優勢，而且又被(bei)開發出新的(de)(de)用途，因(yin)此得以(yi)廣(guang)泛采用， 5號(hao)鎳(nie)(nie)氫(qing)(qing)電(dian)池(chi)容(rong)(rong)量做的(de)(de)大而穩的(de)(de)有GP、日系企業、國內有科力(li)遠、東(dong)莞(guan)鉅大、深圳倍特力(li)等名(ming)企。但名(ming)牌鎳(nie)(nie)氫(qing)(qing)電(dian)池(chi)被(bei)仿冒的(de)(de)現象(xiang)也很普(pu)遍(bian)。

鋰(li)離(li)子電(dian)池(chi)中(zhong)有一款14500鋰(li)電(dian)池(chi)，因其外(wai)形尺(chi)寸與其5號電(dian)池(chi)接近，故而(er)也被冠以(yi)5號鋰(li)電(dian)池(chi)之(zhi)名，這種(zhong)5號電(dian)池(chi)容量可(ke)以(yi)設計成(cheng)500~900mAh，但其充(chong)放(fang)電(dian)壽命卻遠超5號鎳氫電(dian)池(chi)。

7號(hao)電(dian)(dian)池從(cong)性質(zhi)上分，包括一次7號(hao)電(dian)(dian)池和(he)二(er)(er)次7號(hao)電(dian)(dian)池，7號(hao)電(dian)(dian)池容(rong)量也因此(ci)被(bei)分為(wei)一次7號(hao)電(dian)(dian)池容(rong)量和(he)二(er)(er)次7號(hao)電(dian)(dian)池容(rong)量

可做(zuo)成7號外形的一次電(dian)(dian)池(chi)分(fen)(fen)為碳性電(dian)(dian)池(chi)和(he)堿性電(dian)(dian)池(chi)，通(tong)常(chang)，它們的放電(dian)(dian)容量(liang)是指(zhi)(zhi)從標稱(cheng)電(dian)(dian)壓（1.5V）放電(dian)(dian)到終(zhong)止電(dian)(dian)壓(0.9V)的時間長度(du)，丈量(liang)方法為恒阻(zu)放電(dian)(dian)，人們常(chang)說的電(dian)(dian)池(chi)放電(dian)(dian)幾分(fen)(fen)鐘，指(zhi)(zhi)的是在(zai)3.9Ω放電(dian)(dian)制度(du)下的容量(liang)。

7號碳性電池容量：按照IEC標準，碳性(xing)電池(chi)(chi)可(ke)以14.8v 2200mah分為三種(zhong)類型(xing)：P型(xing)（高功率電池(chi)(chi)）、C型(xing)（高容(rong)量電池(chi)(chi)）和第一代的S型(xing)糊式電池(chi)(chi)。

S型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)曾(ceng)經被(bei)淘汰，在它(ta)的(de)基礎上展開出(chu)了(le)C型(xing)(xing)紙板(ban)電(dian)(dian)(dian)(dian)池(chi)，后(hou)者用30~70%的(de)高活(huo)性(xing)錳替(ti)代了(le)自然(ran)錳，而且(qie)正極(ji)(ji)填(tian)充量進(jin)步(bu)了(le)30%，所(suo)以(yi)，容量得(de)以(yi)進(jin)步(bu)，C型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)多用于(yu)(yu)(yu)小(xiao)電(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)場(chang)所(suo)，如(ru)鐘表、遙控器、收(shou)音機(ji)(ji)、手(shou)電(dian)(dian)(dian)(dian)筒(tong)等(deng)。P型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)正極(ji)(ji)全部采用高活(huo)性(xing)錳，性(xing)能大(da)大(da)提(ti)升，可用于(yu)(yu)(yu)大(da)電(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)，如(ru)相機(ji)(ji)、閃(shan)光(guang)燈，不過，由于(yu)(yu)(yu)堿性(xing)電(dian)(dian)(dian)(dian)池(chi)的(de)市(shi)(shi)場(chang)占有率起來越大(da)，所(suo)以(yi)，P型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)往常也主(zhu)要是用于(yu)(yu)(yu)18650 2600mah鋰電(dian)(dian)(dian)(dian)池(chi)原C型(xing)(xing)號(hao)電(dian)(dian)(dian)(dian)池(chi)的(de)市(shi)(shi)場(chang)而C型(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)基本退出(chu)市(shi)(shi)場(chang)。

7號碳(tan)性電(dian)池(chi)容量由于電(dian)池(chi)消費廠家配(pei)方的不同而(er)有(you)差別，在3.9Ω放電(dian)制度(du)下，普通在25~35分鐘(zhong)之(zhi)間，東莞鉅大有(you)一(yi)款(kuan)環保碳(tan)性電(dian)池(chi)，其標稱放電(dian)時間35分鐘(zhong)，理論放電(dian)接(jie)近40分鐘(zhong)，這是比較(jiao)高容量的7號碳(tan)性電(dian)池(chi)。

7號堿性電池容量：在3.9Ω放(fang)電(dian)(dian)(dian)(dian)方式(shi)下(xia)，7號(hao)(hao)堿性電(dian)(dian)(dian)(dian)池(chi)容量普通(tong)可(ke)以(yi)抵達7號(hao)(hao)碳性電(dian)(dian)(dian)(dian)池(chi)容量的4~5倍，在數值表現上(shang)，為放(fang)電(dian)(dian)(dian)(dian)時(shi)間(jian)(jian)的延長(chang)，東莞鉅大(da)該(gai)型號(hao)(hao)電(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)時(shi)間(jian)(jian)為2.6小時(shi)。同時(shi)，堿性電(dian)(dian)(dian)(dian)池(chi)的結構特性更耐(nai)受大(da)電(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)，因而，該(gai)款電(dian)(dian)(dian)(dian)池(chi)用500mAh電(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)時(shi)間(jian)(jian)約為55分(fen)鐘，假定改用小電(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)，則這款7號(hao)(hao)電(dian)(dian)(dian)(dian)池(chi)容量大(da)約在800~1200mAh之間(jian)(jian)。

可做成7號外形的二次(ci)電(dian)池(chi)有鎳(nie)鎘電(dian)池(chi)和鎳(nie)氫電(dian)池(chi)，二次(ci)電(dian)池(chi)的容(rong)量(liang)單位為mAh，或(huo)者Ah，表示在某一個放電(dian)電(dian)流下的耐用時間(jian)。

7號鎳鎘電池容量：其標稱(cheng)電壓為(wei)了(le)1.2V，終止電壓用8小時率放(fang)電為(wei)1.1V，10ah電池在(zai)這(zhe)一條(tiao)件下(xia)，鎳鎘電池的設計容(rong)量(liang)在(zai)500mAh以內，但鎘污(wu)染(ran)環境，而且在(zai)充放(fang)電一定次數(shu)后電量(liang)會(hui)降(jiang)落到80%，壽命比同(tong)類(lei)型鎳氫少，因此，正被鎳氫電池全面(mian)取代而退出市場。

7號鎳氫電池容量：鎳氫(qing)(qing)電(dian)(dian)(dian)池(chi)的標稱電(dian)(dian)(dian)壓為(wei)(wei)1.2V，終止電(dian)(dian)(dian)壓為(wei)(wei)1.0V，主流7號鎳氫(qing)(qing)電(dian)(dian)(dian)池(chi)容量(liang)可以抵達650~800mAh。

由(you)于鎳(nie)氫電(dian)(dian)池占領了鎳(nie)鎘電(dian)(dian)池的(de)原有(you)市場(chang)，而(er)又有(you)自己(ji)的(de)新市場(chang)故而(er)成為市場(chang)新寵(chong)，難免呈現一些(xie)非理性行為，7號電(dian)(dian)池容(rong)(rong)量虛標(biao)現象(xiang)就(jiu)是(shi)其(qi)一。目前(qian)，國內做(zuo)到(dao)800mAh曾(ceng)經相(xiang)當不錯了，假定遇到(dao)標(biao)注(zhu)1000mAh以上的(de)有(you)可能就(jiu)是(shi)虛標(biao)了。由(you)于7號鎳(nie)氫電(dian)(dian)池容(rong)(rong)量最終是(shi)由(you)其(qi)材質所決議的(de)。
