【干電(dian)池(chi)(chi)容量(liang)】5號(hao)干電(dian)池(chi)(chi)容量(liang) 7號(hao)干電(dian)池(chi)(chi)容量(liang)

5號電池劃分為一次電池和二次電池，因此，5號電池容量(liang)可(ke)(ke)分(fen)為可(ke)(ke)充5號電池容量(liang)與不可(ke)(ke)充5號電池容量(liang)。

不可充(chong)5號(hao)(hao)電池又(you)分(fen)為碳性和堿性電池，通常，不可充(chong)5號(hao)(hao)電池容量(liang)的(de)計算方法為：以3.9Ω恒阻放電由(you)工作電壓（1.5V）下降到終(zhong)止(zhi)電壓（0.9V）時的(de)時間長度。

5號碳性電池容量：目(mu)前，市(shi)面上的(de)(de)5號碳性(xing)電池(chi)通常都是高功率的(de)(de)P型電池(chi)， 5號碳性(xing)電池(chi)容(rong)量一般在放電55分鐘(zhong)以上，但因不同(tong)的(de)(de)廠家設計而有所不同(tong)，東莞鉅大一款開路電壓為1.65V的(de)(de)碳性(xing)電池(chi)可以放電90分鐘(zhong)，是業內容(rong)量比較高容(rong)量的(de)(de)5號碳性(xing)電池(chi)。

5號堿性電池容量：一般(ban)情況下，3.9Ω放(fang)電(dian)(dian)可(ke)達6個(ge)小(xiao)(xiao)時以(yi)(yi)上，因為(wei)堿性(xing)電(dian)(dian)池可(ke)以(yi)(yi)用(yong)大(da)電(dian)(dian)流放(fang)電(dian)(dian)，因此，也可(ke)以(yi)(yi)用(yong)恒流放(fang)電(dian)(dian)測定其容(rong)量(liang)。通(tong)常，小(xiao)(xiao)電(dian)(dian)流放(fang)電(dian)(dian)下，5號堿性(xing)電(dian)(dian)池容(rong)量(liang)大(da)約在1800~2000mAh之間。

可充(chong)電(dian)(dian)(dian)5號電(dian)(dian)(dian)池(chi)有鎳(nie)鎘電(dian)(dian)(dian)池(chi)和(he)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(dan)位一般為mAh，偶爾會采用Ah單(dan)位，在數值上等于放電(dian)(dian)(dian)電(dian)(dian)(dian)流與放電(dian)(dian)(dian)時間的乘(cheng)積。

5號鎳鎘電池容量：因環保法規的(de)限制，鎳(nie)鎘(ge)電池(chi)正在逐漸退出市場(chang)，但(dan)在某(mou)些(xie)要求低(di)價(jia)的(de)場(chang)合鎳(nie)鎘(ge)電池(chi)還有一(yi)定的(de)市場(chang)，5號鎳(nie)鎘(ge)電池(chi)容量一(yi)般為500~700mAh，其中GP、日立、松下的(de)5號鎳(nie)鎘(ge)電池(chi)容量可以(yi)做的(de)高一(yi)些(xie)。

5號鎳氫電池容量：一般都(dou)可(ke)以做到1200~1300mAh，是5號鎳鎘電(dian)池容量的(de)(de)兩倍(bei)，由于鎳氫(qing)電(dian)池比鎳鎘電(dian)池有(you)(you)許(xu)多工作優勢，而且又被開發出新的(de)(de)用途，因此得以廣泛采用， 5號鎳氫(qing)電(dian)池容量做的(de)(de)大(da)而穩(wen)的(de)(de)有(you)(you)GP、日系企業、國內有(you)(you)科力遠、東莞(guan)鉅大(da)、深圳倍(bei)特(te)力等名企。但名牌鎳氫(qing)電(dian)池被仿(fang)冒的(de)(de)現象也很普(pu)遍(bian)。

鋰(li)(li)離(li)子電(dian)池(chi)中有一款14500鋰(li)(li)電(dian)池(chi)，因其外形尺寸與其5號(hao)(hao)電(dian)池(chi)接近，故而也被冠以5號(hao)(hao)鋰(li)(li)電(dian)池(chi)之名，這(zhe)種5號(hao)(hao)電(dian)池(chi)容量可(ke)以設計成500~900mAh，但其充放電(dian)壽命卻遠超5號(hao)(hao)鎳氫電(dian)池(chi)。

7號(hao)(hao)(hao)電(dian)(dian)池(chi)從性質上分，包(bao)括一次(ci)(ci)7號(hao)(hao)(hao)電(dian)(dian)池(chi)和二次(ci)(ci)7號(hao)(hao)(hao)電(dian)(dian)池(chi)，7號(hao)(hao)(hao)電(dian)(dian)池(chi)容量(liang)也因(yin)此被分為一次(ci)(ci)7號(hao)(hao)(hao)電(dian)(dian)池(chi)容量(liang)和二次(ci)(ci)7號(hao)(hao)(hao)電(dian)(dian)池(chi)容量(liang)

可做成7號(hao)外形的(de)一次電(dian)(dian)池分為碳(tan)性(xing)電(dian)(dian)池和堿性(xing)電(dian)(dian)池，通常，它(ta)們的(de)放電(dian)(dian)容量是指從標(biao)稱電(dian)(dian)壓（1.5V）放電(dian)(dian)到(dao)終止(zhi)電(dian)(dian)壓(0.9V)的(de)時(shi)間(jian)長度，丈量方法為恒阻放電(dian)(dian)，人們常說的(de)電(dian)(dian)池放電(dian)(dian)幾(ji)分鐘，指的(de)是在3.9Ω放電(dian)(dian)制(zhi)度下(xia)的(de)容量。

7號碳性電池容量：按照IEC標準(zhun)，碳性電(dian)池(chi)可以14.8v 2200mah分為三種類型(xing)：P型(xing)（高(gao)功率(lv)電(dian)池(chi)）、C型(xing)（高(gao)容量電(dian)池(chi)）和第一代的S型(xing)糊式電(dian)池(chi)。

S型電(dian)(dian)池(chi)(chi)(chi)(chi)曾經(jing)被淘汰，在它的基礎(chu)上(shang)展開出(chu)了(le)C型紙板電(dian)(dian)池(chi)(chi)(chi)(chi)，后者用(yong)30~70%的高活性錳替代了(le)自然錳，而(er)且正極填(tian)充量(liang)進步了(le)30%，所以，容量(liang)得以進步，C型電(dian)(dian)池(chi)(chi)(chi)(chi)多用(yong)于(yu)小電(dian)(dian)流放電(dian)(dian)場(chang)所，如鐘表(biao)、遙控器(qi)、收(shou)音(yin)機(ji)、手電(dian)(dian)筒等(deng)。P型電(dian)(dian)池(chi)(chi)(chi)(chi)正極全(quan)部(bu)采(cai)用(yong)高活性錳，性能大(da)(da)大(da)(da)提升，可用(yong)于(yu)大(da)(da)電(dian)(dian)流放電(dian)(dian)，如相機(ji)、閃光燈，不過，由于(yu)堿(jian)性電(dian)(dian)池(chi)(chi)(chi)(chi)的市場(chang)占(zhan)有率起來(lai)越大(da)(da)，所以，P型電(dian)(dian)池(chi)(chi)(chi)(chi)往常也主要是用(yong)于(yu)18650 2600mah鋰電(dian)(dian)池(chi)(chi)(chi)(chi)原C型號電(dian)(dian)池(chi)(chi)(chi)(chi)的市場(chang)而(er)C型電(dian)(dian)池(chi)(chi)(chi)(chi)基本(ben)退出(chu)市場(chang)。

7號(hao)碳(tan)性電(dian)池(chi)容(rong)量由于電(dian)池(chi)消費廠家配方的不同而有差別，在3.9Ω放(fang)電(dian)制度下，普通在25~35分(fen)(fen)鐘(zhong)之間(jian)(jian)，東莞鉅大有一(yi)款環保碳(tan)性電(dian)池(chi)，其(qi)標稱放(fang)電(dian)時間(jian)(jian)35分(fen)(fen)鐘(zhong)，理論放(fang)電(dian)接近40分(fen)(fen)鐘(zhong)，這是比(bi)較高(gao)容(rong)量的7號(hao)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)方式下，7號(hao)堿(jian)性(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)普通(tong)可(ke)以抵達7號(hao)碳性(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)的(de)(de)4~5倍，在數值表現(xian)上，為放(fang)電(dian)(dian)(dian)(dian)時(shi)(shi)間的(de)(de)延長(chang)，東莞鉅大(da)該型號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)放(fang)電(dian)(dian)(dian)(dian)時(shi)(shi)間為2.6小(xiao)時(shi)(shi)。同時(shi)(shi)，堿(jian)性(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)結構特性(xing)(xing)更耐受大(da)電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)，因而，該款電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)用(yong)500mAh電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)時(shi)(shi)間約為55分鐘，假定改用(yong)小(xiao)電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)，則這款7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)大(da)約在800~1200mAh之間。

可做(zuo)成7號外形的(de)二次電(dian)(dian)池有鎳鎘電(dian)(dian)池和鎳氫電(dian)(dian)池，二次電(dian)(dian)池的(de)容(rong)量單(dan)位為(wei)mAh，或者Ah，表示在某一(yi)個放電(dian)(dian)電(dian)(dian)流(liu)下的(de)耐用時間。

7號鎳鎘電池容量：其標稱(cheng)電(dian)(dian)壓為了(le)1.2V，終止(zhi)電(dian)(dian)壓用8小時率放電(dian)(dian)為1.1V，10ah電(dian)(dian)池(chi)在(zai)這一條件下，鎳鎘(ge)電(dian)(dian)池(chi)的設計容(rong)量(liang)在(zai)500mAh以(yi)內(nei)，但鎘(ge)污染(ran)環境(jing)，而且在(zai)充放電(dian)(dian)一定(ding)次(ci)數后(hou)電(dian)(dian)量(liang)會(hui)降落到80%，壽命比(bi)同類型鎳氫(qing)少，因此，正被(bei)鎳氫(qing)電(dian)(dian)池(chi)全面取代(dai)而退(tui)出市場。

7號鎳氫電池容量：鎳氫電(dian)池(chi)的標稱(cheng)電(dian)壓為1.2V，終止電(dian)壓為1.0V，主(zhu)流7號鎳氫電(dian)池(chi)容量可以抵達650~800mAh。

由于(yu)鎳氫電池(chi)占領了(le)(le)鎳鎘電池(chi)的(de)原有(you)市場(chang)，而又有(you)自己的(de)新市場(chang)故(gu)而成為(wei)市場(chang)新寵，難免呈現(xian)一些(xie)非理性行為(wei)，7號電池(chi)容量(liang)虛標(biao)現(xian)象就是其一。目(mu)前，國內做到800mAh曾經相當(dang)不(bu)錯了(le)(le)，假定(ding)遇到標(biao)注1000mAh以上的(de)有(you)可能(neng)就是虛標(biao)了(le)(le)。由于(yu)7號鎳氫電池(chi)容量(liang)最(zui)終是由其材質所決議的(de)。
