【干(gan)電池容量】5號(hao)干(gan)電池容量 7號(hao)干(gan)電池容量

5號電池劃分為一次電池和二次電池，因此，5號(hao)電池(chi)(chi)容(rong)量可分為可充5號(hao)電池(chi)(chi)容(rong)量與不(bu)可充5號(hao)電池(chi)(chi)容(rong)量。

不可(ke)充5號電(dian)(dian)池(chi)又分(fen)為碳性(xing)和(he)堿性(xing)電(dian)(dian)池(chi)，通常，不可(ke)充5號電(dian)(dian)池(chi)容量的計算方法為：以3.9Ω恒(heng)阻放電(dian)(dian)由工作(zuo)電(dian)(dian)壓(ya)（1.5V）下降到終止電(dian)(dian)壓(ya)（0.9V）時的時間長度(du)。

5號碳性電池容量：目前(qian)，市面(mian)上(shang)的5號(hao)碳(tan)性電池(chi)通常都是高功(gong)率的P型電池(chi)， 5號(hao)碳(tan)性電池(chi)容(rong)量(liang)一(yi)般在放(fang)電55分鐘以(yi)上(shang)，但因(yin)不(bu)同(tong)的廠家(jia)設計(ji)而有所不(bu)同(tong)，東莞鉅大一(yi)款開路電壓為1.65V的碳(tan)性電池(chi)可以(yi)放(fang)電90分鐘，是業內容(rong)量(liang)比較高容(rong)量(liang)的5號(hao)碳(tan)性電池(chi)。

5號堿性電池容量：一般情況下，3.9Ω放(fang)電(dian)(dian)(dian)(dian)(dian)可(ke)達(da)6個小時(shi)以上，因為堿(jian)性電(dian)(dian)(dian)(dian)(dian)池可(ke)以用大(da)(da)電(dian)(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)(dian)，因此，也(ye)可(ke)以用恒流(liu)放(fang)電(dian)(dian)(dian)(dian)(dian)測定其容量(liang)。通常(chang)，小電(dian)(dian)(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)(dian)(dian)下，5號(hao)堿(jian)性電(dian)(dian)(dian)(dian)(dian)池容量(liang)大(da)(da)約在1800~2000mAh之間。

可充電(dian)(dian)(dian)5號電(dian)(dian)(dian)池有鎳鎘電(dian)(dian)(dian)池和鎳氫電(dian)(dian)(dian)池，充電(dian)(dian)(dian)電(dian)(dian)(dian)池容(rong)量單位一(yi)般為(wei)mAh，偶爾會采用Ah單位，在數(shu)值上等(deng)于放電(dian)(dian)(dian)電(dian)(dian)(dian)流與放電(dian)(dian)(dian)時間的乘積(ji)。

5號鎳鎘電池容量：因環保法規的(de)限制，鎳鎘(ge)電(dian)池正在逐(zhu)漸退出(chu)市場(chang)，但在某(mou)些要(yao)求低(di)價的(de)場(chang)合鎳鎘(ge)電(dian)池還(huan)有(you)一定的(de)市場(chang)，5號鎳鎘(ge)電(dian)池容量(liang)一般為500~700mAh，其(qi)中GP、日立、松下的(de)5號鎳鎘(ge)電(dian)池容量(liang)可(ke)以(yi)做的(de)高一些。

5號鎳氫電池容量：一般(ban)都(dou)可以做到(dao)1200~1300mAh，是5號鎳鎘(ge)電(dian)池(chi)(chi)容量(liang)的(de)(de)(de)兩倍，由于鎳氫電(dian)池(chi)(chi)比鎳鎘(ge)電(dian)池(chi)(chi)有許多工作優勢，而且又被開發(fa)出新的(de)(de)(de)用(yong)途，因此(ci)得以廣(guang)泛采用(yong)， 5號鎳氫電(dian)池(chi)(chi)容量(liang)做的(de)(de)(de)大而穩的(de)(de)(de)有GP、日系企業(ye)、國內有科力(li)遠、東莞鉅(ju)大、深圳倍特力(li)等名企。但名牌鎳氫電(dian)池(chi)(chi)被仿冒的(de)(de)(de)現(xian)象也很普(pu)遍。

鋰(li)離(li)子電(dian)池(chi)中有一(yi)款14500鋰(li)電(dian)池(chi)，因其外(wai)形尺寸與其5號(hao)電(dian)池(chi)接近，故而也被(bei)冠以5號(hao)鋰(li)電(dian)池(chi)之名，這種5號(hao)電(dian)池(chi)容量可以設計成500~900mAh，但其充放電(dian)壽命卻遠超5號(hao)鎳氫電(dian)池(chi)。

7號(hao)電池從性質上分(fen)，包括一(yi)次7號(hao)電池和二(er)次7號(hao)電池，7號(hao)電池容(rong)量也因此被分(fen)為一(yi)次7號(hao)電池容(rong)量和二(er)次7號(hao)電池容(rong)量

可做成7號外形的一次電(dian)(dian)(dian)池分為碳(tan)性(xing)電(dian)(dian)(dian)池和(he)堿性(xing)電(dian)(dian)(dian)池，通常，它們的放(fang)電(dian)(dian)(dian)容(rong)量(liang)是指從(cong)標稱電(dian)(dian)(dian)壓(ya)（1.5V）放(fang)電(dian)(dian)(dian)到終止電(dian)(dian)(dian)壓(ya)(0.9V)的時間長度(du)，丈量(liang)方法為恒阻放(fang)電(dian)(dian)(dian)，人們常說的電(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)幾分鐘，指的是在3.9Ω放(fang)電(dian)(dian)(dian)制(zhi)度(du)下(xia)的容(rong)量(liang)。

7號碳性電池容量：按照IEC標準(zhun)，碳(tan)性電池(chi)可以14.8v 2200mah分(fen)為(wei)三種類型(xing)：P型(xing)（高(gao)功(gong)率電池(chi)）、C型(xing)（高(gao)容量電池(chi)）和(he)第一(yi)代(dai)的S型(xing)糊式電池(chi)。

S型電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)曾經被淘汰，在它的(de)基礎上展(zhan)開出(chu)了C型紙板電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，后者(zhe)用(yong)30~70%的(de)高(gao)活性錳替代了自然錳，而且正極填(tian)充量進步了30%，所以(yi)，容量得以(yi)進步，C型電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)多用(yong)于(yu)(yu)(yu)小電(dian)(dian)流放(fang)(fang)電(dian)(dian)場(chang)所，如鐘表、遙控器、收音(yin)機、手電(dian)(dian)筒等(deng)。P型電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)正極全部采(cai)用(yong)高(gao)活性錳，性能(neng)大(da)(da)大(da)(da)提升(sheng)，可用(yong)于(yu)(yu)(yu)大(da)(da)電(dian)(dian)流放(fang)(fang)電(dian)(dian)，如相機、閃光(guang)燈(deng)，不(bu)過，由于(yu)(yu)(yu)堿性電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)市(shi)(shi)場(chang)占有(you)率(lv)起(qi)來越大(da)(da)，所以(yi)，P型電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)往(wang)常也主要是用(yong)于(yu)(yu)(yu)18650 2600mah鋰(li)電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)原C型號電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)市(shi)(shi)場(chang)而C型電(dian)(dian)池(chi)(chi)(chi)(chi)(chi)基本(ben)退出(chu)市(shi)(shi)場(chang)。

7號(hao)碳(tan)性電(dian)(dian)(dian)池容量由于電(dian)(dian)(dian)池消費(fei)廠(chang)家配(pei)方的不同而(er)有(you)差別(bie)，在3.9Ω放電(dian)(dian)(dian)制(zhi)度下，普通在25~35分鐘(zhong)(zhong)之間(jian)，東莞(guan)鉅大有(you)一款(kuan)環保碳(tan)性電(dian)(dian)(dian)池，其標稱放電(dian)(dian)(dian)時(shi)間(jian)35分鐘(zhong)(zhong)，理論(lun)放電(dian)(dian)(dian)接近40分鐘(zhong)(zhong)，這(zhe)是(shi)比(bi)較高容量的7號(hao)碳(tan)性電(dian)(dian)(dian)池。

7號堿性電池容量：在3.9Ω放(fang)電(dian)(dian)(dian)方式下，7號(hao)堿(jian)性電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)(rong)量(liang)(liang)普通可(ke)以抵(di)達7號(hao)碳性電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)(rong)量(liang)(liang)的(de)4~5倍，在數值表(biao)現上，為(wei)放(fang)電(dian)(dian)(dian)時(shi)(shi)間的(de)延長，東(dong)莞鉅大該型(xing)號(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)放(fang)電(dian)(dian)(dian)時(shi)(shi)間為(wei)2.6小時(shi)(shi)。同時(shi)(shi)，堿(jian)性電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)結(jie)構特性更耐受大電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)，因而(er)，該款電(dian)(dian)(dian)池(chi)(chi)(chi)用(yong)500mAh電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)時(shi)(shi)間約為(wei)55分鐘，假定改(gai)用(yong)小電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)，則這款7號(hao)電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)(rong)量(liang)(liang)大約在800~1200mAh之間。

可做成(cheng)7號(hao)外形的二次電池有鎳(nie)鎘電池和(he)鎳(nie)氫電池，二次電池的容量單(dan)位為mAh，或者Ah，表(biao)示在某一個放電電流(liu)下的耐用時間。

7號鎳鎘電池容量：其標稱(cheng)電(dian)壓為了(le)1.2V，終(zhong)止電(dian)壓用8小時率放(fang)電(dian)為1.1V，10ah電(dian)池在這一條件下(xia)，鎳鎘電(dian)池的設(she)計容(rong)量(liang)在500mAh以內，但鎘污染(ran)環(huan)境，而且在充放(fang)電(dian)一定次數后電(dian)量(liang)會降落(luo)到80%，壽命比同類型鎳氫(qing)少，因(yin)此，正(zheng)被鎳氫(qing)電(dian)池全(quan)面取代而退出市場。

7號鎳氫電池容量：鎳(nie)氫電池(chi)的標(biao)稱電壓為(wei)1.2V，終止電壓為(wei)1.0V，主流7號鎳(nie)氫電池(chi)容(rong)量可(ke)以抵達650~800mAh。

由(you)(you)于鎳氫電池(chi)占領了鎳鎘(ge)電池(chi)的(de)原有市(shi)場，而(er)又有自己的(de)新市(shi)場故而(er)成為(wei)市(shi)場新寵，難免(mian)呈(cheng)現一些非理性行(xing)為(wei)，7號(hao)(hao)電池(chi)容(rong)量虛標現象就(jiu)是其(qi)一。目前，國內(nei)做到800mAh曾經相當(dang)不錯(cuo)了，假定(ding)遇到標注1000mAh以上的(de)有可能就(jiu)是虛標了。由(you)(you)于7號(hao)(hao)鎳氫電池(chi)容(rong)量最終是由(you)(you)其(qi)材質所決議的(de)。
