【干(gan)電池(chi)容(rong)量(liang)】5號(hao)干(gan)電池(chi)容(rong)量(liang) 7號(hao)干(gan)電池(chi)容(rong)量(liang)

5號電池劃分為一次電池和二次電池，因此(ci)，5號電池容(rong)量可(ke)分為可(ke)充(chong)5號電池容(rong)量與不可(ke)充(chong)5號電池容(rong)量。

不(bu)可充5號電(dian)池(chi)又分為(wei)碳性和堿性電(dian)池(chi)，通常，不(bu)可充5號電(dian)池(chi)容量的計算方(fang)法為(wei)：以3.9Ω恒阻放(fang)電(dian)由工作(zuo)電(dian)壓(ya)（1.5V）下降到終止(zhi)電(dian)壓(ya)（0.9V）時(shi)的時(shi)間長度。

5號碳性電池容量：目前，市面上(shang)的(de)5號(hao)碳性(xing)電(dian)池(chi)通常(chang)都(dou)是高(gao)功率的(de)P型電(dian)池(chi)， 5號(hao)碳性(xing)電(dian)池(chi)容(rong)量一(yi)般在放(fang)電(dian)55分(fen)鐘以(yi)上(shang)，但因不同的(de)廠家(jia)設計(ji)而有所不同，東莞鉅大一(yi)款(kuan)開(kai)路(lu)電(dian)壓為(wei)1.65V的(de)碳性(xing)電(dian)池(chi)可以(yi)放(fang)電(dian)90分(fen)鐘，是業內容(rong)量比較高(gao)容(rong)量的(de)5號(hao)碳性(xing)電(dian)池(chi)。

5號堿性電池容量：一般情況下，3.9Ω放電(dian)可達6個小時以上，因為堿(jian)性電(dian)池可以用大電(dian)流(liu)(liu)放電(dian)，因此，也可以用恒流(liu)(liu)放電(dian)測(ce)定其容量。通常，小電(dian)流(liu)(liu)放電(dian)下，5號堿(jian)性電(dian)池容量大約在1800~2000mAh之間。

可充電(dian)(dian)5號電(dian)(dian)池(chi)有鎳(nie)鎘電(dian)(dian)池(chi)和鎳(nie)氫電(dian)(dian)池(chi)，充電(dian)(dian)電(dian)(dian)池(chi)容量單位一般為mAh，偶(ou)爾會采用Ah單位，在(zai)數值上等于放(fang)電(dian)(dian)電(dian)(dian)流與放(fang)電(dian)(dian)時間(jian)的乘積。

5號鎳鎘電池容量：因環保(bao)法規(gui)的(de)(de)限制，鎳鎘電(dian)池(chi)正在(zai)逐漸退出市(shi)場(chang)，但在(zai)某些要求(qiu)低(di)價的(de)(de)場(chang)合鎳鎘電(dian)池(chi)還有一(yi)定的(de)(de)市(shi)場(chang)，5號(hao)鎳鎘電(dian)池(chi)容量一(yi)般為500~700mAh，其中GP、日立、松下的(de)(de)5號(hao)鎳鎘電(dian)池(chi)容量可(ke)以(yi)做的(de)(de)高(gao)一(yi)些。

5號鎳氫電池容量：一般都可(ke)以做到(dao)1200~1300mAh，是5號(hao)鎳(nie)鎘(ge)電(dian)池(chi)容量(liang)(liang)的兩倍，由于鎳(nie)氫電(dian)池(chi)比鎳(nie)鎘(ge)電(dian)池(chi)有許(xu)多工作優(you)勢，而且(qie)又被開發(fa)出新的用途，因此(ci)得以廣泛采用， 5號(hao)鎳(nie)氫電(dian)池(chi)容量(liang)(liang)做的大而穩(wen)的有GP、日系(xi)企(qi)業、國內有科(ke)力(li)遠(yuan)、東(dong)莞鉅大、深圳倍特力(li)等名(ming)企(qi)。但(dan)名(ming)牌鎳(nie)氫電(dian)池(chi)被仿冒的現(xian)象也很普遍(bian)。

鋰(li)離子電(dian)(dian)(dian)池(chi)(chi)(chi)中有(you)一(yi)款14500鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)，因其(qi)外形尺(chi)寸(cun)與其(qi)5號電(dian)(dian)(dian)池(chi)(chi)(chi)接(jie)近，故而也(ye)被冠以5號鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)之名，這種5號電(dian)(dian)(dian)池(chi)(chi)(chi)容量可以設計成500~900mAh，但其(qi)充放(fang)電(dian)(dian)(dian)壽命卻遠超5號鎳(nie)氫(qing)電(dian)(dian)(dian)池(chi)(chi)(chi)。

7號(hao)(hao)電池從(cong)性質上(shang)分，包(bao)括一(yi)次(ci)(ci)7號(hao)(hao)電池和(he)(he)二次(ci)(ci)7號(hao)(hao)電池，7號(hao)(hao)電池容(rong)量(liang)也因此被(bei)分為一(yi)次(ci)(ci)7號(hao)(hao)電池容(rong)量(liang)和(he)(he)二次(ci)(ci)7號(hao)(hao)電池容(rong)量(liang)

可(ke)做成7號外(wai)形的一(yi)次(ci)電(dian)(dian)池(chi)(chi)(chi)(chi)分(fen)為碳性電(dian)(dian)池(chi)(chi)(chi)(chi)和堿(jian)性電(dian)(dian)池(chi)(chi)(chi)(chi)，通常(chang)，它們的放電(dian)(dian)容(rong)量(liang)是(shi)(shi)指從標稱(cheng)電(dian)(dian)壓(ya)（1.5V）放電(dian)(dian)到終止電(dian)(dian)壓(ya)(0.9V)的時(shi)間長度(du)，丈量(liang)方法為恒(heng)阻放電(dian)(dian)，人們常(chang)說的電(dian)(dian)池(chi)(chi)(chi)(chi)放電(dian)(dian)幾分(fen)鐘(zhong)，指的是(shi)(shi)在(zai)3.9Ω放電(dian)(dian)制度(du)下(xia)的容(rong)量(liang)。

7號碳性電池容量：按照IEC標準，碳性(xing)電池(chi)(chi)可以14.8v 2200mah分為三種(zhong)類(lei)型：P型（高(gao)功率電池(chi)(chi)）、C型（高(gao)容量電池(chi)(chi)）和第一代的S型糊式(shi)電池(chi)(chi)。

S型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)曾(ceng)經被淘(tao)汰，在它的(de)基礎上展開出了C型(xing)(xing)紙板電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，后者(zhe)用30~70%的(de)高活性錳替(ti)代了自然錳，而且(qie)正(zheng)極(ji)(ji)填充量進(jin)步了30%，所以(yi)，容量得以(yi)進(jin)步，C型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)多(duo)用于小電(dian)(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)所，如鐘(zhong)表、遙控器(qi)、收音機、手電(dian)(dian)(dian)(dian)(dian)筒等。P型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)正(zheng)極(ji)(ji)全(quan)部采用高活性錳，性能大大提升(sheng)，可用于大電(dian)(dian)(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)(dian)(dian)，如相機、閃光燈，不(bu)過(guo)，由于堿性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)市(shi)場(chang)(chang)占有率起來(lai)越(yue)大，所以(yi)，P型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)往(wang)常也(ye)主要是用于18650 2600mah鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)原C型(xing)(xing)號電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)市(shi)場(chang)(chang)而C型(xing)(xing)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)基本退(tui)出市(shi)場(chang)(chang)。

7號碳性電(dian)(dian)池(chi)容(rong)(rong)量(liang)由于電(dian)(dian)池(chi)消費(fei)廠家配方的(de)不同而有(you)差別，在3.9Ω放電(dian)(dian)制(zhi)度下，普(pu)通(tong)在25~35分(fen)鐘之(zhi)間(jian)(jian)，東(dong)莞(guan)鉅大(da)有(you)一款環保碳性電(dian)(dian)池(chi)，其標稱放電(dian)(dian)時間(jian)(jian)35分(fen)鐘，理論放電(dian)(dian)接近40分(fen)鐘，這是(shi)比較高容(rong)(rong)量(liang)的(de)7號碳性電(dian)(dian)池(chi)。

7號堿性電池容量：在(zai)(zai)3.9Ω放(fang)電(dian)(dian)方式下，7號堿性(xing)(xing)電(dian)(dian)池(chi)容(rong)量(liang)普通可以抵達7號碳性(xing)(xing)電(dian)(dian)池(chi)容(rong)量(liang)的4~5倍，在(zai)(zai)數值表現上(shang)，為(wei)放(fang)電(dian)(dian)時間(jian)(jian)(jian)的延長，東莞鉅大該型號電(dian)(dian)池(chi)放(fang)電(dian)(dian)時間(jian)(jian)(jian)為(wei)2.6小(xiao)時。同時，堿性(xing)(xing)電(dian)(dian)池(chi)的結構(gou)特性(xing)(xing)更(geng)耐受大電(dian)(dian)流放(fang)電(dian)(dian)，因而，該款電(dian)(dian)池(chi)用500mAh電(dian)(dian)流放(fang)電(dian)(dian)時間(jian)(jian)(jian)約為(wei)55分鐘，假定改(gai)用小(xiao)電(dian)(dian)流放(fang)電(dian)(dian)，則這款7號電(dian)(dian)池(chi)容(rong)量(liang)大約在(zai)(zai)800~1200mAh之間(jian)(jian)(jian)。

可做成7號外形的(de)(de)二次電池(chi)(chi)有(you)鎳鎘電池(chi)(chi)和(he)鎳氫電池(chi)(chi)，二次電池(chi)(chi)的(de)(de)容(rong)量單位為mAh，或者Ah，表示在某一(yi)個放電電流下的(de)(de)耐用(yong)時間。

7號鎳鎘電池容量：其標稱(cheng)電(dian)壓為了1.2V，終(zhong)止電(dian)壓用8小時(shi)率(lv)放電(dian)為1.1V，10ah電(dian)池(chi)在(zai)這(zhe)一(yi)條件下(xia)，鎳鎘電(dian)池(chi)的設(she)計容量(liang)在(zai)500mAh以內，但(dan)鎘污染環(huan)境，而(er)且在(zai)充放電(dian)一(yi)定次數后電(dian)量(liang)會降(jiang)落到80%，壽命比同類型鎳氫(qing)少(shao)，因此，正被(bei)鎳氫(qing)電(dian)池(chi)全面(mian)取代(dai)而(er)退出市場。

7號鎳氫電池容量：鎳氫(qing)電(dian)池的標稱電(dian)壓為1.2V，終止(zhi)電(dian)壓為1.0V，主流7號鎳氫(qing)電(dian)池容量可以抵達650~800mAh。

由(you)于鎳(nie)氫電池(chi)占領了鎳(nie)鎘電池(chi)的原有市(shi)場(chang)，而(er)又有自己(ji)的新市(shi)場(chang)故而(er)成為市(shi)場(chang)新寵，難免呈現一(yi)些(xie)非(fei)理性行(xing)為，7號電池(chi)容(rong)量虛(xu)標現象就(jiu)是其一(yi)。目前，國內做到800mAh曾經相當不(bu)錯了，假定(ding)遇(yu)到標注1000mAh以上的有可(ke)能就(jiu)是虛(xu)標了。由(you)于7號鎳(nie)氫電池(chi)容(rong)量最終是由(you)其材質所決議(yi)的。
