【干電池容量】5號(hao)干電池容量 7號(hao)干電池容量

5號電池劃分為一次電池和二次電池，因此，5號(hao)電(dian)池容量可(ke)分為可(ke)充5號(hao)電(dian)池容量與不可(ke)充5號(hao)電(dian)池容量。

不可(ke)充5號(hao)電(dian)(dian)(dian)(dian)池(chi)又分為碳性(xing)和(he)堿性(xing)電(dian)(dian)(dian)(dian)池(chi)，通常，不可(ke)充5號(hao)電(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)的計算方(fang)法為：以3.9Ω恒阻(zu)放電(dian)(dian)(dian)(dian)由工作電(dian)(dian)(dian)(dian)壓(ya)（1.5V）下降(jiang)到終止電(dian)(dian)(dian)(dian)壓(ya)（0.9V）時(shi)的時(shi)間長度(du)。

5號碳性電池容量：目前(qian)，市面(mian)上的5號(hao)碳(tan)性電(dian)池通常(chang)都是高功率的P型電(dian)池， 5號(hao)碳(tan)性電(dian)池容量(liang)一般在放電(dian)55分鐘以上，但因(yin)不同的廠家設計而有所不同，東莞鉅大(da)一款開路電(dian)壓為1.65V的碳(tan)性電(dian)池可以放電(dian)90分鐘，是業內容量(liang)比較(jiao)高容量(liang)的5號(hao)碳(tan)性電(dian)池。

5號堿性電池容量：一般(ban)情(qing)況下(xia)，3.9Ω放電(dian)可(ke)達6個小時(shi)以(yi)上(shang)，因為堿性電(dian)池(chi)可(ke)以(yi)用大電(dian)流放電(dian)，因此，也可(ke)以(yi)用恒流放電(dian)測定(ding)其容量。通常，小電(dian)流放電(dian)下(xia)，5號堿性電(dian)池(chi)容量大約在1800~2000mAh之(zhi)間。

可充電(dian)(dian)5號電(dian)(dian)池有鎳鎘(ge)電(dian)(dian)池和鎳氫(qing)電(dian)(dian)池，充電(dian)(dian)電(dian)(dian)池容量單位(wei)一般為mAh，偶爾會采(cai)用Ah單位(wei)，在(zai)數值上等于(yu)放(fang)電(dian)(dian)電(dian)(dian)流與放(fang)電(dian)(dian)時(shi)間的乘積。

5號鎳鎘電池容量：因環保法(fa)規(gui)的限制，鎳(nie)鎘電池正(zheng)在逐漸(jian)退(tui)出市(shi)(shi)場，但在某些(xie)要求低價(jia)的場合鎳(nie)鎘電池還有一(yi)定的市(shi)(shi)場，5號鎳(nie)鎘電池容(rong)量(liang)一(yi)般為500~700mAh，其(qi)中(zhong)GP、日(ri)立、松下的5號鎳(nie)鎘電池容(rong)量(liang)可(ke)以做(zuo)的高一(yi)些(xie)。

5號鎳氫電池容量：一般都可(ke)以做(zuo)到(dao)1200~1300mAh，是5號(hao)鎳(nie)(nie)鎘電(dian)池容量的(de)兩倍，由于鎳(nie)(nie)氫(qing)電(dian)池比鎳(nie)(nie)鎘電(dian)池有(you)許多(duo)工作優勢，而且又(you)被(bei)(bei)開發出新(xin)的(de)用途(tu)，因此得以廣泛(fan)采用， 5號(hao)鎳(nie)(nie)氫(qing)電(dian)池容量做(zuo)的(de)大(da)而穩(wen)的(de)有(you)GP、日系(xi)企(qi)業、國內有(you)科力遠、東莞鉅(ju)大(da)、深圳倍特力等名企(qi)。但名牌鎳(nie)(nie)氫(qing)電(dian)池被(bei)(bei)仿冒的(de)現象也(ye)很普遍。

鋰離子電(dian)池中有一款14500鋰電(dian)池，因其(qi)(qi)外形(xing)尺寸與(yu)其(qi)(qi)5號(hao)電(dian)池接(jie)近，故而(er)也被冠以5號(hao)鋰電(dian)池之名(ming)，這種5號(hao)電(dian)池容量(liang)可以設計成500~900mAh，但其(qi)(qi)充放電(dian)壽命卻遠超5號(hao)鎳氫(qing)電(dian)池。

7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)從性質上分，包括一次(ci)(ci)7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)和(he)(he)二次(ci)(ci)7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)也因此(ci)被分為一次(ci)(ci)7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)和(he)(he)二次(ci)(ci)7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)容量(liang)

可做成7號外形(xing)的(de)一次(ci)電(dian)(dian)(dian)池(chi)(chi)分為碳性電(dian)(dian)(dian)池(chi)(chi)和(he)堿性電(dian)(dian)(dian)池(chi)(chi)，通常，它們的(de)放電(dian)(dian)(dian)容量是(shi)指(zhi)從(cong)標稱電(dian)(dian)(dian)壓(ya)（1.5V）放電(dian)(dian)(dian)到終止電(dian)(dian)(dian)壓(ya)(0.9V)的(de)時間(jian)長(chang)度，丈量方(fang)法為恒阻放電(dian)(dian)(dian)，人們常說的(de)電(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)幾(ji)分鐘，指(zhi)的(de)是(shi)在3.9Ω放電(dian)(dian)(dian)制度下的(de)容量。

7號碳性電池容量：按(an)照IEC標準，碳性電(dian)池(chi)可(ke)以14.8v 2200mah分(fen)為(wei)三種(zhong)類型(xing)：P型(xing)（高(gao)功率(lv)電(dian)池(chi)）、C型(xing)（高(gao)容量(liang)電(dian)池(chi)）和第一代的S型(xing)糊式電(dian)池(chi)。

S型電(dian)(dian)(dian)(dian)(dian)池(chi)曾經被淘汰，在它的基(ji)礎上展開出了C型紙板電(dian)(dian)(dian)(dian)(dian)池(chi)，后(hou)者用30~70%的高活性錳替代了自然(ran)錳，而且正極填充量進步了30%，所(suo)以(yi)，容(rong)量得以(yi)進步，C型電(dian)(dian)(dian)(dian)(dian)池(chi)多用于小(xiao)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)所(suo)，如鐘(zhong)表、遙控器、收音機(ji)、手電(dian)(dian)(dian)(dian)(dian)筒等。P型電(dian)(dian)(dian)(dian)(dian)池(chi)正極全部(bu)采(cai)用高活性錳，性能大(da)大(da)提升，可(ke)用于大(da)電(dian)(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)(dian)，如相機(ji)、閃光燈，不過，由于堿性電(dian)(dian)(dian)(dian)(dian)池(chi)的市(shi)場(chang)(chang)占有率(lv)起來越大(da)，所(suo)以(yi)，P型電(dian)(dian)(dian)(dian)(dian)池(chi)往(wang)常也(ye)主要是用于18650 2600mah鋰電(dian)(dian)(dian)(dian)(dian)池(chi)原C型號電(dian)(dian)(dian)(dian)(dian)池(chi)的市(shi)場(chang)(chang)而C型電(dian)(dian)(dian)(dian)(dian)池(chi)基(ji)本退出市(shi)場(chang)(chang)。

7號碳(tan)性電(dian)池容量(liang)由于電(dian)池消費廠家配方的(de)不同而有(you)差別，在3.9Ω放電(dian)制(zhi)度下，普通在25~35分(fen)鐘之(zhi)間，東(dong)莞鉅(ju)大(da)有(you)一款環保碳(tan)性電(dian)池，其標稱放電(dian)時間35分(fen)鐘，理論放電(dian)接近40分(fen)鐘，這(zhe)是比較高(gao)容量(liang)的(de)7號碳(tan)性電(dian)池。

7號堿性電池容量：在(zai)3.9Ω放(fang)電(dian)方式下，7號堿性(xing)電(dian)池(chi)(chi)容量普通可以抵達7號碳(tan)性(xing)電(dian)池(chi)(chi)容量的4~5倍，在(zai)數值表(biao)現上，為放(fang)電(dian)時(shi)間(jian)的延(yan)長，東莞鉅(ju)大該型號電(dian)池(chi)(chi)放(fang)電(dian)時(shi)間(jian)為2.6小時(shi)。同時(shi)，堿性(xing)電(dian)池(chi)(chi)的結構特性(xing)更(geng)耐受大電(dian)流(liu)放(fang)電(dian)，因而，該款(kuan)電(dian)池(chi)(chi)用500mAh電(dian)流(liu)放(fang)電(dian)時(shi)間(jian)約為55分(fen)鐘，假(jia)定(ding)改用小電(dian)流(liu)放(fang)電(dian)，則(ze)這款(kuan)7號電(dian)池(chi)(chi)容量大約在(zai)800~1200mAh之間(jian)。

可(ke)做成7號外形的二次電(dian)(dian)池有鎳鎘電(dian)(dian)池和鎳氫電(dian)(dian)池，二次電(dian)(dian)池的容量(liang)單位為mAh，或者Ah，表示在某一(yi)個放電(dian)(dian)電(dian)(dian)流下(xia)的耐用(yong)時間(jian)。

7號鎳鎘電池容量：其標稱電(dian)(dian)壓為了1.2V，終止電(dian)(dian)壓用8小(xiao)時率放(fang)電(dian)(dian)為1.1V，10ah電(dian)(dian)池在(zai)這一條件下，鎳(nie)(nie)鎘(ge)電(dian)(dian)池的設計(ji)容(rong)量在(zai)500mAh以內，但鎘(ge)污染環境，而且在(zai)充放(fang)電(dian)(dian)一定次數后電(dian)(dian)量會(hui)降落(luo)到80%，壽命比同類型鎳(nie)(nie)氫少，因(yin)此(ci)，正(zheng)被鎳(nie)(nie)氫電(dian)(dian)池全面取(qu)代而退出市場。

7號鎳氫電池容量：鎳氫電池的標稱(cheng)電壓為(wei)1.2V，終(zhong)止電壓為(wei)1.0V，主(zhu)流7號鎳氫電池容量(liang)可以抵達650~800mAh。

由于鎳氫(qing)電池占領了鎳鎘(ge)電池的原(yuan)有(you)(you)市(shi)(shi)場，而(er)又有(you)(you)自己的新市(shi)(shi)場故而(er)成為(wei)市(shi)(shi)場新寵(chong)，難免呈現一些非理性行為(wei)，7號電池容量虛標現象就(jiu)是其一。目(mu)前(qian)，國內做(zuo)到(dao)800mAh曾經相當不錯了，假定(ding)遇到(dao)標注1000mAh以上的有(you)(you)可能就(jiu)是虛標了。由于7號鎳氫(qing)電池容量最終是由其材(cai)質所(suo)決(jue)議的。
