干電池：這是使用最普遍的(de)(de)(de)電池類(lei)型之一(yi)，很(hen)多(duo)人用過(guo)干電池，但了(le)解其構造的(de)(de)(de)人卻不多(duo)。一(yi)般我們常(chang)用的(de)(de)(de)干電池又稱為(wei)鋅(xin)(xin)錳電池。可分為(wei)碳鋅(xin)(xin)電池（Carbon-Zinc）和氯(lv)化鋅(xin)(xin)電池（Zinc-Chloride），其優點是能(neng)量(liang)密(mi)度較高(gao)，電流密(mi)度適當，易實現機械化生產等。在大(da)(da)賣場中(zhong)這兩(liang)類(lei)電池被成盒成盒的(de)(de)(de)以低(di)廉的(de)(de)(de)售價拍賣著。但很(hen)可惜的(de)(de)(de)由(you)于(yu)能(neng)量(liang)密(mi)度不足，一(yi)般這種電池只用于(yu)耗電量(liang)較小的(de)(de)(de)電子產品，如：鬧鐘(zhong)，計算(suan)(suan)器等。如果你(ni)打(da)算(suan)(suan)用他來驅動(dong)你(ni)的(de)(de)(de)數(shu)碼相(xiang)機恐怕你(ni)會大(da)(da)失所望。

堿性鋅-錳電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)（Zinc-MnO2）：是干(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)中(zhong)的(de)(de)(de)一(yi)(yi)(yi)個(ge)重要(yao)角色(se)。這一(yi)(yi)(yi)類的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)就是我(wo)們常(chang)稱的(de)(de)(de)“堿性電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)”，由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容量大(da)，電(dian)(dian)(dian)(dian)(dian)(dian)流強使用上(shang)又(you)持久，市場上(shang)對此類電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)需求越來(lai)越高。然而，部分廠商的(de)(de)(de)堿性電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)為(wei)(wei)非(fei)環保的(de)(de)(de)含汞(gong)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，原因(yin)(yin)是此類電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)如在成份中(zhong)加入氧化銀可提升其電(dian)(dian)(dian)(dian)(dian)(dian)容量約30%以(yi)上(shang)，但同時零售價格也(ye)(ye)相(xiang)對提高。迄今為(wei)(wei)止(zhi)，堿性電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是最成功的(de)(de)(de)高容量電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，也(ye)(ye)是目前最具性能(neng)(neng)價格比的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)之一(yi)(yi)(yi)，它(ta)改變了傳統電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)內部結構和(he)電(dian)(dian)(dian)(dian)(dian)(dian)化學系統，同過(guo)采用極(ji)純凈極(ji)活躍的(de)(de)(de)正負極(ji)材料，它(ta)的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)容量達到了普(pu)通干(gan)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)5-7倍，存(cun)儲壽命也(ye)(ye)超過(guo)了普(pu)通電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)兩(liang)倍。另一(yi)(yi)(yi)方面(mian)，堿性電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也(ye)(ye)因(yin)(yin)為(wei)(wei)它(ta)完美的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)曲線而倍受(shou)青睞，特別適用于(yu)需要(yao)持續(xu)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)流放電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)場合，如相(xiang)機，電(dian)(dian)(dian)(dian)(dian)(dian)動玩具，BP機，WALKMAN，電(dian)(dian)(dian)(dian)(dian)(dian)動剔(ti)須(xu)刀等市場上(shang)性能(neng)(neng)良好(hao)又(you)經濟實惠的(de)(de)(de)堿性電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)有(you)南孚、雙(shuang)鹿等品牌。

干電池的選購常識

市場上銷售的鋅(xin)錳(meng)電池(chi)(chi)有堿性鋅(xin)錳(meng)電池(chi)(chi)和(he)普通高(gao)功率紙板鋅(xin)錳(meng)電池(chi)(chi)。

圓筒(tong)型(xing)(xing)鋅(xin)(xin)錳(meng)電(dian)池(chi)(chi)因隔離物的(de)(de)區(qu)別可(ke)分為糊式(shi)鋅(xin)(xin)錳(meng)電(dian)池(chi)(chi)和紙(zhi)板(ban)(ban)鋅(xin)(xin)錳(meng)電(dian)池(chi)(chi)。其中紙(zhi)板(ban)(ban)鋅(xin)(xin)錳(meng)電(dian)池(chi)(chi)因配方組(zu)成的(de)(de)差異(yi)引(yin)起電(dian)性(xing)能的(de)(de)不同，又(you)分為C型(xing)(xing)紙(zhi)板(ban)(ban)電(dian)池(chi)(chi)，也稱為高容量電(dian)池(chi)(chi)；P型(xing)(xing)紙(zhi)板(ban)(ban)電(dian)池(chi)(chi)，又(you)稱為高功率電(dian)池(chi)(chi)。

高(gao)功率紙板(ban)(ban)(ban)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池，如：R6P，電(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)量較(jiao)大，防漏(lou)液(ye)性(xing)(xing)(xing)能(neng)(neng)好，且可(ke)大電(dian)(dian)(dian)(dian)(dian)流連續放電(dian)(dian)(dian)(dian)(dian)。高(gao)功率紙板(ban)(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池價(jia)格便(bian)(bian)宜(yi)（目前(qian)市場售價(jia)0.8~1.5元左右(you)），使用(yong)小(xiao)型鬧鐘或計算器等可(ke)考慮(lv)紙板(ban)(ban)(ban)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池中比(bi)(bi)(bi)較(jiao)平價(jia)的牌子，操作費用(yong)更(geng)經(jing)濟，考慮(lv)耐用(yong)和方便(bian)(bian)程度則需消費者自己選擇。高(gao)能(neng)(neng)堿性(xing)(xing)(xing)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池，如：LR6等，電(dian)(dian)(dian)(dian)(dian)極結(jie)構與(yu)紙板(ban)(ban)(ban)電(dian)(dian)(dian)(dian)(dian)池等相(xiang)反(fan)，外(wai)殼(ke)是鍍鎳鋼殼(ke)，不參與(yu)電(dian)(dian)(dian)(dian)(dian)化學(xue)反(fan)應，因(yin)此不易發生漏(lou)液(ye)。堿性(xing)(xing)(xing)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池壽(shou)命(ming)一般比(bi)(bi)(bi)較(jiao)長，高(gao)耗電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)器例如閃光(guang)燈、相(xiang)機及玩具之類采用(yong)堿性(xing)(xing)(xing)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池可(ke)使用(yong)較(jiao)長時間，比(bi)(bi)(bi)較(jiao)合算，如到外(wai)地旅(lv)游時最好攜帶(dai)堿性(xing)(xing)(xing)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池，因(yin)為使用(yong)堿性(xing)(xing)(xing)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)(dian)池。

注意電池(chi)的(de)性(xing)能(neng)價格比，不(bu)要盲目迷信(xin)洋(yang)品(pin)(pin)牌。事實(shi)上，不(bu)少國產(chan)名牌電池(chi)的(de)性(xing)能(neng)價格比都高于國外同類產(chan)品(pin)(pin)。

注意電池的儲存期。普通鋅錳電池保質期為2年(nian)。購買時應選擇近期生產的產品。
