數(shu)碼相(xiang)(xiang)機的(de)(de)迅(xun)速(su)普及(ji)在無形中也帶(dai)動了鎳氫(qing)(qing)充電(dian)電(dian)池(chi)的(de)(de)高速(su)發展。由于數(shu)碼相(xiang)(xiang)機的(de)(de)工(gong)作(zuo)電(dian)流普遍(bian)較大(da)，也比(bi)較耗電(dian)，普通的(de)(de)堿(jian)性(xing)電(dian)池(chi)已經難以長時間勝任(ren)數(shu)碼相(xiang)(xiang)機的(de)(de)動力之源。而鎳氫(qing)(qing)充電(dian)電(dian)池(chi)不但容量較大(da)，還能提供較大(da)的(de)(de)工(gong)作(zuo)電(dian)流，又能重復使用且環保，自(zi)然而然地成為了大(da)部分數(shu)碼相(xiang)(xiang)機玩(wan)家(jia)首選的(de)(de)能源。

　　綜觀鎳氫電池市場，與原裝充電器搭配銷售的套裝電池工作穩定，但價格較高，因此不少玩家都把目光瞄準了價格相對較低的零售電池或價格更為便宜的工業包裝電池--這些電池都沒有充電器搭配銷售。另外，一部分玩家電池使用量較大，一個充電器已經不能滿足日常需求，所以另行購買電池充電器是必要的。因而如何去選擇讓自己滿意的鎳氫電池充電器便成了重要的事情。

　　劣質(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)(de)危(wei)害(hai)(hai)： 一(yi)(yi)個充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)(de)價(jia)(jia)格(ge)一(yi)(yi)般(ban)都在(zai)幾十元到數百元之(zhi)間，比(bi)起數碼相機的(de)(de)(de)(de)(de)價(jia)(jia)格(ge)來說真(zhen)是顯得(de)有些微不足(zu)道。但(dan)這個小小的(de)(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)如(ru)果質(zhi)量(liang)(liang)不過(guo)關(guan)的(de)(de)(de)(de)(de)話，給(gei)用(yong)戶帶來的(de)(de)(de)(de)(de)危(wei)害(hai)(hai)卻(que)不小。首先，劣質(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)由于配件質(zhi)量(liang)(liang)不過(guo)關(guan)或(huo)電(dian)(dian)(dian)(dian)氣性能不良，自身容易出現短路、過(guo)熱燒毀等(deng)(deng)故障，輕(qing)則(ze)讓(rang)用(yong)戶損失充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，重則(ze)會引起各種(zhong)災(zai)難性的(de)(de)(de)(de)(de)危(wei)害(hai)(hai)如(ru)火(huo)災(zai)等(deng)(deng)；其次，劣質(zhi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)由于輸出電(dian)(dian)(dian)(dian)流不穩定或(huo)不符合規格(ge)，會引起電(dian)(dian)(dian)(dian)池(chi)過(guo)熱、充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)不完全等(deng)(deng)故障，輕(qing)則(ze)影響使用(yong)，重則(ze)會引起電(dian)(dian)(dian)(dian)池(chi)爆炸等(deng)(deng)危(wei)險。由此看來，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)質(zhi)量(liang)(liang)的(de)(de)(de)(de)(de)好壞的(de)(de)(de)(de)(de)確要(yao)引起消費者的(de)(de)(de)(de)(de)注意。作(zuo)一(yi)(yi)個形象的(de)(de)(de)(de)(de)比(bi)喻(yu)，電(dian)(dian)(dian)(dian)池(chi)好比(bi)戰場上的(de)(de)(de)(de)(de)士兵，而(er)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)就好比(bi)后勤部(bu)隊--要(yao)讓(rang)士兵在(zai)火(huo)線上隨時保(bao)持良好的(de)(de)(de)(de)(de)戰斗狀(zhuang)態，后勤部(bu)隊至(zhi)關(guan)重要(yao)。下面就讓(rang)我們一(yi)(yi)步(bu)步(bu)來選購充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)。

　　充電器的分類(lei)：充電(dian)(dian)器(qi)通(tong)常按充電(dian)(dian)時間(jian)來分類(lei)，有"快(kuai)速(su)充電(dian)(dian)器(qi)（以下簡稱快(kuai)充）"和"慢(man)速(su)充電(dian)(dian)器(qi)（以下簡稱慢(man)充）"兩種。鎳氫電(dian)(dian)池(chi)的充電(dian)(dian)時間(jian)基本上可(ke)按下列公(gong)式計算：充電(dian)(dian)時間(jian)（小時）≈效(xiao)率系(xi)數(shu)(shu)×容量(liang)（mAh）÷充電(dian)(dian)電(dian)(dian)流(mA) 注：效(xiao)率系(xi)數(shu)(shu)為1.2～1.5之間(jian)的一個不定(ding)數(shu)(shu)，因不同充電(dian)(dian)器(qi)而異。

　　慢充(chong)一般采用(yong)(yong)恒流(liu)(liu)方(fang)式(shi)充(chong)電(dian)(dian)(dian)(dian)，且在電(dian)(dian)(dian)(dian)池充(chong)滿后自動(dong)轉為(wei)涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)狀態(tai)。慢充(chong)的優點是(shi)電(dian)(dian)(dian)(dian)路設計簡單，易于(yu)實現，價格也(ye)較(jiao)低(di);由(you)于(yu)采用(yong)(yong)小電(dian)(dian)(dian)(dian)流(liu)(liu)恒流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)，有(you)效地(di)降低(di)了(le)電(dian)(dian)(dian)(dian)池在充(chong)電(dian)(dian)(dian)(dian)過程中的發熱量，對延長(chang)電(dian)(dian)(dian)(dian)池的使用(yong)(yong)壽命很有(you)好處。缺點就是(shi)充(chong)電(dian)(dian)(dian)(dian)時間太長(chang),特別(bie)是(shi)電(dian)(dian)(dian)(dian)池數量較(jiao)多的情況下有(you)點力不從心。

　　快充(chong)一般都采(cai)用脈沖大電(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)，但(dan)由于電(dian)(dian)(dian)池在大電(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)過程(cheng)中會產生極化(hua)反(fan)應，導致(zhi)電(dian)(dian)(dian)池溫度迅速升高(gao)，充(chong)滿(man)后若(ruo)再繼續加電(dian)(dian)(dian)就有可能(neng)發生爆炸和燃燒，所以(yi)快充(chong)還采(cai)用專用芯片(pian)來(lai)控制充(chong)電(dian)(dian)(dian)過程(cheng)，實時監控電(dian)(dian)(dian)池電(dian)(dian)(dian)量(liang)，一旦充(chong)滿(man)就自動停(ting)止充(chong)電(dian)(dian)(dian)，使整個充(chong)電(dian)(dian)(dian)過程(cheng)變得(de)安全(quan)、高(gao)效。快充(chong)適合電(dian)(dian)(dian)池數(shu)量(liang)較(jiao)多或心急的玩家。缺點便是(shi)無(wu)法避免的大發熱(re)量(liang)，對電(dian)(dian)(dian)池壽命有一定的影響.價格也(ye)比慢充(chong)貴一些。

　　類型：前文提到的快充和慢充，也是挑選充電器的(de)(de)(de)(de)(de)(de)一個(ge)重要(yao)標(biao)準(zhun)。兩(liang)者比(bi)較起(qi)來(lai)，快(kuai)充(chong)(chong)的(de)(de)(de)(de)(de)(de)缺點是(shi)對電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)(de)壽命有(you)所(suo)影響以及價格(ge)較高。不過(guo)在(zai)(zai)(zai)這(zhe)個(ge)效率至上的(de)(de)(de)(de)(de)(de)時(shi)代，快(kuai)充(chong)(chong)的(de)(de)(de)(de)(de)(de)流行趨勢越(yue)來(lai)越(yue)明顯，因(yin)為(wei)使用(yong)快(kuai)充(chong)(chong)所(suo)節省的(de)(de)(de)(de)(de)(de)時(shi)間遠比(bi)電(dian)(dian)(dian)池所(suo)減少的(de)(de)(de)(de)(de)(de)壽命來(lai)得(de)重要(yao)。況且現在(zai)(zai)(zai)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)(de)價格(ge)也越(yue)來(lai)越(yue)低，所(suo)以在(zai)(zai)(zai)資金允(yun)許的(de)(de)(de)(de)(de)(de)情況下，最好選擇快(kuai)充(chong)(chong)。 （質量較差(cha)的(de)(de)(de)(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)器內部構造極為(wei)簡單(dan)，電(dian)(dian)(dian)路板(ban)的(de)(de)(de)(de)(de)(de)工藝(yi)更(geng)是(shi)糟糕，因(yin)此如(ru)果是(shi)買(mai)非(fei)名牌充(chong)(chong)電(dian)(dian)(dian)器的(de)(de)(de)(de)(de)(de)話，開(kai)蓋看看還是(shi)有(you)必要(yao)的(de)(de)(de)(de)(de)(de)）

　　外觀(guan)(guan)及內在(zai)(zai)(zai)品(pin)質(zhi)：優秀的(de)(de)(de)做工在(zai)(zai)(zai)很大程(cheng)度(du)上(shang)(shang)也(ye)是廠商實(shi)力的(de)(de)(de)體(ti)現，而用(yong)料(liao)(liao)的(de)(de)(de)質(zhi)量(liang)(liang)(liang)(liang)則(ze)是安全(quan)使用(yong)的(de)(de)(de)保障。我們在(zai)(zai)(zai)購買(mai)時(shi)，可(ke)注意一(yi)下(xia)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)外觀(guan)(guan)的(de)(de)(de)光澤度(du)、邊角和小地方(fang)的(de)(de)(de)精(jing)細程(cheng)度(du)；掂(dian)掂(dian)分量(liang)(liang)(liang)(liang)做一(yi)下(xia)比較，一(yi)般來說同(tong)類(lei)型(xing)產品(pin)偷工減料(liao)(liao)者重(zhong)量(liang)(liang)(liang)(liang)相對較輕。須要(yao)注意的(de)(de)(de)是，快充(chong)(chong)由于使用(yong)了(le)控制芯片(pian)以及開關電(dian)(dian)(dian)(dian)源|穩(wen)壓(ya)器(qi)(qi)，重(zhong)量(liang)(liang)(liang)(liang)有可(ke)能(neng)(neng)(neng)會比慢充(chong)(chong)輕，所以掂(dian)重(zhong)量(liang)(liang)(liang)(liang)這種差(cha)別方(fang)法最適(shi)合(he)于同(tong)一(yi)類(lei)型(xing)的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)。在(zai)(zai)(zai)條件允許的(de)(de)(de)情況下(xia)可(ke)以要(yao)求商家將(jiang)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)打開觀(guan)(guan)看內部結構，看看內部電(dian)(dian)(dian)(dian)路板(ban)電(dian)(dian)(dian)(dian)子元(yuan)件的(de)(de)(de)排列、焊接工藝(yi)等方(fang)面(mian)，以確保貨真價(jia)實(shi)。另外,最好將(jiang)自己使用(yong)的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)帶上(shang)(shang)，在(zai)(zai)(zai)商家處(chu)充(chong)(chong)電(dian)(dian)(dian)(dian)30分鐘左(zuo)右,觀(guan)(guan)察一(yi)下(xia)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)發熱量(liang)(liang)(liang)(liang)--質(zhi)量(liang)(liang)(liang)(liang)好的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)能(neng)(neng)(neng)夠有效地控制發熱量(liang)(liang)(liang)(liang),而劣質(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)則(ze)有可(ke)能(neng)(neng)(neng)將(jiang)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)得滾燙(tang)--這種現象特別容易出現在(zai)(zai)(zai)劣質(zhi)快充(chong)(chong)上(shang)(shang)。這樣(yang)的(de)(de)(de)產品(pin)一(yi)定不能(neng)(neng)(neng)購買(mai)。

　　易用(yong)性：為了日后使(shi)用(yong)更加方便(bian)，在選擇充電器時(shi)最好多考慮一下產品的(de)易用(yong)性。

　　有的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器只能為AA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而有些(xie)(xie)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器不(bu)(bu)(bu)但(dan)能充(chong)(chong)(chong)(chong)AA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，還(huan)可(ke)(ke)以(yi)(yi)為AAA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，如(ru)果有多(duo)種型號(hao)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，可(ke)(ke)以(yi)(yi)選(xuan)擇(ze)這種充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。 常(chang)見(jian)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器一(yi)般可(ke)(ke)以(yi)(yi)同時(shi)(shi)為4節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，手中的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)比較多(duo)，同時(shi)(shi)又(you)不(bu)(bu)(bu)愿意為大量電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)而長時(shi)(shi)間等(deng)(deng)待的(de)(de)用(yong)戶，可(ke)(ke)以(yi)(yi)選(xuan)擇(ze)有6個(ge)(ge)或8個(ge)(ge)甚至(zhi)更多(duo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)插槽(cao)的(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，當(dang)然，這類(lei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)體積會大一(yi)些(xie)(xie)，不(bu)(bu)(bu)便(bian)攜帶，價(jia)格也(ye)自然會高一(yi)些(xie)(xie)。 很(hen)多(duo)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器由(you)(you)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)設計(ji)的(de)(de)關系,只能為偶數(shu)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)如(ru)2節(jie)、4節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)成對地(di)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這對于(yu)某些(xie)(xie)使(shi)用(yong)單個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)用(yong)戶來說(shuo)很(hen)不(bu)(bu)(bu)方便(bian)，于(yu)是市場有一(yi)些(xie)(xie)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)設計(ji)時(shi)(shi)考慮到(dao)了這一(yi)問(wen)題，它們可(ke)(ke)以(yi)(yi)為1節(jie)、3節(jie)等(deng)(deng)奇數(shu)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。在(zai)購買時(shi)(shi)建議選(xuan)擇(ze)這類(lei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，以(yi)(yi)便(bian)日后的(de)(de)使(shi)用(yong)。由(you)(you)于(yu)鎳(nie)(nie)氫和鎳(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)結構相近，所(suo)以(yi)(yi)有的(de)(de)鎳(nie)(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器在(zai)設計(ji)時(shi)(shi)還(huan)考慮到(dao)了對鎳(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)兼容，如(ru)果想(xiang)讓手中的(de)(de)老電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)再次(ci)煥發青(qing)春，這類(lei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器倒是一(yi)個(ge)(ge)不(bu)(bu)(bu)錯的(de)(de)選(xuan)擇(ze)。

　　除此以外,還有一個小地方要提醒大家注意，有的充電器為方(fang)便(bian)攜帶，將插(cha)頭(tou)與機身(shen)做在了(le)(le)一起，不過在使用時(shi)往往會在多用插(cha)線板上(shang)占去兩(liang)個(ge)甚(shen)至更(geng)多插(cha)座的(de)位置(zhi)，對于插(cha)座比較集中(zhong)的(de)朋友來說，充(chong)電(dian)時(shi)就(jiu)不得不把其他(ta)的(de)插(cha)頭(tou)拔掉，很不方(fang)便(bian)。如(ru)果不想為充(chong)電(dian)器(qi)另行(xing)購買一個(ge)插(cha)線板的(de)話，就(jiu)應該選擇非(fei)一體式(shi)的(de)充(chong)電(dian)器(qi)了(le)(le)。
