　　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)(zhi)充(chong)電(dian)器(qi)(qi)的(de)危害(hai)： 一(yi)(yi)個充(chong)電(dian)器(qi)(qi)的(de)價格一(yi)(yi)般都在幾十(shi)元(yuan)到數百元(yuan)之間，比起(qi)(qi)數碼相機的(de)價格來(lai)(lai)說(shuo)真(zhen)是(shi)顯得有些(xie)微不(bu)(bu)足道。但這個小小的(de)充(chong)電(dian)器(qi)(qi)如(ru)果質(zhi)(zhi)量(liang)不(bu)(bu)過關的(de)話，給(gei)用(yong)戶帶(dai)來(lai)(lai)的(de)危害(hai)卻(que)不(bu)(bu)小。首先，劣質(zhi)(zhi)充(chong)電(dian)器(qi)(qi)由于配(pei)件(jian)質(zhi)(zhi)量(liang)不(bu)(bu)過關或電(dian)氣性(xing)能(neng)不(bu)(bu)良，自身容易出現短路、過熱燒(shao)毀等(deng)故(gu)障，輕則(ze)讓用(yong)戶損失(shi)充(chong)電(dian)器(qi)(qi)，重則(ze)會(hui)引起(qi)(qi)各種災難性(xing)的(de)危害(hai)如(ru)火災等(deng)；其次，劣質(zhi)(zhi)充(chong)電(dian)器(qi)(qi)由于輸(shu)出電(dian)流不(bu)(bu)穩定或不(bu)(bu)符(fu)合規(gui)格，會(hui)引起(qi)(qi)電(dian)池過熱、充(chong)電(dian)不(bu)(bu)完全等(deng)故(gu)障，輕則(ze)影響使用(yong)，重則(ze)會(hui)引起(qi)(qi)電(dian)池爆炸等(deng)危險。由此看(kan)來(lai)(lai)，充(chong)電(dian)器(qi)(qi)質(zhi)(zhi)量(liang)的(de)好壞的(de)確要(yao)引起(qi)(qi)消費(fei)者(zhe)的(de)注意。作一(yi)(yi)個形(xing)象的(de)比喻，電(dian)池好比戰(zhan)場上的(de)士兵，而充(chong)電(dian)器(qi)(qi)就好比后勤部隊--要(yao)讓士兵在火線上隨時保持良好的(de)戰(zhan)斗狀態(tai)，后勤部隊至關重要(yao)。下面(mian)就讓我(wo)們(men)一(yi)(yi)步(bu)步(bu)來(lai)(lai)選(xuan)購充(chong)電(dian)器(qi)(qi)。

　　充電器的(de)分類(lei)：充(chong)(chong)電(dian)(dian)器通常按充(chong)(chong)電(dian)(dian)時(shi)間(jian)(jian)來分類(lei)，有(you)"快速充(chong)(chong)電(dian)(dian)器（以(yi)下(xia)簡稱快充(chong)(chong)）"和"慢(man)(man)速充(chong)(chong)電(dian)(dian)器（以(yi)下(xia)簡稱慢(man)(man)充(chong)(chong)）"兩種。鎳氫電(dian)(dian)池的(de)充(chong)(chong)電(dian)(dian)時(shi)間(jian)(jian)基本上(shang)可(ke)按下(xia)列公式計算：充(chong)(chong)電(dian)(dian)時(shi)間(jian)(jian)（小時(shi)）≈效率(lv)系數×容量（mAh）÷充(chong)(chong)電(dian)(dian)電(dian)(dian)流(liu)(mA) 注：效率(lv)系數為1.2～1.5之(zhi)間(jian)(jian)的(de)一個(ge)不定數，因不同充(chong)(chong)電(dian)(dian)器而異(yi)。

　　慢(man)充(chong)(chong)(chong)一般采(cai)用(yong)恒流(liu)方式充(chong)(chong)(chong)電(dian)，且(qie)在電(dian)池(chi)(chi)充(chong)(chong)(chong)滿后自(zi)動轉為涓(juan)流(liu)充(chong)(chong)(chong)電(dian)狀(zhuang)態(tai)。慢(man)充(chong)(chong)(chong)的(de)(de)優點(dian)是(shi)電(dian)路設計(ji)簡單(dan)，易于實現，價格也(ye)較低;由(you)于采(cai)用(yong)小電(dian)流(liu)恒流(liu)充(chong)(chong)(chong)電(dian)，有效(xiao)地降低了電(dian)池(chi)(chi)在充(chong)(chong)(chong)電(dian)過程(cheng)中的(de)(de)發(fa)熱量，對延長電(dian)池(chi)(chi)的(de)(de)使用(yong)壽命(ming)很有好(hao)處(chu)。缺(que)點(dian)就是(shi)充(chong)(chong)(chong)電(dian)時間太長,特別是(shi)電(dian)池(chi)(chi)數(shu)量較多的(de)(de)情況下(xia)有點(dian)力不從心。

　　快(kuai)充(chong)(chong)一般都采用(yong)(yong)脈沖大電(dian)(dian)流充(chong)(chong)電(dian)(dian)，但由(you)于電(dian)(dian)池(chi)(chi)在大電(dian)(dian)流充(chong)(chong)電(dian)(dian)過(guo)(guo)程(cheng)中會(hui)產生極化反應，導致電(dian)(dian)池(chi)(chi)溫(wen)度(du)迅速升高(gao)，充(chong)(chong)滿(man)后若(ruo)再(zai)繼續加(jia)電(dian)(dian)就(jiu)有可能發(fa)生爆炸(zha)和燃(ran)燒(shao)，所以快(kuai)充(chong)(chong)還采用(yong)(yong)專(zhuan)用(yong)(yong)芯片來控(kong)制充(chong)(chong)電(dian)(dian)過(guo)(guo)程(cheng)，實(shi)時監控(kong)電(dian)(dian)池(chi)(chi)電(dian)(dian)量，一旦充(chong)(chong)滿(man)就(jiu)自動停止充(chong)(chong)電(dian)(dian)，使整個充(chong)(chong)電(dian)(dian)過(guo)(guo)程(cheng)變得安(an)全、高(gao)效。快(kuai)充(chong)(chong)適合電(dian)(dian)池(chi)(chi)數量較多或心急(ji)的(de)玩家。缺點便(bian)是無法(fa)避免的(de)大發(fa)熱量，對電(dian)(dian)池(chi)(chi)壽命有一定的(de)影(ying)響(xiang).價格也(ye)比(bi)慢充(chong)(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)一個重要標(biao)準。兩者(zhe)比較起(qi)來(lai)，快(kuai)充的(de)(de)(de)(de)(de)(de)缺(que)點是(shi)對電(dian)(dian)池的(de)(de)(de)(de)(de)(de)壽命有所(suo)(suo)影(ying)響以及(ji)價格較高。不(bu)過(guo)在(zai)這個效率至上的(de)(de)(de)(de)(de)(de)時(shi)代，快(kuai)充的(de)(de)(de)(de)(de)(de)流行趨勢越(yue)來(lai)越(yue)明(ming)顯，因為(wei)使用快(kuai)充所(suo)(suo)節(jie)省的(de)(de)(de)(de)(de)(de)時(shi)間(jian)遠比電(dian)(dian)池所(suo)(suo)減少的(de)(de)(de)(de)(de)(de)壽命來(lai)得重要。況(kuang)且現在(zai)充電(dian)(dian)電(dian)(dian)池的(de)(de)(de)(de)(de)(de)價格也越(yue)來(lai)越(yue)低，所(suo)(suo)以在(zai)資(zi)金允許(xu)的(de)(de)(de)(de)(de)(de)情(qing)況(kuang)下，最(zui)好選擇快(kuai)充。 （質量較差的(de)(de)(de)(de)(de)(de)充電(dian)(dian)器(qi)內部構(gou)造極為(wei)簡單，電(dian)(dian)路板的(de)(de)(de)(de)(de)(de)工藝更是(shi)糟糕，因此如果是(shi)買非名牌充電(dian)(dian)器(qi)的(de)(de)(de)(de)(de)(de)話(hua)，開蓋看(kan)看(kan)還是(shi)有必要的(de)(de)(de)(de)(de)(de)）

　　外(wai)觀(guan)及內(nei)在(zai)(zai)品(pin)質(zhi)：優秀(xiu)的(de)(de)(de)(de)做(zuo)工在(zai)(zai)很(hen)大程度(du)上(shang)也是(shi)(shi)廠商實(shi)力的(de)(de)(de)(de)體現(xian)，而用(yong)(yong)料(liao)的(de)(de)(de)(de)質(zhi)量則是(shi)(shi)安全(quan)使用(yong)(yong)的(de)(de)(de)(de)保(bao)障。我們在(zai)(zai)購(gou)買時，可(ke)(ke)注意(yi)一下充電(dian)(dian)(dian)器(qi)(qi)(qi)外(wai)觀(guan)的(de)(de)(de)(de)光(guang)澤度(du)、邊角(jiao)和小(xiao)地(di)方的(de)(de)(de)(de)精細程度(du)；掂掂分量做(zuo)一下比較，一般來說同類型(xing)產品(pin)偷工減料(liao)者重(zhong)量相(xiang)對較輕。須要注意(yi)的(de)(de)(de)(de)是(shi)(shi)，快充由于使用(yong)(yong)了(le)控制(zhi)芯片以(yi)(yi)及開關電(dian)(dian)(dian)源(yuan)|穩(wen)壓器(qi)(qi)(qi)，重(zhong)量有可(ke)(ke)能會比慢充輕，所以(yi)(yi)掂重(zhong)量這(zhe)種差別(bie)方法(fa)最適合于同一類型(xing)的(de)(de)(de)(de)充電(dian)(dian)(dian)器(qi)(qi)(qi)。在(zai)(zai)條件(jian)允(yun)許的(de)(de)(de)(de)情況下可(ke)(ke)以(yi)(yi)要求(qiu)商家(jia)將充電(dian)(dian)(dian)器(qi)(qi)(qi)打開觀(guan)看內(nei)部結(jie)構，看看內(nei)部電(dian)(dian)(dian)路板(ban)電(dian)(dian)(dian)子元件(jian)的(de)(de)(de)(de)排列、焊接工藝等方面，以(yi)(yi)確(que)保(bao)貨(huo)真價(jia)實(shi)。另外(wai),最好將自己使用(yong)(yong)的(de)(de)(de)(de)充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)帶上(shang)，在(zai)(zai)商家(jia)處(chu)充電(dian)(dian)(dian)30分鐘左右,觀(guan)察一下電(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)發熱(re)(re)量--質(zhi)量好的(de)(de)(de)(de)充電(dian)(dian)(dian)器(qi)(qi)(qi)能夠有效(xiao)地(di)控制(zhi)發熱(re)(re)量,而劣質(zhi)充電(dian)(dian)(dian)器(qi)(qi)(qi)則有可(ke)(ke)能將電(dian)(dian)(dian)池(chi)充得滾燙(tang)--這(zhe)種現(xian)象特別(bie)容易出現(xian)在(zai)(zai)劣質(zhi)快充上(shang)。這(zhe)樣的(de)(de)(de)(de)產品(pin)一定不能購(gou)買。

　　易用性：為(wei)了日(ri)后使用更加方便，在選擇(ze)充電器時最好多考慮一下產品的易用性。

　　有(you)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只能(neng)(neng)為(wei)AA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而(er)有(you)些充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)不但能(neng)(neng)充(chong)(chong)(chong)AA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，還(huan)可以(yi)為(wei)AAA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，如果有(you)多(duo)(duo)種型號(hao)的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，可以(yi)選擇這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。 常(chang)見的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)一(yi)般可以(yi)同時為(wei)4節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，手(shou)中的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)比較(jiao)多(duo)(duo)，同時又(you)不愿意為(wei)大量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)而(er)長時間等(deng)待的(de)(de)(de)(de)用戶，可以(yi)選擇有(you)6個或8個甚至更多(duo)(duo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)插槽的(de)(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，當然，這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)(de)(de)體積會(hui)大一(yi)些，不便(bian)攜帶(dai)，價格(ge)也自然會(hui)高一(yi)些。 很多(duo)(duo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路設計的(de)(de)(de)(de)關系,只能(neng)(neng)為(wei)偶數節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)如2節、4節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)成對地充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這對于(yu)某(mou)些使(shi)用單個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)用戶來說很不方便(bian)，于(yu)是(shi)市場有(you)一(yi)些充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路設計時考(kao)慮到了這一(yi)問題，它們可以(yi)為(wei)1節、3節等(deng)奇(qi)數節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。在購買(mai)時建議選擇這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，以(yi)便(bian)日后(hou)的(de)(de)(de)(de)使(shi)用。由(you)于(yu)鎳(nie)氫和鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)結構相近，所以(yi)有(you)的(de)(de)(de)(de)鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)在設計時還(huan)考(kao)慮到了對鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)兼容，如果想讓手(shou)中的(de)(de)(de)(de)老電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)再次煥發青春，這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)倒是(shi)一(yi)個不錯(cuo)的(de)(de)(de)(de)選擇。

　　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)(cha)(cha)頭(tou)與機身做在(zai)了一起(qi)，不(bu)(bu)過在(zai)使用時(shi)往(wang)往(wang)會在(zai)多用插(cha)(cha)(cha)線(xian)板(ban)上占(zhan)去(qu)兩個(ge)甚至更多插(cha)(cha)(cha)座(zuo)的(de)位(wei)置，對于(yu)插(cha)(cha)(cha)座(zuo)比較集中(zhong)的(de)朋友來說，充電(dian)時(shi)就不(bu)(bu)得不(bu)(bu)把其(qi)他的(de)插(cha)(cha)(cha)頭(tou)拔掉，很不(bu)(bu)方(fang)便(bian)。如果不(bu)(bu)想為充電(dian)器另行購買一個(ge)插(cha)(cha)(cha)線(xian)板(ban)的(de)話(hua)，就應該選擇非一體式的(de)充電(dian)器了。
