我們這里應廣大讀者的要求，回答一些常見的關于充電器的問題。我們僅討論最常用的鎳氫電池和鎳鎘電池充電器，不包括最新的鉛酸電池和鋰離子電池充電器。 

一、疾速(su)充(chong)(chong)電器和快速(su)充(chong)(chong)電器的區別是什么？ 

　　這(zhe)兩者的(de)(de)比(bi)較實際上(shang)是(shi)沒有任何意義(yi)的(de)(de)。在電(dian)(dian)(dian)池(chi)(chi)行業內，對這(zhe)兩種充電(dian)(dian)(dian)器(qi)(qi)沒有明確的(de)(de)界定。因此制造商們也經常把它們弄混。有一個問題就是(shi)，充滿(man)(man)一節電(dian)(dian)(dian)池(chi)(chi)的(de)(de)時(shi)(shi)(shi)(shi)間依(yi)賴(lai)于(yu)被充電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)容量。一個需(xu)(xu)花1小時(shi)(shi)(shi)(shi)充滿(man)(man)1節標(biao)準容量的(de)(de)AAA鎳鎘電(dian)(dian)(dian)池(chi)(chi)（180 mAh）充電(dian)(dian)(dian)器(qi)(qi)，可能需(xu)(xu)要8小時(shi)(shi)(shi)(shi)才能充滿(man)(man)1節高容量的(de)(de)鎳氫電(dian)(dian)(dian)池(chi)(chi)（1500 mAh）。最好的(de)(de)辦法是(shi)忽(hu)略這(zhe)些差(cha)異(yi)，粗(cu)略地計算一下充電(dian)(dian)(dian)器(qi)(qi)充滿(man)(man)電(dian)(dian)(dian)池(chi)(chi)所需(xu)(xu)的(de)(de)時(shi)(shi)(shi)(shi)間。 

二、每次要花多(duo)長時間才能把電池(chi)充滿？  

我們(men)可(ke)以(yi)很容(rong)易計(ji)算(suan)出充電(dian)(dian)器(qi)(qi)(qi)所(suo)花的(de)(de)(de)(de)時(shi)間。用電(dian)(dian)池(chi)的(de)(de)(de)(de)容(rong)量，簡單地除以(yi)充電(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)充電(dian)(dian)效率，然(ran)后增加(jia)20%作為(wei)(wei)無效工作時(shi)間。舉個例子(zi)(zi)，使用一個充電(dian)(dian)率為(wei)(wei)500mA的(de)(de)(de)(de)充電(dian)(dian)器(qi)(qi)(qi)大約需(xu)4小時(shi)才能充滿(man)一節(jie)有(you)1600mAh的(de)(de)(de)(de)電(dian)(dian)池(chi)，計(ji)算(suan)式子(zi)(zi)為(wei)(wei)1600 mAh/500 mA x120%。這個例子(zi)(zi)也(ye)許(xu)偶(ou)然(ran)適用于疾速(su)充電(dian)(dian)器(qi)(qi)(qi)對(dui)標準5號鎳氫電(dian)(dian)池(chi)充電(dian)(dian)的(de)(de)(de)(de)情況。記住，如果一節(jie)電(dian)(dian)池(chi)只(zhi)是部分放(fang)電(dian)(dian)，顯(xian)然(ran)，我們(men)只(zhi)需(xu)要花更少的(de)(de)(de)(de)時(shi)間就能夠(gou)把它充滿(man)電(dian)(dian)。 

　　如果(guo)你覺得(de)這(zhe)個太(tai)復雜(za)了(le)(le)，可以使(shi)用我(wo)們(men)特別的(de)電(dian)池充電(dian)時(shi)間計(ji)算器(qi)。你只需要(yao)輸入上面連續的(de)兩個值就行了(le)(le)。然后按Calculate（計(ji)算），結果(guo)就會立即在hours（小時(shi)）前的(de)窗(chuang)口中出現。 

三、使用充電器會對電(dian)池(chi)有損(sun)害嗎（會減少電(dian)池(chi)壽命或(huo)降(jiang)低(di)電(dian)池(chi)使用(yong)效果）？  

　　是的。最常見的充電失敗就是充電時間過長，俗稱過度充電。有一種充電器特別容易導致過度充電，通常充5小時以上（有的是8小時）電池就會報廢，這種充電器就是所謂的“疾速充電器”。這種充電器的(de)(de)(de)(de)(de)問題就(jiu)是，沒有一個充(chong)電(dian)(dian)(dian)控制裝置(zhi)。大(da)部(bu)分疾速(su)充(chong)電(dian)(dian)(dian)器通常(chang)設計非常(chang)簡單，它們(men)(men)一般以(yi)最大(da)速(su)率(lv)(lv)充(chong)電(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)時間也比(bi)較(jiao)固定，通常(chang)是5或8小(xiao)時就(jiu)充(chong)滿了。然后，你就(jiu)應該把它們(men)(men)關掉，或者轉向特慢的(de)(de)(de)(de)(de)涓流充(chong)電(dian)(dian)(dian)速(su)率(lv)(lv)。如果你正確(que)的(de)(de)(de)(de)(de)使(shi)用(yong)(yong)充(chong)電(dian)(dian)(dian)器，它通常(chang)對電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)損害不大(da)。如果沒有正確(que)的(de)(de)(de)(de)(de)使(shi)用(yong)(yong)，充(chong)電(dian)(dian)(dian)器通常(chang)會以(yi)兩(liang)種方式縮短電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)壽命。 

　　首(shou)先，設想把(ba)(ba)完全充(chong)(chong)(chong)電(dian)(dian)(dian)后(hou)和部分充(chong)(chong)(chong)電(dian)(dian)(dian)后(hou)的(de)電(dian)(dian)(dian)池(chi)放(fang)進充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)內(nei)(nei)。但是充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)并不知道電(dian)(dian)(dian)池(chi)內(nei)(nei)有電(dian)(dian)(dian)。因(yin)此它還(huan)是對電(dian)(dian)(dian)池(chi)進行完全充(chong)(chong)(chong)電(dian)(dian)(dian)。我(wo)們(men)很(hen)少見到把(ba)(ba)部分充(chong)(chong)(chong)電(dian)(dian)(dian)后(hou)的(de)電(dian)(dian)(dian)池(chi)放(fang)進充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)內(nei)(nei)的(de)，因(yin)為這很(hen)容易混(hun)淆電(dian)(dian)(dian)池(chi)，不經意間就把(ba)(ba)充(chong)(chong)(chong)滿電(dian)(dian)(dian)后(hou)的(de)電(dian)(dian)(dian)池(chi)放(fang)進充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)內(nei)(nei)了。如果你多次對充(chong)(chong)(chong)滿電(dian)(dian)(dian)后(hou)的(de)電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)，它的(de)**能(neng)就會(hui)慢(man)慢(man)降低。 

　　另外(wai)，通(tong)常(chang)情況下，充(chong)(chong)電(dian)周期不(bu)穩定，很容易被打(da)斷。我們通(tong)常(chang)把充(chong)(chong)電(dian)器(qi)拔開(kai)，看看電(dian)池的(de)熱度(du)如何。然后，再(zai)把充(chong)(chong)電(dian)器(qi)插(cha)回去。不(bu)幸的(de)是，這(zhe)通(tong)常(chang)會(hui)導致重新開(kai)始(shi)完整(zheng)的(de)充(chong)(chong)電(dian)周期，前(qian)面的(de)充(chong)(chong)電(dian)周期已(yi)經完成了(le)。這(zhe)也常(chang)會(hui)降低電(dian)池壽命。 

為(wei)了避免這些問題，我(wo)們可以使(shi)用(yong)一個智(zhi)能充(chong)電(dian)(dian)器，它有微處理(li)器控制。智(zhi)能充(chong)電(dian)(dian)器通常會決定什么時候電(dian)(dian)池充(chong)滿了電(dian)(dian)，然后根據設計的不同，完(wan)全關掉(diao)充(chong)電(dian)(dian)器或(huo)轉(zhuan)向(xiang)涓流充(chong)電(dian)(dian)。 

四、什么是涓流充(chong)電(dian)（使蓄電(dian)池緩慢而連續充(chong)電(dian)的裝備(bei)）？  

　　理論(lun)上說，涓流充(chong)電(dian)是(shi)(shi)指一種充(chong)電(dian)速率(lv)高至使電(dian)池完全充(chong)滿電(dian)、低至可避免(mian)過度充(chong)電(dian)的充(chong)電(dian)方(fang)式(shi)。維持充(chong)電(dian)也是(shi)(shi)描述涓流充(chong)電(dian)的一種方(fang)式(shi)。 

五(wu)、涓流充(chong)電(dian)(dian)對電(dian)(dian)池(chi)有損害(hai)嗎？  

　　許(xu)多電池制造商建議不要長期使用涓流充(chong)電。 

　　如果使用涓流充(chong)(chong)(chong)(chong)電(dian)(dian)，那么充(chong)(chong)(chong)(chong)電(dian)(dian)速(su)率(lv)就會非常低(di)，并且(qie)有(you)(you)(you)時(shi)斷斷續續。當給電(dian)(dian)池充(chong)(chong)(chong)(chong)電(dian)(dian)時(shi)，最好的智能充(chong)(chong)(chong)(chong)電(dian)(dian)器只(zhi)能進行臨時(shi)的充(chong)(chong)(chong)(chong)電(dian)(dian)速(su)率(lv)變化。它們沒有(you)(you)(you)連續的低(di)速(su)率(lv)充(chong)(chong)(chong)(chong)電(dian)(dian)功(gong)能。一些電(dian)(dian)池經(jing)銷(xiao)商說，如果進行長期的涓流充(chong)(chong)(chong)(chong)電(dian)(dian)，只(zhi)有(you)(you)(you)十分之一的電(dian)(dian)池能量不會受到(dao)傷害。然而，我(wo)們還沒有(you)(you)(you)見到(dao)任何廠商進行這樣的測試。 

　　最好還是(shi)把電(dian)池(chi)完(wan)全充滿電(dian)，然后儲存好。不要進行額外的(de)涓(juan)流充電(dian)。免得出現意外的(de)損害。 

六、疾(ji)速充電會減少電池的(de)壽命嗎？  

　　不(bu)是很(hen)嚴(yan)重。只要使(shi)用(yong)了一個(ge)適當(dang)的(de)智能(neng)充(chong)(chong)電(dian)器，你就能(neng)在(zai)約一個(ge)小時內把幾乎各(ge)種鎳(nie)(nie)氫(qing)電(dian)池(chi)(chi)完全(quan)充(chong)(chong)好電(dian)，并且(qie)沒(mei)有任(ren)何損壞(huai)，電(dian)池(chi)(chi)壽(shou)命也不(bu)會有大(da)幅降低，可能(neng)減少不(bu)到10%。顯然，這總(zong)是比使(shi)用(yong)慢速充(chong)(chong)電(dian)器好多了。然而，只能(neng)使(shi)用(yong)特別設計(ji)(ji)的(de)鎳(nie)(nie)氫(qing)電(dian)池(chi)(chi)充(chong)(chong)電(dian)器給大(da)多數鎳(nie)(nie)氫(qing)電(dian)池(chi)(chi)快速充(chong)(chong)電(dian)。另外(wai)，專為鎳(nie)(nie)鎘電(dian)池(chi)(chi)充(chong)(chong)電(dian)設計(ji)(ji)的(de)疾速充(chong)(chong)電(dian)器很(hen)可能(neng)會給鎳(nie)(nie)氫(qing)電(dian)池(chi)(chi)過度充(chong)(chong)電(dian)。 

七、鎳(nie)氫(qing)電池(chi)充電器和鎳(nie)鎘電池(chi)充電器的(de)區別是什么？  

　　最大的(de)(de)差別在于充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率（充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)速度(du)），以(yi)及充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控制(zhi)（怎么(me)什么(me)時候(hou)決定停止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)）。 許多廉價的(de)(de)鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器經過簡單的(de)(de)改造，就(jiu)(jiu)成了(le)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。通(tong)(tong)常(chang)，一(yi)(yi)個(ge)5小時的(de)(de)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)有一(yi)(yi)個(ge)開關(guan)，允(yun)許充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間從(cong)5個(ge)小時增加到8個(ge)小時。 這樣，一(yi)(yi)個(ge)5小時鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器就(jiu)(jiu)變成了(le)一(yi)(yi)個(ge)8小時鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。我們在這里(li)并(bing)不是說(shuo)推薦(jian)使(shi)用這種充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器。然而，一(yi)(yi)個(ge)定時的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器相比(bi)一(yi)(yi)個(ge)智(zhi)能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，生產成本要少一(yi)(yi)些。如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)之前進行頻繁的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)（也就(jiu)(jiu)是說(shuo)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)只使(shi)用了(le)很短的(de)(de)時間，然后又立即被完全充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)），定時充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器通(tong)(tong)常(chang)導致過度(du)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，或者電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)損害。 

　　鎳(nie)氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)智能(neng)(neng)充(chong)電(dian)(dian)(dian)(dian)器(qi)實際上是專門檢測鎳(nie)氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)什(shen)么時候被充(chong)滿了。然(ran)后，關上開關或轉(zhuan)向涓流(liu)充(chong)電(dian)(dian)(dian)(dian)模式。顯然(ran)，這要(yao)經過更復雜的電(dian)(dian)(dian)(dian)路。所以，這類充(chong)電(dian)(dian)(dian)(dian)器(qi)要(yao)花(hua)費更多的時間與金錢。但是，它可能(neng)(neng)會延(yan)長電(dian)(dian)(dian)(dian)池(chi)的壽命。有些(xie)智能(neng)(neng)充(chong)電(dian)(dian)(dian)(dian)器(qi)僅僅比定時充(chong)電(dian)(dian)(dian)(dian)器(qi)稍(shao)微花(hua)多一(yi)點成本。我們強烈建議，當你(ni)想購買智能(neng)(neng)充(chong)電(dian)(dian)(dian)(dian)器(qi)時，調查一(yi)下它與鎳(nie)氫(qing)(qing)或鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)池(chi)的兼容(rong)**。 

八(ba)、能夠使用舊的鎳鎘電(dian)池(chi)充電(dian)器對鎳氫電(dian)池(chi)充電(dian)嗎？  

　　這(zhe)個(ge)問題(ti)的(de)**取決于(yu)鎳(nie)鎘充(chong)(chong)電(dian)器的(de)類型。由于(yu)有這(zhe)種依賴**，舊(jiu)的(de)鎳(nie)鎘電(dian)池充(chong)(chong)電(dian)器可(ke)(ke)能(neng)不(bu)會給(gei)鎳(nie)氫(qing)電(dian)池充(chong)(chong)滿電(dian)（是很有可(ke)(ke)能(neng)），幾乎不(bu)可(ke)(ke)能(neng)發生過度充(chong)(chong)電(dian)的(de)情(qing)況， 或適(shi)當地(di)給(gei)鎳(nie)氫(qing)電(dian)池充(chong)(chong)電(dian)（但是它不(bu)可(ke)(ke)能(neng)自動處理(li)，結果還是要花很長時(shi)間）。讓我們來看一下這(zhe)三種情(qing)況。 

　　許多“古老(lao)”的鎳鎘(ge)電(dian)池(chi)充電(dian)器(qi)是(shi)簡單(dan)的定(ding)(ding)時(shi)充電(dian)器(qi)，充電(dian)時(shi)間都是(shi)固(gu)定(ding)(ding)好(hao)了(le)(le)的。時(shi)間一(yi)到，就(jiu)自動(dong)關上了(le)(le)。不(bu)幸的是(shi)，因為(wei)鎳鎘(ge)電(dian)池(chi)比(bi)鎳氫(qing)電(dian)池(chi)的容量小，當使用鎳鎘(ge)電(dian)池(chi)的時(shi)間標準給鎳氫(qing)電(dian)池(chi)充電(dian)時(shi)，充電(dian)可能會提(ti)前中止。這雖然不(bu)會傷(shang)害(hai)電(dian)池(chi)，但(dan)是(shi)鎳氫(qing)電(dian)池(chi)肯定(ding)(ding)不(bu)會被完全充滿電(dian)，因為(wei)定(ding)(ding)時(shi)器(qi)早(zao)就(jiu)固(gu)定(ding)(ding)好(hao)了(le)(le)。充電(dian)器(qi)停止充電(dian)，顯然是(shi)太早(zao)了(le)(le)。充電(dian)周期也就(jiu)會縮短。 

　　另外(wai)，在更(geng)舊的(de)鎳(nie)鎘(ge)電(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)之中，有一(yi)種(zhong)非(fei)常(chang)普通的(de)充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)，就(jiu)是所謂的(de)“通宵(xiao)”充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)。只要充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)接(jie)通了電(dian)(dian)源，它(ta)的(de)充(chong)(chong)(chong)電(dian)(dian)速率(lv)就(jiu)非(fei)常(chang)低。 這(zhe)(zhe)類充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)能(neng)(neng)為鎳(nie)氫(qing)電(dian)(dian)池(chi)充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)，但是它(ta)可(ke)能(neng)(neng)花上很長的(de)時間(jian)。一(yi)個舊的(de)鎳(nie)鎘(ge)電(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)很可(ke)能(neng)(neng)要花上48個小(xiao)時才能(neng)(neng)給新(xin)款高(gao)電(dian)(dian)容的(de)鎳(nie)氫(qing)電(dian)(dian)池(chi)充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)！這(zhe)(zhe)類充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)幾(ji)乎不可(ke)能(neng)(neng)損(sun)壞鎳(nie)氫(qing)電(dian)(dian)池(chi)，除非(fei)把鎳(nie)氫(qing)電(dian)(dian)池(chi)放(fang)在充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)里長達一(yi)個星期，但是這(zhe)(zhe)樣就(jiu)不方便使用了。如果你有這(zhe)(zhe)種(zhong)類型的(de)充(chong)(chong)(chong)電(dian)(dian)器(qi)(qi)，應(ying)該(gai)根據我們(men)上面(mian)的(de)公式簡(jian)單(dan)的(de)把充(chong)(chong)(chong)電(dian)(dian)時間(jian)算出來 

　　但是(shi)(shi)，最終(zhong)我們可能(neng)選擇(ze)一(yi)(yi)(yi)款更(geng)舊的(de)鎳(nie)(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)：疾速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。它給鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，不需要(yao)(yao)多余的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。因(yin)為一(yi)(yi)(yi)旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)滿后，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)周期(qi)就停止了，被(bei)記錄下來。如(ru)果鎳(nie)(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)將(jiang)在(zai)2個小時以內(nei)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，那(nei)么(me)(me)它就可以說是(shi)(shi)疾速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。在(zai)這(zhe)個情況中(zhong)，唯(wei)一(yi)(yi)(yi)的(de)風險就是(shi)(shi)：更(geng)舊的(de)疾速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)可能(neng)會(hui)(hui)(hui)給鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過(guo)度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。如(ru)果在(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)周期(qi)中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)變得(de)(de)很熱，那(nei)么(me)(me)這(zhe)就是(shi)(shi)過(guo)度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)征兆（一(yi)(yi)(yi)般來說，當鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)被(bei)充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后，就會(hui)(hui)(hui)變得(de)(de)溫暖一(yi)(yi)(yi)些，特別是(shi)(shi)使用(yong)疾速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時）。如(ru)果鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)變得(de)(de)太熱，我們無法及時處(chu)理，當持續20或30分(fen)鐘后，鎳(nie)(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)就很可能(neng)對(dui)鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)過(guo)度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)了，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)壽命就會(hui)(hui)(hui)縮短。如(ru)果充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)專(zhuan)為需迅速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)收音機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，你很可能(neng)遇見到(dao)這(zhe)類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。我們建(jian)議不要(yao)(yao)使用(yong)鎳(nie)(nie)(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)疾速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)給鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。
