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(yi)、疾(ji)速(su)充電(dian)(dian)器和快速(su)充電(dian)(dian)器的區別是什么？ 

　　這兩者(zhe)的(de)比較實(shi)際上是(shi)沒(mei)有任何意義的(de)。在(zai)電(dian)(dian)池(chi)行業內(nei)，對這兩種充(chong)電(dian)(dian)器(qi)沒(mei)有明確(que)的(de)界定。因此制造商們也經(jing)常把它們弄混。有一個(ge)問題就(jiu)是(shi)，充(chong)滿一節電(dian)(dian)池(chi)的(de)時(shi)間(jian)依賴于被充(chong)電(dian)(dian)的(de)電(dian)(dian)池(chi)的(de)容量。一個(ge)需花1小時(shi)充(chong)滿1節標準容量的(de)AAA鎳鎘電(dian)(dian)池(chi)（180 mAh）充(chong)電(dian)(dian)器(qi)，可能(neng)需要8小時(shi)才(cai)能(neng)充(chong)滿1節高容量的(de)鎳氫電(dian)(dian)池(chi)（1500 mAh）。最好的(de)辦(ban)法是(shi)忽略這些差異，粗略地計算一下充(chong)電(dian)(dian)器(qi)充(chong)滿電(dian)(dian)池(chi)所(suo)需的(de)時(shi)間(jian)。 

二、每次要花多(duo)長時間才能把電(dian)池(chi)充滿？  

我們可以(yi)很容(rong)易計(ji)算出(chu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)所花(hua)的(de)時間(jian)。用(yong)電(dian)(dian)(dian)(dian)(dian)池的(de)容(rong)量，簡(jian)單地除以(yi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)效(xiao)率，然后(hou)增加20%作(zuo)為(wei)無效(xiao)工作(zuo)時間(jian)。舉個(ge)(ge)例(li)子，使用(yong)一(yi)個(ge)(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)率為(wei)500mA的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)大約需(xu)4小時才能充(chong)(chong)滿(man)一(yi)節有(you)1600mAh的(de)電(dian)(dian)(dian)(dian)(dian)池，計(ji)算式(shi)子為(wei)1600 mAh/500 mA x120%。這個(ge)(ge)例(li)子也許(xu)偶然適用(yong)于疾速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)對標(biao)準5號鎳氫電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)情況(kuang)。記住，如果一(yi)節電(dian)(dian)(dian)(dian)(dian)池只是(shi)部分放電(dian)(dian)(dian)(dian)(dian)，顯(xian)然，我們只需(xu)要花(hua)更少的(de)時間(jian)就能夠把它充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)。 

　　如果(guo)你覺(jue)得這個(ge)太復雜了(le)，可(ke)以(yi)使用我們特別的(de)電池(chi)充電時間計算(suan)器。你只需(xu)要輸入上面(mian)連續的(de)兩個(ge)值就行了(le)。然后按Calculate（計算(suan)），結果(guo)就會立即在hours（小時）前的(de)窗口中出(chu)現。 

三、使用充電器會對(dui)電(dian)池有損(sun)害嗎（會減少(shao)電(dian)池壽命(ming)或降低電(dian)池使(shi)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)問題就(jiu)(jiu)是，沒有一個充(chong)電(dian)(dian)控制裝置。大部分疾(ji)速充(chong)電(dian)(dian)器通(tong)常(chang)設(she)計非常(chang)簡單，它們一般以最大速率充(chong)電(dian)(dian)，充(chong)電(dian)(dian)時間也比較固(gu)定，通(tong)常(chang)是5或8小時就(jiu)(jiu)充(chong)滿了。然后，你就(jiu)(jiu)應該把它們關(guan)掉，或者轉(zhuan)向特慢(man)的(de)涓流充(chong)電(dian)(dian)速率。如果你正確(que)的(de)使用充(chong)電(dian)(dian)器，它通(tong)常(chang)對電(dian)(dian)池的(de)損害(hai)不大。如果沒有正確(que)的(de)使用，充(chong)電(dian)(dian)器通(tong)常(chang)會(hui)以兩種方式縮短電(dian)(dian)池的(de)壽命。 

　　首先，設想把完全充(chong)電后和部分(fen)充(chong)電后的(de)電池(chi)放進(jin)(jin)(jin)充(chong)電器內。但是充(chong)電器并不(bu)知道電池(chi)內有電。因此(ci)它還(huan)是對電池(chi)進(jin)(jin)(jin)行完全充(chong)電。我們很少見(jian)到把部分(fen)充(chong)電后的(de)電池(chi)放進(jin)(jin)(jin)充(chong)電器內的(de)，因為(wei)這很容易(yi)混淆電池(chi)，不(bu)經(jing)意間就把充(chong)滿電后的(de)電池(chi)放進(jin)(jin)(jin)充(chong)電器內了。如果(guo)你(ni)多(duo)次對充(chong)滿電后的(de)電池(chi)充(chong)電，它的(de)**能就會慢慢降低。 

　　另外，通常情況(kuang)下，充電(dian)(dian)周(zhou)(zhou)期(qi)(qi)不(bu)穩(wen)定，很容易被打(da)斷。我們通常把充電(dian)(dian)器(qi)拔開，看看電(dian)(dian)池的熱度如(ru)何(he)。然后，再把充電(dian)(dian)器(qi)插回去。不(bu)幸(xing)的是，這通常會(hui)導致重新開始完(wan)整的充電(dian)(dian)周(zhou)(zhou)期(qi)(qi)，前面的充電(dian)(dian)周(zhou)(zhou)期(qi)(qi)已經完(wan)成了(le)。這也常會(hui)降低電(dian)(dian)池壽命(ming)。 

為(wei)了避(bi)免這(zhe)些問(wen)題，我們可以使(shi)用一個智能充電(dian)器(qi)，它有微處理器(qi)控制(zhi)。智能充電(dian)器(qi)通常會決定什么(me)時(shi)候電(dian)池充滿了電(dian)，然(ran)后根(gen)據(ju)設計的不同，完全關掉(diao)充電(dian)器(qi)或轉向涓流充電(dian)。 

四、什么是涓(juan)流充電(dian)（使蓄電(dian)池(chi)緩慢(man)而連續充電(dian)的裝備）？  

　　理(li)論(lun)上說，涓流充(chong)(chong)電(dian)(dian)是指一(yi)種充(chong)(chong)電(dian)(dian)速率高至使電(dian)(dian)池完(wan)全充(chong)(chong)滿電(dian)(dian)、低至可避免過度充(chong)(chong)電(dian)(dian)的充(chong)(chong)電(dian)(dian)方(fang)式(shi)。維持充(chong)(chong)電(dian)(dian)也(ye)是描述涓流充(chong)(chong)電(dian)(dian)的一(yi)種方(fang)式(shi)。 

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

　　許多電(dian)池制造商建議不要長期(qi)使(shi)用涓流充電(dian)。 

　　如果(guo)使用(yong)涓流(liu)充(chong)(chong)電(dian)(dian)，那么充(chong)(chong)電(dian)(dian)速率就(jiu)會非常低，并(bing)且有時斷斷續(xu)續(xu)。當給電(dian)(dian)池充(chong)(chong)電(dian)(dian)時，最好的(de)(de)(de)智(zhi)能(neng)(neng)充(chong)(chong)電(dian)(dian)器只(zhi)能(neng)(neng)進行(xing)臨(lin)時的(de)(de)(de)充(chong)(chong)電(dian)(dian)速率變化。它(ta)們(men)沒有連(lian)續(xu)的(de)(de)(de)低速率充(chong)(chong)電(dian)(dian)功(gong)能(neng)(neng)。一些電(dian)(dian)池經銷(xiao)商說，如果(guo)進行(xing)長期的(de)(de)(de)涓流(liu)充(chong)(chong)電(dian)(dian)，只(zhi)有十(shi)分(fen)之一的(de)(de)(de)電(dian)(dian)池能(neng)(neng)量不會受(shou)到傷害(hai)。然而，我(wo)們(men)還(huan)沒有見到任何廠商進行(xing)這樣的(de)(de)(de)測試。 

　　最好還是把電池完全充滿電，然后儲存好。不要(yao)進行額外(wai)的涓流充電。免得出現意(yi)外(wai)的損害。 

六、疾速充(chong)電(dian)會減少電(dian)池的壽命嗎(ma)？  

　　不(bu)是很嚴重。只要使(shi)用(yong)了(le)一個適當的(de)智能充(chong)電(dian)(dian)器，你就能在約一個小時內把幾乎各種鎳氫電(dian)(dian)池(chi)完全(quan)充(chong)好電(dian)(dian)，并且沒有任何損(sun)壞，電(dian)(dian)池(chi)壽(shou)命也不(bu)會(hui)有大幅降低(di)，可(ke)能減少(shao)不(bu)到10%。顯然，這總是比使(shi)用(yong)慢速充(chong)電(dian)(dian)器好多了(le)。然而，只能使(shi)用(yong)特別設計的(de)鎳氫電(dian)(dian)池(chi)充(chong)電(dian)(dian)器給(gei)大多數鎳氫電(dian)(dian)池(chi)快速充(chong)電(dian)(dian)。另外，專為鎳鎘電(dian)(dian)池(chi)充(chong)電(dian)(dian)設計的(de)疾速充(chong)電(dian)(dian)器很可(ke)能會(hui)給(gei)鎳氫電(dian)(dian)池(chi)過度充(chong)電(dian)(dian)。 

七、鎳(nie)(nie)氫電(dian)池充電(dian)器(qi)和(he)鎳(nie)(nie)鎘電(dian)池充電(dian)器(qi)的區別是(shi)什么？  

　　最(zui)大的(de)差別在于充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率（充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)速度），以及充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制（怎么什么時(shi)(shi)(shi)(shi)候決定(ding)停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)）。 許多廉價的(de)鎳氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)經(jing)過(guo)簡(jian)單的(de)改(gai)造，就(jiu)成(cheng)了鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。通常(chang)，一(yi)個(ge)(ge)5小(xiao)時(shi)(shi)(shi)(shi)的(de)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)有一(yi)個(ge)(ge)開關，允許充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)(shi)(shi)間從5個(ge)(ge)小(xiao)時(shi)(shi)(shi)(shi)增加到8個(ge)(ge)小(xiao)時(shi)(shi)(shi)(shi)。 這(zhe)樣，一(yi)個(ge)(ge)5小(xiao)時(shi)(shi)(shi)(shi)鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)就(jiu)變成(cheng)了一(yi)個(ge)(ge)8小(xiao)時(shi)(shi)(shi)(shi)鎳氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。我們在這(zhe)里并不是(shi)說(shuo)推薦使用這(zhe)種充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。然而，一(yi)個(ge)(ge)定(ding)時(shi)(shi)(shi)(shi)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)相比(bi)一(yi)個(ge)(ge)智能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，生產成(cheng)本要少一(yi)些。如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)在放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)之前進(jin)行(xing)頻(pin)繁的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)（也就(jiu)是(shi)說(shuo)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)只使用了很短(duan)的(de)時(shi)(shi)(shi)(shi)間，然后又(you)立即被(bei)完全(quan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)），定(ding)時(shi)(shi)(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)通常(chang)導致過(guo)度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，或者電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)損害。 

　　鎳氫電(dian)(dian)池(chi)智(zhi)能充(chong)電(dian)(dian)器(qi)(qi)實(shi)際上(shang)是專門檢(jian)測鎳氫電(dian)(dian)池(chi)什么時(shi)(shi)候被充(chong)滿了。然后，關(guan)上(shang)開關(guan)或轉向涓流(liu)充(chong)電(dian)(dian)模式(shi)。顯然，這要(yao)經過(guo)更復雜的電(dian)(dian)路。所以，這類充(chong)電(dian)(dian)器(qi)(qi)要(yao)花費更多(duo)的時(shi)(shi)間與金錢。但是，它可能會延長電(dian)(dian)池(chi)的壽命。有些智(zhi)能充(chong)電(dian)(dian)器(qi)(qi)僅僅比定時(shi)(shi)充(chong)電(dian)(dian)器(qi)(qi)稍微(wei)花多(duo)一點成本。我(wo)們強烈建(jian)議，當你想購買智(zhi)能充(chong)電(dian)(dian)器(qi)(qi)時(shi)(shi)，調查一下(xia)它與鎳氫或鎳鎘電(dian)(dian)池(chi)的兼容(rong)**。 

八、能夠(gou)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)個問題的(de)(de)**取決于鎳(nie)鎘(ge)(ge)充(chong)電(dian)(dian)器(qi)的(de)(de)類(lei)型。由(you)于有這(zhe)種依賴**，舊的(de)(de)鎳(nie)鎘(ge)(ge)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)可(ke)(ke)能不會給鎳(nie)氫電(dian)(dian)池(chi)充(chong)滿(man)電(dian)(dian)（是很有可(ke)(ke)能），幾乎不可(ke)(ke)能發生過(guo)度充(chong)電(dian)(dian)的(de)(de)情況(kuang)， 或適當地給鎳(nie)氫電(dian)(dian)池(chi)充(chong)電(dian)(dian)（但是它不可(ke)(ke)能自動(dong)處(chu)理，結果還是要花(hua)很長時(shi)間）。讓我們來看一下這(zhe)三種情況(kuang)。 

　　許(xu)多“古老”的(de)鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器是(shi)簡單的(de)定(ding)時(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間都是(shi)固定(ding)好了(le)(le)的(de)。時(shi)間一到，就(jiu)自動關上了(le)(le)。不幸的(de)是(shi)，因(yin)為鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)比鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)容量(liang)小，當使用鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)時(shi)間標準給鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)可能會(hui)(hui)提前中止(zhi)。這雖然不會(hui)(hui)傷(shang)害電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，但是(shi)鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)肯定(ding)不會(hui)(hui)被(bei)完(wan)全(quan)充(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)(dian)，因(yin)為定(ding)時(shi)器早就(jiu)固定(ding)好了(le)(le)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器停(ting)止(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，顯然是(shi)太(tai)早了(le)(le)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周期也就(jiu)會(hui)(hui)縮短。 

　　另外(wai)，在更(geng)舊(jiu)的(de)(de)鎳鎘電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)之中(zhong)，有一(yi)種非(fei)常普通(tong)(tong)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，就(jiu)是所謂(wei)的(de)(de)“通(tong)(tong)宵”充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)。只要充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)接通(tong)(tong)了(le)電(dian)(dian)(dian)(dian)源，它(ta)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)速率就(jiu)非(fei)常低。 這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)能(neng)(neng)為鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)分充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，但(dan)是它(ta)可能(neng)(neng)花(hua)上很(hen)長的(de)(de)時(shi)間(jian)。一(yi)個舊(jiu)的(de)(de)鎳鎘電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)很(hen)可能(neng)(neng)要花(hua)上48個小時(shi)才能(neng)(neng)給新款高(gao)電(dian)(dian)(dian)(dian)容的(de)(de)鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)分充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)！這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)幾(ji)乎不可能(neng)(neng)損壞鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)，除非(fei)把(ba)鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)放在充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)里長達一(yi)個星期，但(dan)是這樣就(jiu)不方便使用了(le)。如果你有這種類型的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，應該根據我們上面的(de)(de)公式簡單的(de)(de)把(ba)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)算出來 

　　但是(shi)，最終我(wo)們可(ke)(ke)能選擇(ze)一(yi)款更(geng)舊(jiu)的(de)(de)鎳(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)：疾(ji)(ji)速(su)(su)充(chong)(chong)(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)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，不需要(yao)多余的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路。因為(wei)一(yi)旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)滿后，充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)期就(jiu)(jiu)停止了，被記(ji)錄下來。如(ru)果(guo)鎳(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)將在(zai)(zai)2個(ge)小時以內給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)分充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，那么它就(jiu)(jiu)可(ke)(ke)以說是(shi)疾(ji)(ji)速(su)(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。在(zai)(zai)這個(ge)情況(kuang)中，唯一(yi)的(de)(de)風險就(jiu)(jiu)是(shi)：更(geng)舊(jiu)的(de)(de)疾(ji)(ji)速(su)(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)可(ke)(ke)能會(hui)給鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)過度充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。如(ru)果(guo)在(zai)(zai)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)期中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)變(bian)得很熱，那么這就(jiu)(jiu)是(shi)過度充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)征兆（一(yi)般(ban)來說，當鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)被充(chong)(chong)(chong)(chong)(chong)分充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后，就(jiu)(jiu)會(hui)變(bian)得溫暖一(yi)些，特別是(shi)使用疾(ji)(ji)速(su)(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時）。如(ru)果(guo)鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)變(bian)得太(tai)熱，我(wo)們無法及時處理(li)，當持續20或30分鐘后，鎳(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)就(jiu)(jiu)很可(ke)(ke)能對鎳(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)過度充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)了，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)壽命(ming)就(jiu)(jiu)會(hui)縮短。如(ru)果(guo)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)專為(wei)需迅速(su)(su)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)收音機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，你很可(ke)(ke)能遇(yu)見到(dao)這類充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。我(wo)們建(jian)議不要(yao)使用鎳(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)疾(ji)(ji)速(su)(su)充(chong)(chong)(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)(chi)(chi)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。
