我們僅討論最常用的鎳氫電池和鎳鎘電池充電器，不包(bao)括最(zui)新的鉛(qian)酸電池和鋰(li)離子電池充(chong)電器(qi)。

一、疾速充(chong)電器(qi)和快速充(chong)電器(qi)的區別是什么？

這兩者(zhe)的(de)比較實際上是(shi)沒有任何意(yi)義的(de)。在電(dian)池(chi)(chi)行(xing)業(ye)內(nei)，對這兩種(zhong)充(chong)(chong)(chong)(chong)電(dian)器沒有明確的(de)界定。因此制(zhi)造商們(men)(men)也經(jing)常把它們(men)(men)弄(nong)混。有一個問題(ti)就(jiu)是(shi)，充(chong)(chong)(chong)(chong)滿(man)(man)(man)一節電(dian)池(chi)(chi)的(de)時(shi)間(jian)依賴于(yu)被充(chong)(chong)(chong)(chong)電(dian)的(de)電(dian)池(chi)(chi)的(de)容量。一個需(xu)花(hua)1小時(shi)充(chong)(chong)(chong)(chong)滿(man)(man)(man)1節標準容量的(de)AAA鎳鎘(ge)電(dian)池(chi)(chi)（180 mAh）充(chong)(chong)(chong)(chong)電(dian)器，可能(neng)需(xu)要8小時(shi)才能(neng)充(chong)(chong)(chong)(chong)滿(man)(man)(man)1節高容量的(de)鎳氫電(dian)池(chi)(chi)（1500 mAh）。最好(hao)的(de)辦法是(shi)忽略這些差異，粗略地(di)計算一下充(chong)(chong)(chong)(chong)電(dian)器充(chong)(chong)(chong)(chong)滿(man)(man)(man)電(dian)池(chi)(chi)所需(xu)的(de)時(shi)間(jian)。

二、每次要花多長(chang)時(shi)間才能把電池充滿？

我(wo)們可(ke)以(yi)(yi)很容(rong)易計(ji)算(suan)出充(chong)(chong)(chong)電(dian)器(qi)所花的時(shi)(shi)間。用電(dian)池的容(rong)量，簡單地除以(yi)(yi)充(chong)(chong)(chong)電(dian)器(qi)的充(chong)(chong)(chong)電(dian)效(xiao)率(lv)，然后增加20%作(zuo)為(wei)無效(xiao)工作(zuo)時(shi)(shi)間。舉個(ge)(ge)例子(zi)，使用一(yi)個(ge)(ge)充(chong)(chong)(chong)電(dian)率(lv)為(wei)500mA的充(chong)(chong)(chong)電(dian)器(qi)大約需(xu)4小(xiao)時(shi)(shi)才(cai)能充(chong)(chong)(chong)滿一(yi)節有1600mAh的電(dian)池，計(ji)算(suan)式子(zi)為(wei)1600 mAh/500 mA x120%。這(zhe)個(ge)(ge)例子(zi)也許偶然適用于疾速(su)充(chong)(chong)(chong)電(dian)器(qi)對標準5號鎳氫電(dian)池充(chong)(chong)(chong)電(dian)的情況。如(ru)果你覺得這(zhe)個(ge)(ge)太(tai)復雜了，可(ke)以(yi)(yi)使用我(wo)們特別(bie)的電(dian)池充(chong)(chong)(chong)電(dian)時(shi)(shi)間計(ji)ulator.htm。你只需(xu)要輸入上面連續的兩個(ge)(ge)值(zhi)就行(xing)了。然后按Calculate（計(ji)算(suan)），結果就會立即(ji)在hours（小(xiao)時(shi)(shi)）前的窗口中出現(xian)。

三、使用充電(dian)器會對電(dian)池有損害(hai)嗎(ma)（會減少電(dian)池壽(shou)命(ming)或降低電(dian)池使用效果）？

是的(de)(de)。最常(chang)(chang)見的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)失敗就(jiu)(jiu)是充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間過長(chang)，俗稱(cheng)過度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。有(you)(you)一種(zhong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)特別容易(yi)導致過度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，通常(chang)(chang)充(chong)(chong)5小(xiao)(xiao)時以(yi)上（有(you)(you)的(de)(de)是8小(xiao)(xiao)時）電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)就(jiu)(jiu)會報(bao)廢，這種(zhong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)就(jiu)(jiu)是所謂的(de)(de)“疾(ji)速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)”。這種(zhong)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)問題就(jiu)(jiu)是，沒有(you)(you)一個充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)控制裝(zhuang)置。大(da)部分疾(ji)速充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)通常(chang)(chang)設計非(fei)常(chang)(chang)簡單，它(ta)(ta)們一般以(yi)最大(da)速率充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間也比較固定，通常(chang)(chang)是5或8小(xiao)(xiao)時就(jiu)(jiu)充(chong)(chong)滿了(le)。然后，你就(jiu)(jiu)應(ying)該把它(ta)(ta)們關掉，或者轉(zhuan)向特慢(man)的(de)(de)涓流(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)速率。如果你正(zheng)確的(de)(de)使用充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，它(ta)(ta)通常(chang)(chang)對電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)損(sun)害不大(da)。如果沒有(you)(you)正(zheng)確的(de)(de)使用，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)通常(chang)(chang)會以(yi)兩種(zhong)方式縮短電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)壽(shou)命(ming)。

首先，設想把完全充電后和部分充電后的電池放進充電器內。但是充電器并不知道電(dian)池(chi)(chi)內(nei)有電(dian)。因(yin)此(ci)它還(huan)是對電(dian)池(chi)(chi)進行完全充(chong)電(dian)。我們很少見(jian)到把部分(fen)充(chong)電(dian)后的電(dian)池(chi)(chi)放進充(chong)電(dian)器(qi)內(nei)的，因(yin)為這很容易(yi)混淆電(dian)池(chi)(chi)，不經意(yi)間就把充(chong)滿(man)電(dian)后的電(dian)池(chi)(chi)放進充(chong)電(dian)器(qi)內(nei)了。如果你多次對充(chong)滿(man)電(dian)后的電(dian)池(chi)(chi)充(chong)電(dian)，它的性能(neng)就會慢(man)(man)慢(man)(man)降低。

另外(wai)，通常(chang)情況下，充電(dian)(dian)周(zhou)期(qi)不(bu)穩定(ding)，很(hen)容(rong)易被打斷。我們通常(chang)把充電(dian)(dian)器拔開，看看電(dian)(dian)池(chi)(chi)的(de)熱度如何。然后，再把充電(dian)(dian)器插回去(qu)。不(bu)幸(xing)的(de)是，這通常(chang)會(hui)(hui)導致重新開始完(wan)整的(de)充電(dian)(dian)周(zhou)期(qi)，前面的(de)充電(dian)(dian)周(zhou)期(qi)已(yi)經完(wan)成了(le)。這也(ye)常(chang)會(hui)(hui)降低電(dian)(dian)池(chi)(chi)壽命(ming)。

為了避免這些問題，我們可以使用一個智能充電器，它有微處理器控制。智能充電器通常(chang)會決定什么時候(hou)電(dian)池充(chong)滿(man)了電(dian)，然后根(gen)據設(she)計的不同，完全關掉充(chong)電(dian)器或轉向涓(juan)流(liu)充(chong)電(dian)。

四、什(shen)么是(shi)涓(juan)流充(chong)電(dian)（使蓄電(dian)池緩(huan)慢(man)而(er)連(lian)續充(chong)電(dian)的裝(zhuang)備(bei)）？

理論(lun)上說(shuo)，涓流充(chong)(chong)(chong)電(dian)(dian)是(shi)指一種充(chong)(chong)(chong)電(dian)(dian)速率高至使(shi)電(dian)(dian)池完全充(chong)(chong)(chong)滿電(dian)(dian)、低至可避(bi)免過度(du)充(chong)(chong)(chong)電(dian)(dian)的充(chong)(chong)(chong)電(dian)(dian)方(fang)式。維持充(chong)(chong)(chong)電(dian)(dian)也(ye)是(shi)描述涓流充(chong)(chong)(chong)電(dian)(dian)的一種方(fang)式。五、涓流充(chong)(chong)(chong)電(dian)(dian)對電(dian)(dian)池有(you)損害嗎(ma)？

許多(duo)電池制造商建議(yi)不(bu)要(yao)長期使用(yong)涓流充電。

五、涓流充電對電池有損害嗎(ma)？

許多電(dian)池(chi)制造商建議不(bu)要長期使(shi)用涓流充電(dian)。

如果使(shi)用(yong)涓流充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，那么充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)速(su)率(lv)就會(hui)非常低，并且有時斷斷續續。當給電(dian)(dian)(dian)池充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時，最好的(de)智能充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器只能進(jin)行(xing)臨時的(de)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)速(su)率(lv)變化。它(ta)們沒有連續的(de)低速(su)率(lv)充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)功能。一(yi)(yi)些電(dian)(dian)(dian)池經銷商(shang)說，如果進(jin)行(xing)長(chang)期的(de)涓流充(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，只有十(shi)分之一(yi)(yi)的(de)電(dian)(dian)(dian)池能量(liang)不會(hui)受(shou)到傷害。然而，我(wo)們還沒有見到任何廠商(shang)進(jin)行(xing)這樣的(de)測試(shi)。

最(zui)好(hao)還是(shi)把電(dian)(dian)(dian)池完全充滿電(dian)(dian)(dian)，然后(hou)儲存好(hao)。不(bu)要進行(xing)額外的(de)涓流充電(dian)(dian)(dian)。免得出現意外的(de)損(sun)害。

六、疾速充電(dian)(dian)會減少電(dian)(dian)池的壽命嗎？

不是很嚴重。只要使用了一個適當的智能充電器，你就能在約一個小時內把幾乎各種鎳氫電池完全充好電，并且沒有任何損壞，電池壽命也不會有大幅降低，可能減少不到10%。顯然，這總是比使用慢速充電器好多了。然而，只能使用特別設計的鎳氫電池充電器給大多數(shu)鎳氫電(dian)(dian)池(chi)快速(su)(su)充電(dian)(dian)。另外，專為鎳鎘電(dian)(dian)池(chi)充電(dian)(dian)設(she)計的疾速(su)(su)充電(dian)(dian)器很(hen)可能會給鎳氫電(dian)(dian)池(chi)過度充電(dian)(dian)。

七、鎳氫電池充電器和鎳鎘電池充電器的區別是什么？

最大的(de)差別在(zai)(zai)于充(chong)(chong)(chong)電(dian)(dian)(dian)速率（充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)給(gei)電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)的(de)速度(du)），以及充(chong)(chong)(chong)電(dian)(dian)(dian)控制(zhi)（怎么什么時(shi)(shi)(shi)(shi)(shi)候決定停止充(chong)(chong)(chong)電(dian)(dian)(dian)）。 許(xu)多廉價的(de)鎳氫電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)經過(guo)簡單的(de)改造(zao)，就成(cheng)了鎳鎘電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)。通常(chang)，一個(ge)5小(xiao)時(shi)(shi)(shi)(shi)(shi)的(de)鎳鎘電(dian)(dian)(dian)池有一個(ge)開(kai)關，允許(xu)充(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)(shi)(shi)(shi)(shi)間從5個(ge)小(xiao)時(shi)(shi)(shi)(shi)(shi)增加到8個(ge)小(xiao)時(shi)(shi)(shi)(shi)(shi)。 這(zhe)樣，一個(ge)5小(xiao)時(shi)(shi)(shi)(shi)(shi)鎳鎘電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)就變成(cheng)了一個(ge)8小(xiao)時(shi)(shi)(shi)(shi)(shi)鎳氫電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)。我們在(zai)(zai)這(zhe)里并不是(shi)說(shuo)推薦使(shi)用這(zhe)種充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)。然而，一個(ge)定時(shi)(shi)(shi)(shi)(shi)的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)相比一個(ge)智能(neng)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)，生產(chan)成(cheng)本要少一些。如(ru)果電(dian)(dian)(dian)池在(zai)(zai)放電(dian)(dian)(dian)之前進行頻繁的(de)充(chong)(chong)(chong)電(dian)(dian)(dian)（也就是(shi)說(shuo)，電(dian)(dian)(dian)池只使(shi)用了很短的(de)時(shi)(shi)(shi)(shi)(shi)間，然后(hou)又立(li)即被完(wan)全充(chong)(chong)(chong)電(dian)(dian)(dian)），定時(shi)(shi)(shi)(shi)(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)通常(chang)導致過(guo)度(du)充(chong)(chong)(chong)電(dian)(dian)(dian)，或者(zhe)電(dian)(dian)(dian)池損害。

鎳氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)池智(zhi)(zhi)能(neng)(neng)充電(dian)(dian)(dian)(dian)(dian)器(qi)實際上是專門檢(jian)測鎳氫(qing)(qing)電(dian)(dian)(dian)(dian)(dian)池什么時候被充滿了。然后，關(guan)(guan)上開關(guan)(guan)或(huo)轉(zhuan)向涓流充電(dian)(dian)(dian)(dian)(dian)模式。顯然，這要(yao)經過更(geng)復(fu)雜的電(dian)(dian)(dian)(dian)(dian)路(lu)。所(suo)以，這類充電(dian)(dian)(dian)(dian)(dian)器(qi)要(yao)花費更(geng)多的時間與(yu)金(jin)錢。但是，它可(ke)能(neng)(neng)會延長電(dian)(dian)(dian)(dian)(dian)池的壽命。有些智(zhi)(zhi)能(neng)(neng)充電(dian)(dian)(dian)(dian)(dian)器(qi)僅僅比定(ding)時充電(dian)(dian)(dian)(dian)(dian)器(qi)稍微花多一點成本。我們強烈建(jian)議(yi)，當(dang)你想購(gou)買智(zhi)(zhi)能(neng)(neng)充電(dian)(dian)(dian)(dian)(dian)器(qi)時，調查(cha)一下它與(yu)鎳氫(qing)(qing)或(huo)鎳鎘電(dian)(dian)(dian)(dian)(dian)池的兼容(rong)性。

八、能夠使用舊的鎳鎘電池充電器對鎳氫電池充電嗎？

這個問題的答案取決于鎳鎘充(chong)(chong)(chong)電(dian)器(qi)(qi)的類型。由于有這種(zhong)依賴性(xing)，舊(jiu)的鎳鎘電(dian)池充(chong)(chong)(chong)電(dian)器(qi)(qi)可(ke)能(neng)(neng)不會給鎳氫電(dian)池充(chong)(chong)(chong)滿電(dian)（是很(hen)有可(ke)能(neng)(neng)），幾乎不可(ke)能(neng)(neng)發生過度充(chong)(chong)(chong)電(dian)的情況，或適當地給鎳氫電(dian)池充(chong)(chong)(chong)電(dian)（但是它不可(ke)能(neng)(neng)自動(dong)處理，結果(guo)還是要花很(hen)長時間）。讓我(wo)們來看一下這三種(zhong)情況。

許(xu)多“古老”的(de)(de)(de)鎳(nie)鎘電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器是簡單的(de)(de)(de)定(ding)時充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時間都是固定(ding)好了的(de)(de)(de)。時間一到，就(jiu)自動(dong)關上了。不幸的(de)(de)(de)是，因(yin)為(wei)(wei)鎳(nie)鎘電(dian)(dian)(dian)(dian)池(chi)(chi)比鎳(nie)氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)容量小，當使用鎳(nie)鎘電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)時間標(biao)準給鎳(nie)氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)可能會(hui)(hui)提前中(zhong)止。這雖然不會(hui)(hui)傷害電(dian)(dian)(dian)(dian)池(chi)(chi)，但是鎳(nie)氫(qing)(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)肯定(ding)不會(hui)(hui)被完全充(chong)(chong)(chong)滿電(dian)(dian)(dian)(dian)，因(yin)為(wei)(wei)定(ding)時器早就(jiu)固定(ding)好了。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器停(ting)止充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，顯(xian)然是太早了。充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)周(zhou)期(qi)也就(jiu)會(hui)(hui)縮短。

另外，在(zai)更舊(jiu)的鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)之中，有一(yi)(yi)種非常普通的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)，就(jiu)(jiu)是(shi)所(suo)謂(wei)的“通宵(xiao)”充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)。只要充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)接通了電(dian)(dian)(dian)(dian)(dian)源，它的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)速率就(jiu)(jiu)非常低。這(zhe)類(lei)(lei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)能(neng)為鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，但是(shi)它可能(neng)花(hua)上很(hen)(hen)長的時(shi)間。一(yi)(yi)個舊(jiu)的鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)很(hen)(hen)可能(neng)要花(hua)上48個小時(shi)才能(neng)給新款高(gao)電(dian)(dian)(dian)(dian)(dian)容的鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)！這(zhe)類(lei)(lei)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)幾(ji)乎不可能(neng)損壞鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)，除非把(ba)鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)放在(zai)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)里長達一(yi)(yi)個星期，但是(shi)這(zhe)樣就(jiu)(jiu)不方便使用了。如果你有這(zhe)種類(lei)(lei)型的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)，應(ying)該根據(ju)我(wo)們(men)上面的公式簡單的把(ba)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間算(suan)出來

但是，最終我們可(ke)能選擇一(yi)款更舊的鎳(nie)(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)：疾(ji)(ji)(ji)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。它給鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，不(bu)需(xu)(xu)要多(duo)余的電(dian)(dian)(dian)(dian)(dian)(dian)路。因(yin)為一(yi)旦電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)滿后(hou)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期就(jiu)停止了，被記錄下來。如果鎳(nie)(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)將在(zai)2個(ge)小時以(yi)內給電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，那(nei)(nei)么(me)它就(jiu)可(ke)以(yi)說是疾(ji)(ji)(ji)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。在(zai)這個(ge)情況中，唯一(yi)的風險就(jiu)是：更舊的疾(ji)(ji)(ji)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)可(ke)能會(hui)給鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)過度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。如果在(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)周(zhou)(zhou)期中，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)變(bian)(bian)得很熱(re)，那(nei)(nei)么(me)這就(jiu)是過度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的征兆（一(yi)般來說，當鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)被充(chong)(chong)(chong)分(fen)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)后(hou)，就(jiu)會(hui)變(bian)(bian)得溫暖一(yi)些，特(te)別是使(shi)用(yong)疾(ji)(ji)(ji)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時）。如果鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)變(bian)(bian)得太熱(re)，我們無法及時處(chu)理，當持(chi)續20或30分(fen)鐘(zhong)后(hou)，鎳(nie)(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)就(jiu)很可(ke)能對(dui)鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)過度充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)了，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的壽(shou)命就(jiu)會(hui)縮短。如果充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)專為需(xu)(xu)迅速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的收音機電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，你很可(ke)能遇見到這類充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。我們建(jian)議不(bu)要使(shi)用(yong)鎳(nie)(nie)(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)疾(ji)(ji)(ji)速(su)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)給鎳(nie)(nie)(nie)(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。
