NiMH是鎳 – 金屬氫化物的縮寫。鎳氫電池是我們在消費電子產品中最常見的可充電電池。由于其優越的化學性質，鎳氫電池已經取代了鎳鎘電池應用。由于鎳氫不使用鎘（在電池應用中使用有毒化學品）并且另外沒有困擾NiCD的相同存儲器問題，鎳氫電池是更好的選擇。同時，便攜式高功耗解決方案是電池應用中最受歡迎的解決方案之一。今天，我們來了解一下使用鎳氫電池的技巧！

鎳氫電池有哪些分類？

我們(men)通(tong)常(chang)(chang)看(kan)(kan)到鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組由(you)多個串聯的單(dan)個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組成(cheng)。與聚合物鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)（LiPO）相比，鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使用更安全(quan)。每個單(dan)獨電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)1.2V，這意味著我們(men)看(kan)(kan)到鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)1.2V的倍數。特別是，我們(men)提(ti)供1.2,2.4,3.6,4.8,6.0,7.2和8.4伏電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)組。無論電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的物理(li)尺寸(cun)如何，每個鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的額(e)定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)都(dou)為(wei)1.2V。電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的物理(li)尺寸(cun)表示電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的容量。通(tong)常(chang)(chang)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)越大(da)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的mAh就(jiu)越大(da)。

鎳氫電池的使用領域有哪些？為什么？

如上所述，鎳氫電池(chi)非常適合(he)短期(qi)（<30天）高耗水量。我們看到鎳氫電池(chi)使(shi)用的一些(xie)消費者(zhe)應用是數碼相機，通信設備，個人(ren)化妝品設備和筆記本電池(chi)等。

鎳氫電池怎么使用才是最佳的？

鎳氫電池可能存在一些缺陷，主要是它們會自行放電。當電池不使用時，它將慢慢耗盡其電量，如果電池剩余時間足夠長，則電池可能會永久損壞。對鎳氫電池耗盡的粗略估計是電池電量的20％將在充電后的前24小時內耗盡，此后每30天還會耗盡10％。 

如何為鎳氫電池充電？

要為鎳(nie)(nie)氫電(dian)(dian)(dian)池充電(dian)(dian)(dian)，我(wo)們需要一(yi)個(ge)特定的充電(dian)(dian)(dian)器，因(yin)為使用(yong)不正確的電(dian)(dian)(dian)池充電(dian)(dian)(dian)方法可能會使電(dian)(dian)(dian)池無法使用(yong)。注意的是，保只對鎳(nie)(nie)氫電(dian)(dian)(dian)池充電(dian)(dian)(dian)的時(shi)間少(shao)于(yu)20小時(shi)，因(yin)為長時(shi)間充電(dian)(dian)(dian)可能會損(sun)壞電(dian)(dian)(dian)池！

鎳氫電池充電多少次？

通常(chang)情況下，預計標準鎳氫電(dian)(dian)池(chi)(chi)(chi)的(de)充電(dian)(dian)/放(fang)電(dian)(dian)周期(qi)為(wei)(wei)2000次，但不同(tong)(tong)的(de)里程可能會有所不同(tong)(tong)。這是因為(wei)(wei)每(mei)個電(dian)(dian)池(chi)(chi)(chi)都不相同(tong)(tong)。電(dian)(dian)池(chi)(chi)(chi)的(de)使用(yong)也可以決定電(dian)(dian)池(chi)(chi)(chi)存活的(de)周期(qi)數。總而言之，電(dian)(dian)池(chi)(chi)(chi)的(de)2000次（或左(zuo)右(you)）周期(qi)對于可充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)來說是相當可觀的(de)！

鎳氫電池的充電注意事項？

為(wei)(wei)了保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)使(shi)用壽命，您(nin)應該(gai)記住幾個注意事(shi)項：涓流(liu)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)是您(nin)可(ke)以(yi)(yi)為(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)最安全的(de)方法。為(wei)(wei)此(ci)，請確(que)保(bao)以(yi)(yi)盡可(ke)能(neng)低的(de)速(su)(su)率充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，總充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間低于20小時，并在此(ci)時取(qu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。這種(zhong)方法基本(ben)上是以(yi)(yi)不會(hui)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過度(du)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)速(su)(su)度(du)為(wei)(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，但要(yao)保(bao)持充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態。不要(yao)對(dui) 鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)過度(du)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。簡而言之，一旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)就會(hui)停止充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。有幾種(zhong)方法可(ke)以(yi)(yi)知(zhi)道電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)何時充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，現在市面上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器都(dou)是“智(zhi)能(neng)”的(de)，可(ke)以(yi)(yi)幫助檢測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓/溫(wen)度(du)的(de)微(wei)小變化(hua)，可(ke)以(yi)(yi)指(zhi)示充(chong)(chong)滿(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。

鎳氫電池的儲存問題？

最初，基(ji)于鎳(nie)(nie)的(de)(de)電(dian)(dian)池(chi)(chi)(chi)和(he)存儲器存在廣泛的(de)(de)問題。基(ji)本(ben)上(shang)，如(ru)(ru)果(guo)在充電(dian)(dian)前沒(mei)(mei)(mei)有完(wan)全耗(hao)盡電(dian)(dian)池(chi)(chi)(chi)，隨(sui)著(zhu)時(shi)間的(de)(de)推移，這一部分電(dian)(dian)池(chi)(chi)(chi)容量也將會慢慢耗(hao)盡。但是(shi)，現在的(de)(de)鎳(nie)(nie)氫電(dian)(dian)池(chi)(chi)(chi)沒(mei)(mei)(mei)有這些(xie)問題，但如(ru)(ru)果(guo)你沒(mei)(mei)(mei)有完(wan)全放電(dian)(dian)，你仍然可(ke)以(yi)看到同樣的(de)(de)效(xiao)果(guo)。通過“鍛煉”電(dian)(dian)池(chi)(chi)(chi)可(ke)以(yi)恢(hui)復較(jiao)新的(de)(de)鎳(nie)(nie)氫（對電(dian)(dian)池(chi)(chi)(chi)完(wan)全充電(dian)(dian)和(he)放電(dian)(dian)幾次）。

鎳氫電池是否可代替堿性電池？

這是完全可(ke)以(yi)的(de)(de)！如(ru)果你正在(zai)使用堿(jian)性(xing)(xing)電池(chi)(chi)，是可(ke)以(yi)拿起(qi)一些鎳氫電池(chi)(chi)來代(dai)替(ti)它(ta)們。堿(jian)性(xing)(xing)電池(chi)(chi)在(zai)使用時經歷的(de)(de)電壓降抵消了(le)電壓差（堿(jian)性(xing)(xing)1.5v，NiMH 1.2V）。每個電池(chi)(chi)都有(you)點(dian)不同，電池(chi)(chi)的(de)(de)質量也是不同的(de)(de)。在(zai)第一次充電之前，請務必查看(kan)電池(chi)(chi)數據(ju)表(biao)/產品(pin)信息！如(ru)果有(you)什么更好的(de)(de)意見及建議，歡迎聯系小(xiao)格。
