很多人在使用電池充電器的時候都有以下兩點疑問： 1.新買的充(chong)電(dian)電(dian)池充(chong)電(dian)要(yao)8-12小時嗎？

　　不論任何電池都有自我放電的特性，所以當新充電電池到你手中時，這中間可能充電電池已經經過了一段時間的自我放電了。這就是充電電池內部的化學原料已經歷一段時間沒有使用，出現“鈍化”狀態，無法充分發揮化學反應，提供足夠的電壓。在這種情況下，第一次使用充電電池時，一定要將充電電池充滿，讓電壓恢復到原有的水平。事實上，如果你的充電電池長時間沒有使用，也一樣會產生這種“鈍化”現象，而且情況會更嚴重。最好能對充電電池進行3次充放電的過程，將有助充電電池的活化作用。讓充電電池內部的化學物質可以充分發揮應有的效果（鎳鎘電池）。有時新購買的充電電池，放進充電器的時候，會在還沒充飽電之前充電器就(jiu)停止充(chong)(chong)電(dian)(dian)(dian)(dian)了(le)。當遇見(jian)這(zhe)種問題的(de)(de)時候，你只(zhi)要將充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)移(yi)開充(chong)(chong)電(dian)(dian)(dian)(dian)器，然(ran)后在放進繼續充(chong)(chong)電(dian)(dian)(dian)(dian)。這(zhe)對于新充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是很(hen)正(zheng)常的(de)(de)現(xian)象，不是你購買到(dao)不良的(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)（鎳氫、鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)）。一般來說對充(chong)(chong)電(dian)(dian)(dian)(dian)的(de)(de)時間不能太久，最多12小時就(jiu)足夠，如果(guo)一旦(dan)過度(du)充(chong)(chong)電(dian)(dian)(dian)(dian)就(jiu)會對充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)造(zao)成損壞。 2.如何計算充(chong)(chong)電(dian)(dian)(dian)(dian)時間？

　　充(chong)電(dian)(dian)(dian)時間(jian)（小(xiao)時）=充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)容量（mAh）/充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(liu)（mA）*1.5的系數假(jia)如你用(yong)1600mAh的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)，充(chong)電(dian)(dian)(dian)器用(yong)400mA的電(dian)(dian)(dian)流(liu)(liu)充(chong)電(dian)(dian)(dian)，則(ze)充(chong)電(dian)(dian)(dian)時間(jian)為(wei):600/400*1.5=6小(xiao)時（注意：這種方法(fa)不適用(yong)新購買或長期未(wei)使(shi)用(yong)的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)）鎳氫充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)和(he)鋰(li)離(li)子充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)其(qi)實也是(shi)有記憶(yi)效(xiao)應，使(shi)用(yong)起來真的不用(yong)放電(dian)(dian)(dian)嗎？其(qi)實上鎳氫充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)和(he)鋰(li)離(li)子充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)的記憶(yi)效(xiao)應是(shi)十分輕微的，并不值得我們去(qu)注意它。

　　（請注意看到這里時，就不要利用充電器的放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)功能對(dui)鎳(nie)氫充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進行放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)動作(zuo)，尤其是鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，由于本身的材質(zhi)因(yin)數，并不(bu)允許(xu)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)本身能夠承(cheng)受充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器的強制放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)。如果(guo)你硬要對(dui)鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進行放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，最終將導致電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損壞。）另外，你使用(yong)需放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)的鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，那么建議(yi)你，不(bu)論使用(yong)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的次(ci)數是否頻繁，最好每隔兩、三個月左右就對(dui)鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進行一次(ci)充(chong)(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)，這樣可以確(que)保鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的記(ji)憶效應(ying)對(dui)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的影(ying)響減到最低狀態。
