很多人在使用電池充電器的時候都(dou)有以(yi)下兩點疑(yi)問： 1.新買(mai)的充電電池充電要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停止充(chong)電(dian)(dian)(dian)了(le)。當(dang)遇見(jian)這種(zhong)問題的時(shi)候(hou)，你(ni)只要將充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)移開充(chong)電(dian)(dian)(dian)器，然后在放進繼續充(chong)電(dian)(dian)(dian)。這對(dui)(dui)于(yu)新充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)是很正常的現象，不(bu)是你(ni)購買到不(bu)良(liang)的充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)（鎳氫、鋰離子電(dian)(dian)(dian)池(chi)）。一般來說對(dui)(dui)充(chong)電(dian)(dian)(dian)的時(shi)間不(bu)能太久，最多12小時(shi)就足夠，如果一旦(dan)過度充(chong)電(dian)(dian)(dian)就會對(dui)(dui)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)造成(cheng)損(sun)壞。 2.如何計算充(chong)電(dian)(dian)(dian)時(shi)間？

　　充(chong)電(dian)(dian)(dian)(dian)(dian)時間（小時）=充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)容量（mAh）/充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流（mA）*1.5的(de)系(xi)數假如你用(yong)1600mAh的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)，充(chong)電(dian)(dian)(dian)(dian)(dian)器用(yong)400mA的(de)電(dian)(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)(dian)，則充(chong)電(dian)(dian)(dian)(dian)(dian)時間為:600/400*1.5=6小時（注意：這種方法(fa)不適用(yong)新購(gou)買(mai)或長(chang)期未使用(yong)的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)）鎳氫(qing)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)和鋰離子(zi)(zi)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)其(qi)(qi)實(shi)(shi)也(ye)是(shi)(shi)有記憶效(xiao)應，使用(yong)起來真的(de)不用(yong)放電(dian)(dian)(dian)(dian)(dian)嗎？其(qi)(qi)實(shi)(shi)上鎳氫(qing)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)和鋰離子(zi)(zi)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)記憶效(xiao)應是(shi)(shi)十(shi)分輕微(wei)的(de)，并(bing)不值得我們去注意它(ta)。
