很多人在使用電池充電器的時候都有以下兩點(dian)疑問： 1.新買的充(chong)電電池充(chong)電要(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)電(dian)(dian)(dian)(dian)(dian)了。當(dang)遇見這種(zhong)問(wen)題(ti)的(de)時(shi)(shi)候，你(ni)只要將(jiang)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)移開充(chong)電(dian)(dian)(dian)(dian)(dian)器，然后在放進(jin)繼續充(chong)電(dian)(dian)(dian)(dian)(dian)。這對于新充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)是很(hen)正常的(de)現象(xiang)，不(bu)是你(ni)購買到不(bu)良的(de)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)（鎳氫、鋰離子電(dian)(dian)(dian)(dian)(dian)池(chi)）。一般來說(shuo)對充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)時(shi)(shi)間不(bu)能太久(jiu)，最多12小時(shi)(shi)就(jiu)足(zu)夠，如果一旦過度充(chong)電(dian)(dian)(dian)(dian)(dian)就(jiu)會對充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)造成損壞。 2.如何計算充(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間？

　　充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)（小時(shi)）=充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池容量（mAh）/充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流（mA）*1.5的(de)(de)(de)(de)系數假如你用(yong)1600mAh的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器用(yong)400mA的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，則(ze)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)為(wei):600/400*1.5=6小時(shi)（注意：這種方法不(bu)(bu)適用(yong)新購(gou)買或長(chang)期未使(shi)用(yong)的(de)(de)(de)(de)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池）鎳(nie)(nie)氫充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池和鋰離(li)子充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池其(qi)實(shi)也是有記憶效(xiao)(xiao)應(ying)，使(shi)用(yong)起(qi)來真的(de)(de)(de)(de)不(bu)(bu)用(yong)放電(dian)(dian)(dian)(dian)(dian)嗎？其(qi)實(shi)上(shang)鎳(nie)(nie)氫充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池和鋰離(li)子充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)記憶效(xiao)(xiao)應(ying)是十分輕(qing)微的(de)(de)(de)(de)，并不(bu)(bu)值得我們(men)去注意它。

　　（請注意看到這里時，就不要利用充電器的放電(dian)(dian)(dian)功能對鎳(nie)氫充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)和鋰離子充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)進行放電(dian)(dian)(dian)動作(zuo)，尤其是(shi)鋰離子充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)，由于本(ben)身的材質因(yin)數，并不允許電(dian)(dian)(dian)池(chi)(chi)(chi)本(ben)身能夠承受充(chong)電(dian)(dian)(dian)器的強(qiang)制放電(dian)(dian)(dian)。如果你硬(ying)要(yao)對鋰離子充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)進行放電(dian)(dian)(dian)，最終(zhong)將導致電(dian)(dian)(dian)池(chi)(chi)(chi)損(sun)壞。）另(ling)外，你使用(yong)需放電(dian)(dian)(dian)的鎳(nie)鎘充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)，那么(me)建議你，不論(lun)使用(yong)電(dian)(dian)(dian)池(chi)(chi)(chi)的次(ci)數是(shi)否頻繁，最好每隔兩(liang)、三個月左右就(jiu)對鎳(nie)鎘充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)進行一次(ci)充(chong)放電(dian)(dian)(dian)，這樣(yang)可以確保鎳(nie)鎘充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)的記(ji)憶效應對電(dian)(dian)(dian)池(chi)(chi)(chi)的影響減到最低狀(zhuang)態(tai)。
