很多人在使用電池充電器的時候(hou)都有(you)以下兩點疑問(wen)： 1.新買的充電電池充電要8-12小(xiao)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(ting)止充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)了。當遇見這種問題的時(shi)候，你只要將充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)移(yi)開充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器，然后在(zai)放進繼續充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)。這對于新(xin)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)是很正(zheng)常的現(xian)象，不(bu)是你購買到(dao)不(bu)良的充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)（鎳氫、鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)）。一般來說對充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的時(shi)間(jian)不(bu)能太久，最多(duo)12小時(shi)就足夠，如果一旦(dan)過度充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)就會(hui)對充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)造(zao)成(cheng)損壞。 2.如何計算充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)？

　　充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間（小時(shi)(shi)）=充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)容量(liang)（mAh）/充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)（mA）*1.5的(de)(de)系(xi)數假如你用(yong)1600mAh的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器用(yong)400mA的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)間為:600/400*1.5=6小時(shi)(shi)（注(zhu)意：這種方法不適用(yong)新(xin)購買或長期未使(shi)用(yong)的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)）鎳(nie)氫(qing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)和鋰離子(zi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)其實也是有記(ji)憶效(xiao)(xiao)應，使(shi)用(yong)起(qi)來真的(de)(de)不用(yong)放(fang)電(dian)(dian)(dian)(dian)(dian)嗎？其實上鎳(nie)氫(qing)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)和鋰離子(zi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)記(ji)憶效(xiao)(xiao)應是十分輕微的(de)(de)，并不值得我們去(qu)注(zhu)意它。

　　（請注意看到這里時，就不要利用充電器的(de)(de)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)功能對鎳(nie)氫(qing)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和鋰(li)離子充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進行放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)動作，尤其是鋰(li)離子充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，由于本身的(de)(de)材質(zhi)因數(shu)，并不允許電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)本身能夠承受(shou)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)強制放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)。如果(guo)你硬要對鋰(li)離子充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進行放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，最(zui)終將導致電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)損壞。）另外，你使用需(xu)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)鎳(nie)鎘充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，那么建議你，不論(lun)使用電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)次數(shu)是否頻繁，最(zui)好(hao)每隔兩、三個月左右就對鎳(nie)鎘充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進行一次充(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，這樣可以確保鎳(nie)鎘充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)記憶效應(ying)對電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)影響減到最(zui)低狀(zhuang)態。
