很多人在使用電池充電器的時候都(dou)有(you)以下兩(liang)點疑問： 1.新(xin)買的充電(dian)電(dian)池充電(dian)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止充電(dian)(dian)了。當(dang)遇見這種問(wen)題的時候，你只要將充電(dian)(dian)電(dian)(dian)池(chi)移開充電(dian)(dian)器，然后在放進(jin)繼續(xu)充電(dian)(dian)。這對于(yu)新充電(dian)(dian)電(dian)(dian)池(chi)是很正(zheng)常的現象，不(bu)是你購買到不(bu)良的充電(dian)(dian)電(dian)(dian)池(chi)（鎳氫、鋰(li)離(li)子電(dian)(dian)池(chi)）。一般來(lai)說對充電(dian)(dian)的時間(jian)不(bu)能太久，最多12小時就足夠，如果一旦過度充電(dian)(dian)就會(hui)對充電(dian)(dian)電(dian)(dian)池(chi)造成損壞。 2.如何計(ji)算充電(dian)(dian)時間(jian)？

　　充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間（小時）=充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容量（mAh）/充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流（mA）*1.5的系數假如你用(yong)1600mAh的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器用(yong)400mA的電(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，則充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間為:600/400*1.5=6小時（注(zhu)意(yi)：這種方法不適用(yong)新購買或(huo)長(chang)期未使(shi)用(yong)的充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)）鎳氫充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰離子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)其(qi)實也是(shi)有記憶(yi)(yi)效應，使(shi)用(yong)起來(lai)真的不用(yong)放電(dian)(dian)(dian)(dian)(dian)嗎(ma)？其(qi)實上鎳氫充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰離子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的記憶(yi)(yi)效應是(shi)十(shi)分輕(qing)微的，并不值得我(wo)們去注(zhu)意(yi)它(ta)。

　　（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)(dian)功能(neng)對(dui)(dui)鎳(nie)氫充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰(li)離(li)子(zi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動作，尤其是鋰(li)離(li)子(zi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，由于本身的(de)(de)材(cai)質(zhi)因數(shu)，并不允(yun)許(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)本身能(neng)夠(gou)承(cheng)受(shou)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)強制放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。如果你硬要(yao)對(dui)(dui)鋰(li)離(li)子(zi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，最(zui)終將導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損壞(huai)。）另(ling)外，你使用需放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)鎳(nie)鎘充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，那么(me)建議(yi)你，不論使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)次數(shu)是否(fou)頻繁(fan)，最(zui)好每隔兩、三個(ge)月左右就對(dui)(dui)鎳(nie)鎘充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行一次充(chong)(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，這樣可以確保鎳(nie)鎘充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)記憶效應對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)影響減到(dao)最(zui)低狀態(tai)。
