很多人在使用電池充電器的時候都有(you)以(yi)下兩點疑(yi)問： 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(jiu)停止充(chong)(chong)(chong)電了。當(dang)遇(yu)見(jian)這種問題的(de)時候，你只要將充(chong)(chong)(chong)電電池(chi)(chi)移開充(chong)(chong)(chong)電器，然后在放(fang)進繼(ji)續充(chong)(chong)(chong)電。這對于(yu)新充(chong)(chong)(chong)電電池(chi)(chi)是很正常的(de)現象，不(bu)是你購(gou)買到不(bu)良的(de)充(chong)(chong)(chong)電電池(chi)(chi)（鎳氫、鋰離子電池(chi)(chi)）。一般來說對充(chong)(chong)(chong)電的(de)時間不(bu)能太(tai)久，最(zui)多12小時就(jiu)足夠(gou)，如(ru)果一旦過度充(chong)(chong)(chong)電就(jiu)會對充(chong)(chong)(chong)電電池(chi)(chi)造(zao)成損壞。 2.如(ru)何計算充(chong)(chong)(chong)電時間？

　　充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)（小(xiao)時）=充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池容量(liang)（mAh）/充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流（mA）*1.5的(de)(de)(de)系數假如(ru)你用(yong)(yong)1600mAh的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池，充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器用(yong)(yong)400mA的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，則充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)為(wei):600/400*1.5=6小(xiao)時（注意：這種方法不(bu)(bu)適用(yong)(yong)新購買或長期(qi)未使用(yong)(yong)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池）鎳氫充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池和鋰離子充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池其實也是有記(ji)憶效應，使用(yong)(yong)起來(lai)真的(de)(de)(de)不(bu)(bu)用(yong)(yong)放電(dian)(dian)(dian)(dian)(dian)嗎？其實上鎳氫充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池和鋰離子充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)記(ji)憶效應是十分輕微的(de)(de)(de)，并不(bu)(bu)值(zhi)得我(wo)們(men)去注意它(ta)。

　　（請注意看到這里時，就不要利用充電器的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)功能(neng)對(dui)鎳(nie)(nie)(nie)氫充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)和鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行(xing)(xing)放電(dian)(dian)(dian)(dian)(dian)(dian)動作，尤其是鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，由于本(ben)身的(de)(de)(de)材質(zhi)因數(shu)，并不(bu)允許電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)本(ben)身能(neng)夠(gou)承(cheng)受(shou)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)強制放電(dian)(dian)(dian)(dian)(dian)(dian)。如(ru)果你(ni)(ni)硬要(yao)對(dui)鋰離(li)子(zi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行(xing)(xing)放電(dian)(dian)(dian)(dian)(dian)(dian)，最終將導致(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)損(sun)壞。）另外，你(ni)(ni)使用(yong)需放電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)鎳(nie)(nie)(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，那(nei)么(me)建議你(ni)(ni)，不(bu)論(lun)使用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)次(ci)數(shu)是否頻繁，最好每隔兩(liang)、三個(ge)月左右就對(dui)鎳(nie)(nie)(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)進(jin)行(xing)(xing)一次(ci)充(chong)(chong)放電(dian)(dian)(dian)(dian)(dian)(dian)，這樣(yang)可以確保鎳(nie)(nie)(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)記憶效應對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)影響(xiang)減(jian)到最低狀態。
