很多人在使用電池充電器的(de)時(shi)候都有以下兩點疑問(wen)： 1.新買的(de)充電(dian)電(dian)池充電(dian)要8-12小時(shi)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(zhi)充(chong)電(dian)(dian)了。當遇見這(zhe)種問(wen)題的時(shi)(shi)候，你只要將充(chong)電(dian)(dian)電(dian)(dian)池(chi)移開充(chong)電(dian)(dian)器，然后在(zai)放進繼(ji)續充(chong)電(dian)(dian)。這(zhe)對于新充(chong)電(dian)(dian)電(dian)(dian)池(chi)是很(hen)正(zheng)常的現(xian)象，不(bu)是你購買到不(bu)良的充(chong)電(dian)(dian)電(dian)(dian)池(chi)（鎳(nie)氫、鋰離子電(dian)(dian)池(chi)）。一般來說對充(chong)電(dian)(dian)的時(shi)(shi)間不(bu)能太久(jiu)，最多12小時(shi)(shi)就足夠(gou)，如果一旦(dan)過度充(chong)電(dian)(dian)就會對充(chong)電(dian)(dian)電(dian)(dian)池(chi)造(zao)成損壞。 2.如何(he)計算(suan)充(chong)電(dian)(dian)時(shi)(shi)間？

　　充(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間（小時(shi)(shi)(shi)）=充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)容量（mAh）/充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流（mA）*1.5的(de)系數假如你用1600mAh的(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)，充(chong)電(dian)(dian)(dian)(dian)器(qi)用400mA的(de)電(dian)(dian)(dian)(dian)流充(chong)電(dian)(dian)(dian)(dian)，則(ze)充(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)(shi)間為(wei):600/400*1.5=6小時(shi)(shi)(shi)（注意(yi)：這種方法不適用新購(gou)買(mai)或長期(qi)未使用的(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)）鎳(nie)氫充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)鋰(li)離子充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)其實(shi)(shi)也是有(you)記憶效(xiao)(xiao)應(ying)，使用起來真的(de)不用放電(dian)(dian)(dian)(dian)嗎(ma)？其實(shi)(shi)上鎳(nie)氫充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)鋰(li)離子充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)記憶效(xiao)(xiao)應(ying)是十分輕(qing)微的(de)，并不值得我(wo)們(men)去注意(yi)它。

　　（請注意看到這里時，就不要利用充電器的(de)放電(dian)(dian)(dian)功能對鎳(nie)氫充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)和(he)鋰(li)離子充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進(jin)行(xing)放電(dian)(dian)(dian)動作，尤(you)其是鋰(li)離子充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，由(you)于本身(shen)(shen)的(de)材質因數，并不允許電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)本身(shen)(shen)能夠承受(shou)充(chong)(chong)電(dian)(dian)(dian)器的(de)強制(zhi)放電(dian)(dian)(dian)。如果(guo)你硬要對鋰(li)離子充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進(jin)行(xing)放電(dian)(dian)(dian)，最(zui)終將導致電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)損壞(huai)。）另外(wai)，你使(shi)用(yong)(yong)需放電(dian)(dian)(dian)的(de)鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，那么建議你，不論使(shi)用(yong)(yong)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)次數是否頻(pin)繁，最(zui)好每隔兩、三(san)個月左右就對鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)進(jin)行(xing)一次充(chong)(chong)放電(dian)(dian)(dian)，這(zhe)樣可(ke)以確(que)保(bao)鎳(nie)鎘(ge)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)記憶(yi)效應對電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)影響減到最(zui)低(di)狀態(tai)。
