充電是使用充電電池的重要步驟。適當合理的充電對延長電池壽命很有好處，而野蠻胡亂充電將會對電池壽命有很大影響。鋰電池基本都是(shi)根據各(ge)個產品(pin)單獨(du)封裝，互不通用(yong)(yong)的(de)(de)，因此各(ge)個產品(pin)也提供各(ge)自的(de)(de)充(chong)電(dian)(dian)設(she)備，互不通用(yong)(yong)，在使用(yong)(yong)時只(zhi)要遵循(xun)各(ge)自的(de)(de)說明書使用(yong)(yong)即可。所(suo)以本篇對電(dian)(dian)池(chi)充(chong)電(dian)(dian)的(de)(de)介紹(shao)主要是(shi)指鎳(nie)鎘電(dian)(dian)池(chi)和(he)(he)(he)鎳(nie)氫(qing)電(dian)(dian)池(chi)。對鎳(nie)隔(ge)電(dian)(dian)池(chi)和(he)(he)(he)鎳(nie)氫(qing)電(dian)(dian)池(chi)充(chong)電(dian)(dian)有(you)兩種方式，就是(shi)我們大家所(suo)熟(shu)知的(de)(de)“快(kuai)充(chong)”和(he)(he)(he)“慢充(chong)”。快(kuai)充(chong)和(he)(he)(he)慢充(chong)是(shi)充(chong)電(dian)(dian)的(de)(de)一個重要概念，只(zhi)有(you)了(le)解了(le)快(kuai)充(chong)和(he)(he)(he)慢充(chong)才能正確掌握充(chong)電(dian)(dian)。

　　首先，快充和慢充是個相對的概念。有人曾問，充電器充(chong)(chong)電(dian)電(dian)流(liu)有200mA，是(shi)不是(shi)快充(chong)(chong)？這個(ge)答案并不絕對(dui)，應該回答對(dui)于(yu)(yu)某些(xie)電(dian)池來(lai)說，它(ta)(ta)是(shi)快充(chong)(chong)，而(er)對(dui)于(yu)(yu)某些(xie)電(dian)池來(lai)說，它(ta)(ta)只是(shi)慢充(chong)(chong)。那我們究竟(jing)怎樣來(lai)判別快充(chong)(chong)還是(shi)慢充(chong)(chong)呢(ni)？

　　例如一節5號鎳氫電(dian)(dian)(dian)池的電(dian)(dian)(dian)容量(liang)為1200mAH，而另一節則為1600mAH。把一節電(dian)(dian)(dian)池的電(dian)(dian)(dian)容量(liang)稱(cheng)為1C，可見1C只(zhi)是(shi)一個邏輯概(gai)念，同樣的1C，并不相等。在充(chong)電(dian)(dian)(dian)時(shi)，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)小(xiao)于(yu)0.1C時(shi)，稱(cheng)為涓流(liu)充(chong)電(dian)(dian)(dian)。顧名思義，是(shi)指(zhi)電(dian)(dian)(dian)流(liu)很小(xiao)。一般而言，涓流(liu)充(chong)電(dian)(dian)(dian)能夠把電(dian)(dian)(dian)池充(chong)的很足，而不傷害(hai)電(dian)(dian)(dian)池壽命(ming)，但用(yong)涓流(liu)充(chong)電(dian)(dian)(dian)所花的時(shi)間實在太長，因此很少單獨使(shi)用(yong)，而是(shi)和其它充(chong)電(dian)(dian)(dian)方(fang)式結合使(shi)用(yong)。

　　充(chong)(chong)電(dian)電(dian)流(liu)在(zai)0.1C-0.2C之間時(shi)，稱(cheng)為(wei)慢速充(chong)(chong)電(dian)。充(chong)(chong)電(dian)電(dian)流(liu)大于(yu)0.2C，小于(yu)0.8C則(ze)是快速充(chong)(chong)電(dian)。而(er)當充(chong)(chong)電(dian)電(dian)流(liu)大于(yu)0.8C時(shi)，稱(cheng)之為(wei)超高速充(chong)(chong)電(dian)。

　　正因(yin)為1C是(shi)個邏輯概念(nian)而非絕對(dui)(dui)值，因(yin)此根(gen)據1C折算的(de)快充慢充也是(shi)一(yi)個相(xiang)對(dui)(dui)值。前面(mian)例子(zi)中提到的(de)200mA充電(dian)電(dian)流對(dui)(dui)于1200mAH的(de)電(dian)池(chi)來說是(shi)慢充，而對(dui)(dui)于700mAH的(de)電(dian)池(chi)來說就(jiu)是(shi)快充
