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(ji)本都是(shi)根(gen)據各(ge)個產品(pin)單獨(du)封(feng)裝(zhuang)，互不(bu)通用的(de)(de)(de)，因此各(ge)個產品(pin)也(ye)提供各(ge)自的(de)(de)(de)充(chong)電(dian)(dian)(dian)設備，互不(bu)通用，在使(shi)(shi)用時只(zhi)要遵循各(ge)自的(de)(de)(de)說明書(shu)使(shi)(shi)用即可。所以本篇對電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)的(de)(de)(de)介紹主要是(shi)指鎳(nie)鎘電(dian)(dian)(dian)池和(he)(he)(he)鎳(nie)氫電(dian)(dian)(dian)池。對鎳(nie)隔(ge)電(dian)(dian)(dian)池和(he)(he)(he)鎳(nie)氫電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)有兩(liang)種方(fang)式，就是(shi)我們大家(jia)所熟(shu)知的(de)(de)(de)“快(kuai)充(chong)”和(he)(he)(he)“慢(man)(man)充(chong)”。快(kuai)充(chong)和(he)(he)(he)慢(man)(man)充(chong)是(shi)充(chong)電(dian)(dian)(dian)的(de)(de)(de)一(yi)個重(zhong)要概念，只(zhi)有了解了快(kuai)充(chong)和(he)(he)(he)慢(man)(man)充(chong)才(cai)能正確掌握充(chong)電(dian)(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)電(dian)電(dian)流(liu)有200mA，是(shi)不(bu)是(shi)快(kuai)(kuai)充(chong)？這個答(da)案并不(bu)絕對(dui)，應該回答(da)對(dui)于(yu)某(mou)些(xie)電(dian)池來(lai)說，它是(shi)快(kuai)(kuai)充(chong)，而對(dui)于(yu)某(mou)些(xie)電(dian)池來(lai)說，它只是(shi)慢充(chong)。那我們究(jiu)竟怎樣來(lai)判別快(kuai)(kuai)充(chong)還是(shi)慢充(chong)呢？

　　例如一(yi)節(jie)5號鎳氫電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)容量(liang)為1200mAH，而(er)另一(yi)節(jie)則為1600mAH。把一(yi)節(jie)電(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)容量(liang)稱(cheng)為1C，可見1C只是一(yi)個邏輯概念(nian)，同樣的(de)1C，并不相等。在充(chong)電(dian)(dian)(dian)(dian)時(shi)，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)小(xiao)(xiao)于0.1C時(shi)，稱(cheng)為涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)。顧名思義，是指電(dian)(dian)(dian)(dian)流(liu)(liu)很(hen)小(xiao)(xiao)。一(yi)般而(er)言，涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)能夠把電(dian)(dian)(dian)(dian)池充(chong)的(de)很(hen)足(zu)，而(er)不傷(shang)害電(dian)(dian)(dian)(dian)池壽命，但用涓流(liu)(liu)充(chong)電(dian)(dian)(dian)(dian)所花的(de)時(shi)間實(shi)在太長，因(yin)此很(hen)少單獨使(shi)用，而(er)是和其它充(chong)電(dian)(dian)(dian)(dian)方式(shi)結合(he)使(shi)用。

　　充(chong)電(dian)(dian)電(dian)(dian)流(liu)在0.1C-0.2C之間時(shi)，稱(cheng)為慢速充(chong)電(dian)(dian)。充(chong)電(dian)(dian)電(dian)(dian)流(liu)大于(yu)0.2C，小于(yu)0.8C則是快速充(chong)電(dian)(dian)。而當充(chong)電(dian)(dian)電(dian)(dian)流(liu)大于(yu)0.8C時(shi)，稱(cheng)之為超高(gao)速充(chong)電(dian)(dian)。

　　正因(yin)為(wei)1C是個(ge)邏輯概念(nian)而非絕對(dui)值，因(yin)此根據1C折算的快(kuai)充(chong)慢充(chong)也是一個(ge)相(xiang)對(dui)值。前面例子中提到的200mA充(chong)電(dian)電(dian)流對(dui)于(yu)1200mAH的電(dian)池來說是慢充(chong)，而對(dui)于(yu)700mAH的電(dian)池來說就是快(kuai)充(chong)
