鋰離子電池對充電器的要求較高，需要保護電路，所以鋰電池充電器通常都有較高的(de)控制精密度，能夠對鋰離子電池進行恒流恒壓充電.

   1. 鋰電(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)器的工(gong)(gong)作(zuo)選擇與被(bei)充(chong)(chong)電(dian)(dian)(dian)池(chi)一致。如果充(chong)(chong)電(dian)(dian)(dian)器工(gong)(gong)作(zuo)于鋰電(dian)(dian)(dian)池(chi)狀態而去(qu)充(chong)(chong)鎳氫(qing)或鎳鎘電(dian)(dian)(dian)池(chi)，則電(dian)(dian)(dian)池(chi)充(chong)(chong)不滿，會大大減少(shao)工(gong)(gong)作(zuo)時(shi)間。如果充(chong)(chong)電(dian)(dian)(dian)器工(gong)(gong)作(zuo)于鎳電(dian)(dian)(dian)池(chi)狀態而去(qu)充(chong)(chong)鋰離子(zi)電(dian)(dian)(dian)池(chi)，則鋰電(dian)(dian)(dian)池(chi)被(bei)過充(chong)(chong)，將嚴重影響電(dian)(dian)(dian)池(chi)的壽命(ming)。

   2. 要了(le)解所用鋰電(dian)(dian)池充(chong)(chong)電(dian)(dian)器充(chong)(chong)滿(man)點亮時電(dian)(dian)池是否真的已充(chong)(chong)滿(man)。有些充(chong)(chong)電(dian)(dian)器見到充(chong)(chong)滿(man)指示燈亮即可(ke)將鋰電(dian)(dian)池取下，有些充(chong)(chong)電(dian)(dian)器要見到指示燈全亮才(cai)可(ke)將電(dian)(dian)池取下。
