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控制精密度(du)，能夠對(dui)鋰(li)離子電(dian)池進行恒流恒壓充電(dian).

   1. 鋰電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)器的工(gong)作(zuo)(zuo)選擇與被充(chong)電(dian)(dian)(dian)(dian)池一致(zhi)。如果(guo)充(chong)電(dian)(dian)(dian)(dian)器工(gong)作(zuo)(zuo)于鋰電(dian)(dian)(dian)(dian)池狀態(tai)而(er)(er)去(qu)充(chong)鎳氫或鎳鎘電(dian)(dian)(dian)(dian)池，則(ze)電(dian)(dian)(dian)(dian)池充(chong)不滿，會大(da)大(da)減(jian)少工(gong)作(zuo)(zuo)時間。如果(guo)充(chong)電(dian)(dian)(dian)(dian)器工(gong)作(zuo)(zuo)于鎳電(dian)(dian)(dian)(dian)池狀態(tai)而(er)(er)去(qu)充(chong)鋰離(li)子電(dian)(dian)(dian)(dian)池，則(ze)鋰電(dian)(dian)(dian)(dian)池被過充(chong)，將嚴重影(ying)響電(dian)(dian)(dian)(dian)池的壽命(ming)。

   2. 要了(le)解所用鋰(li)電(dian)(dian)池(chi)充(chong)電(dian)(dian)器(qi)充(chong)滿(man)(man)點(dian)亮時電(dian)(dian)池(chi)是否真的已充(chong)滿(man)(man)。有些充(chong)電(dian)(dian)器(qi)見到充(chong)滿(man)(man)指示(shi)燈(deng)亮即可(ke)將鋰(li)電(dian)(dian)池(chi)取下，有些充(chong)電(dian)(dian)器(qi)要見到指示(shi)燈(deng)全亮才可(ke)將電(dian)(dian)池(chi)取下。
