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(chang)都(dou)有較高的控制精密度(du)，能夠對(dui)鋰離子(zi)電池進(jin)行恒流(liu)恒壓(ya)充(chong)電.

   1. 鋰電(dian)池(chi)(chi)(chi)(chi)充(chong)電(dian)器(qi)(qi)(qi)的(de)工作選擇與被(bei)充(chong)電(dian)池(chi)(chi)(chi)(chi)一致。如(ru)果(guo)充(chong)電(dian)器(qi)(qi)(qi)工作于鋰電(dian)池(chi)(chi)(chi)(chi)狀(zhuang)態(tai)而去充(chong)鎳氫(qing)或鎳鎘電(dian)池(chi)(chi)(chi)(chi)，則(ze)電(dian)池(chi)(chi)(chi)(chi)充(chong)不(bu)滿，會大(da)大(da)減少(shao)工作時間(jian)。如(ru)果(guo)充(chong)電(dian)器(qi)(qi)(qi)工作于鎳電(dian)池(chi)(chi)(chi)(chi)狀(zhuang)態(tai)而去充(chong)鋰離子電(dian)池(chi)(chi)(chi)(chi)，則(ze)鋰電(dian)池(chi)(chi)(chi)(chi)被(bei)過(guo)充(chong)，將嚴重影響電(dian)池(chi)(chi)(chi)(chi)的(de)壽命。

   2. 要了解所用鋰(li)電(dian)(dian)(dian)池充電(dian)(dian)(dian)器(qi)充滿點亮(liang)時電(dian)(dian)(dian)池是否真的已充滿。有些(xie)(xie)充電(dian)(dian)(dian)器(qi)見到充滿指示(shi)燈(deng)亮(liang)即可(ke)將(jiang)鋰(li)電(dian)(dian)(dian)池取下，有些(xie)(xie)充電(dian)(dian)(dian)器(qi)要見到指示(shi)燈(deng)全亮(liang)才可(ke)將(jiang)電(dian)(dian)(dian)池取下。
