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(tong)常(chang)都(dou)有較(jiao)高的控制精密度，能夠對(dui)鋰離(li)子電池(chi)進(jin)行恒流恒壓充電.

   1. 鋰(li)(li)電(dian)(dian)(dian)池充電(dian)(dian)(dian)器的(de)工(gong)(gong)(gong)(gong)作選擇與被充電(dian)(dian)(dian)池一致。如(ru)果充電(dian)(dian)(dian)器工(gong)(gong)(gong)(gong)作于鋰(li)(li)電(dian)(dian)(dian)池狀態而(er)去充鎳(nie)(nie)氫或鎳(nie)(nie)鎘電(dian)(dian)(dian)池，則電(dian)(dian)(dian)池充不(bu)滿，會大大減少工(gong)(gong)(gong)(gong)作時間。如(ru)果充電(dian)(dian)(dian)器工(gong)(gong)(gong)(gong)作于鎳(nie)(nie)電(dian)(dian)(dian)池狀態而(er)去充鋰(li)(li)離子(zi)電(dian)(dian)(dian)池，則鋰(li)(li)電(dian)(dian)(dian)池被過充，將(jiang)嚴重影響(xiang)電(dian)(dian)(dian)池的(de)壽命。

   2. 要了解所(suo)用鋰(li)電(dian)(dian)池(chi)(chi)充(chong)(chong)電(dian)(dian)器充(chong)(chong)滿(man)點亮時電(dian)(dian)池(chi)(chi)是否(fou)真的已充(chong)(chong)滿(man)。有些充(chong)(chong)電(dian)(dian)器見到(dao)充(chong)(chong)滿(man)指(zhi)示燈(deng)亮即可將鋰(li)電(dian)(dian)池(chi)(chi)取下(xia)，有些充(chong)(chong)電(dian)(dian)器要見到(dao)指(zhi)示燈(deng)全亮才(cai)可將電(dian)(dian)池(chi)(chi)取下(xia)。
