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)都有較(jiao)高的控制精密度，能夠對鋰離(li)子電(dian)池進(jin)行恒流(liu)恒壓(ya)充電(dian).

   1. 鋰(li)(li)電(dian)池(chi)(chi)充電(dian)器的工作(zuo)選擇(ze)與(yu)被(bei)充電(dian)池(chi)(chi)一致。如果充電(dian)器工作(zuo)于鋰(li)(li)電(dian)池(chi)(chi)狀(zhuang)態而(er)去充鎳(nie)氫或鎳(nie)鎘電(dian)池(chi)(chi)，則電(dian)池(chi)(chi)充不(bu)滿，會大大減少工作(zuo)時間。如果充電(dian)器工作(zuo)于鎳(nie)電(dian)池(chi)(chi)狀(zhuang)態而(er)去充鋰(li)(li)離子電(dian)池(chi)(chi)，則鋰(li)(li)電(dian)池(chi)(chi)被(bei)過充，將嚴重影(ying)響電(dian)池(chi)(chi)的壽命。

   2. 要了解所(suo)用(yong)鋰電(dian)池充(chong)(chong)(chong)電(dian)器充(chong)(chong)(chong)滿點亮時電(dian)池是否(fou)真的已充(chong)(chong)(chong)滿。有些(xie)充(chong)(chong)(chong)電(dian)器見(jian)到充(chong)(chong)(chong)滿指(zhi)示燈亮即可將鋰電(dian)池取下，有些(xie)充(chong)(chong)(chong)電(dian)器要見(jian)到指(zhi)示燈全亮才可將電(dian)池取下。
