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)常都有較高的控制精密度，能夠對鋰離子(zi)電池進行(xing)恒(heng)流恒(heng)壓充電.

   1. 鋰(li)(li)(li)電池(chi)充(chong)電器的(de)工(gong)作(zuo)選(xuan)擇與被(bei)(bei)充(chong)電池(chi)一致。如(ru)果充(chong)電器工(gong)作(zuo)于(yu)鋰(li)(li)(li)電池(chi)狀(zhuang)(zhuang)態而去(qu)充(chong)鎳(nie)氫或鎳(nie)鎘電池(chi)，則(ze)電池(chi)充(chong)不滿，會(hui)大大減少工(gong)作(zuo)時間(jian)。如(ru)果充(chong)電器工(gong)作(zuo)于(yu)鎳(nie)電池(chi)狀(zhuang)(zhuang)態而去(qu)充(chong)鋰(li)(li)(li)離子(zi)電池(chi)，則(ze)鋰(li)(li)(li)電池(chi)被(bei)(bei)過充(chong)，將嚴重(zhong)影響(xiang)電池(chi)的(de)壽命。

   2. 要了解(jie)所用(yong)鋰電(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)器充(chong)(chong)滿點亮時電(dian)(dian)池(chi)是否真的已充(chong)(chong)滿。有(you)些(xie)充(chong)(chong)電(dian)(dian)器見(jian)(jian)到(dao)充(chong)(chong)滿指示燈亮即可(ke)(ke)將鋰電(dian)(dian)池(chi)取(qu)下，有(you)些(xie)充(chong)(chong)電(dian)(dian)器要見(jian)(jian)到(dao)指示燈全亮才可(ke)(ke)將電(dian)(dian)池(chi)取(qu)下。
