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(gao)的控制精密度，能夠對鋰離子電(dian)池進(jin)行恒(heng)流(liu)恒(heng)壓充電(dian).

   1. 鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)(dian)器的工作(zuo)選(xuan)擇與被(bei)充電(dian)(dian)(dian)池(chi)(chi)(chi)一(yi)致。如果充電(dian)(dian)(dian)器工作(zuo)于鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)狀態而去(qu)充鎳氫或(huo)鎳鎘電(dian)(dian)(dian)池(chi)(chi)(chi)，則(ze)電(dian)(dian)(dian)池(chi)(chi)(chi)充不(bu)滿，會(hui)大大減(jian)少工作(zuo)時間(jian)。如果充電(dian)(dian)(dian)器工作(zuo)于鎳電(dian)(dian)(dian)池(chi)(chi)(chi)狀態而去(qu)充鋰(li)離子電(dian)(dian)(dian)池(chi)(chi)(chi)，則(ze)鋰(li)電(dian)(dian)(dian)池(chi)(chi)(chi)被(bei)過(guo)充，將嚴(yan)重(zhong)影響電(dian)(dian)(dian)池(chi)(chi)(chi)的壽(shou)命。

   2. 要(yao)了解所用(yong)鋰電(dian)池(chi)充(chong)電(dian)器(qi)(qi)充(chong)滿(man)點亮時電(dian)池(chi)是否真的已充(chong)滿(man)。有(you)些(xie)充(chong)電(dian)器(qi)(qi)見(jian)到(dao)充(chong)滿(man)指示(shi)燈(deng)亮即可(ke)將鋰電(dian)池(chi)取(qu)下(xia)，有(you)些(xie)充(chong)電(dian)器(qi)(qi)要(yao)見(jian)到(dao)指示(shi)燈(deng)全亮才可(ke)將電(dian)池(chi)取(qu)下(xia)。
