3、Cr2032電池電流大概(gai)多少

Cr2032電(dian)(dian)(dian)(dian)池的最大脈沖放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流為12mA，連續放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流小(xiao)(xiao)于等(deng)于4mA。這類小(xiao)(xiao)型的紐扣電(dian)(dian)(dian)(dian)池，一般用(yong)在(zai)耗電(dian)(dian)(dian)(dian)比較小(xiao)(xiao)的電(dian)(dian)(dian)(dian)子設備(bei)上(shang)，如：電(dian)(dian)(dian)(dian)腦主(zhu)板CMOS電(dian)(dian)(dian)(dian)池上(shang)、其(qi)他記(ji)憶功能或斷電(dian)(dian)(dian)(dian)保護(hu)模塊、電(dian)(dian)(dian)(dian)子秤，計算器，電(dian)(dian)(dian)(dian)子辭典(dian)等(deng)產品上(shang)。

4、cr2032電(dian)池(chi)優勢特點(dian)：

鋰錳電(dian)(dian)池(chi)(chi)中(zhong)的(de)電(dian)(dian)解液是Pc-DME+LiClo4溶劑(ji)Pc，DME為有(you)機(ji)物，其(qi)離子電(dian)(dian)導率(lv)比(bi)堿性電(dian)(dian)池(chi)(chi)電(dian)(dian)解液電(dian)(dian)導率(lv)低2個(ge)數量級。故該電(dian)(dian)池(chi)(chi)有(you)如下特點：
貯存壽(shou)命長（不(bu)含(han)“水”，自放電小）
高(gao)容量低功(gong)率
無污染等特點。
