充電器由外殼、輸入線、輸出線、線路板、散熱片、各種電子元器件(電容、電阻、單片機、光藕、MOS管、二級管、三級管、開關管)幾部分組成，充電器的充電時間如何計算?電池容量看電池外面的標注，充電電流看充電器上標注的輸入電流。

　　1、充電電流小于(yu)等于(yu)電池容(rong)量(liang)的5%時：

　　充(chong)電(dian)(dian)(dian)時間(小時)=電(dian)(dian)(dian)池(chi)容量(liang)(mAH)×1.6÷充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)(mA)

　　2、充(chong)電電流(liu)大于(yu)(yu)電池容量的5%，小于(yu)(yu)等(deng)于(yu)(yu)10%時：

　　充(chong)電(dian)時(shi)間(小時(shi))=電(dian)池(chi)容量(mAH)×1.5÷充(chong)電(dian)電(dian)流(mA)

　　3、充電電流大于電池容量的(de)10%，小(xiao)于等(deng)于15%時：

　　充電時間(小時)=電池容(rong)量(mAH)×1.3÷充電電流(mA

　　4、充電(dian)電(dian)流大(da)于電(dian)池容(rong)量的15%，小(xiao)于等于20%時：

　　充(chong)電(dian)時(shi)間(小(xiao)時(shi))=電(dian)池容量(mAH)×1.2÷充(chong)電(dian)電(dian)流(mA)

　　5、充(chong)電(dian)電(dian)流大于電(dian)池容量的20%時：

　　充(chong)電(dian)時(shi)間(小時(shi))=電(dian)池容量(mAH)×1.1÷充(chong)電(dian)電(dian)流(mA)
