注意電源及電池的正負極，嚴格按指示操作：電池正極(ji)接電源正極(ji)，電池負(fu)(fu)極(ji)接電源負(fu)(fu)極(ji)。

　　初(chu)充電(dian)(dian)爭兩個階(jie)段進行：首先用初(chu)充電(dian)(dian)電(dian)(dian)流(liu)充到電(dian)(dian)解(jie)液放出(chu)氣泡(pao)，單格電(dian)(dian)壓升到2.3~2.4V為止。然后將電(dian)(dian)流(liu)降為1/2初(chu)充電(dian)(dian)電(dian)(dian)流(liu)，繼續充到電(dian)(dian)解(jie)液放出(chu)劇(ju)烈的氣泡(pao)，比征(zheng)和電(dian)(dian)壓連續3h穩定不(bu)變為止。全部充電(dian)(dian)時間約為45~65h。

　　充電(dian)過(guo)程(cheng)中應常測量電(dian)解(jie)液溫(wen)度用電(dian)流減(jian)半、停止(zhi)充電(dian)或冷卻的方法(fa)，將溫(wen)度控(kong)制在(zai)35~40℃，初(chu)充電(dian)完畢(bi)時，若電(dian)解(jie)液比(bi)重(zhong)不合(he)規(gui)定，應用蒸餾水或比(bi)重(zhong)為(wei)1.4的電(dian)解(jie)液進(jin)行(xing)調整。調整后再充電(dian)2h，直至比(bi)重(zhong)符(fu)合(he)規(gui)定時為(wei)止(zhi)。

　　新鉛酸蓄電(dian)(dian)池第一次充(chong)電(dian)(dian)后往往達不(bu)到(dao)容量，應進行(xing)放(fang)(fang)電(dian)(dian)循環(huan)。用20hh時放(fang)(fang)電(dian)(dian)率放(fang)(fang)電(dian)(dian)（即用額定容量1/20的電(dian)(dian)流放(fang)(fang)電(dian)(dian)至單格(ge)電(dian)(dian)壓降到(dao)1.75V為止），然后再(zai)補(bu)充(chong)充(chong)電(dian)(dian)電(dian)(dian)流充(chong)足，經過一次充(chong)、放(fang)(fang)電(dian)(dian)循環(huan)若容量仍低于額定容量的90%時，應再(zai)進行(xing)一次充(chong)、放(fang)(fang)電(dian)(dian)循環(huan)。
