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(chi)負(fu)極(ji)接電源負(fu)極(ji)。

　　初(chu)充(chong)電(dian)(dian)爭(zheng)兩(liang)個階段進行：首先(xian)用初(chu)充(chong)電(dian)(dian)電(dian)(dian)流充(chong)到電(dian)(dian)解液放出氣泡，單格(ge)電(dian)(dian)壓升到2.3~2.4V為止。然(ran)后將電(dian)(dian)流降為1/2初(chu)充(chong)電(dian)(dian)電(dian)(dian)流，繼續充(chong)到電(dian)(dian)解液放出劇烈的氣泡，比(bi)征和電(dian)(dian)壓連續3h穩定不變為止。全部充(chong)電(dian)(dian)時間約為45~65h。

　　充電(dian)過程(cheng)中(zhong)應(ying)(ying)常測量電(dian)解液溫度用(yong)電(dian)流減半(ban)、停(ting)止充電(dian)或冷(leng)卻的(de)方法，將溫度控制在35~40℃，初充電(dian)完畢時(shi)，若電(dian)解液比(bi)重不合規定，應(ying)(ying)用(yong)蒸餾水或比(bi)重為(wei)1.4的(de)電(dian)解液進(jin)行調整(zheng)。調整(zheng)后再充電(dian)2h，直至比(bi)重符(fu)合規定時(shi)為(wei)止。

　　新鉛酸(suan)蓄電(dian)(dian)(dian)池第一次(ci)充(chong)(chong)電(dian)(dian)(dian)后(hou)往(wang)往(wang)達不(bu)到容量(liang)，應(ying)進行(xing)放(fang)電(dian)(dian)(dian)循環。用20hh時(shi)放(fang)電(dian)(dian)(dian)率放(fang)電(dian)(dian)(dian)（即用額定(ding)容量(liang)1/20的電(dian)(dian)(dian)流(liu)放(fang)電(dian)(dian)(dian)至單格電(dian)(dian)(dian)壓降到1.75V為止），然后(hou)再補充(chong)(chong)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)充(chong)(chong)足，經過一次(ci)充(chong)(chong)、放(fang)電(dian)(dian)(dian)循環若容量(liang)仍低于額定(ding)容量(liang)的90%時(shi)，應(ying)再進行(xing)一次(ci)充(chong)(chong)、放(fang)電(dian)(dian)(dian)循環。
