在(zai)连接铅(qian)酸(suan)电(dian)(dian)(dian)池之前，根据电(dian)(dian)(dian)池串(chuan)联的(de)(de)(de)数(shu)量计算充(chong)(chong)电(dian)(dian)(dian)电(dian)(dian)(dian)压(ya)，并设(she)定(ding)电(dian)(dian)(dian)压(ya)电(dian)(dian)(dian)流(liu)的(de)(de)(de)限制条(tiao)件。将12V的(de)(de)(de)铅(qian)酸(suan)电(dian)(dian)(dian)池充(chong)(chong)电(dian)(dian)(dian)到(dao)2.4V，达到(dao)电(dian)(dian)(dian)压(ya)限制状态，然后将电(dian)(dian)(dian)压(ya)设(she)定(ding)在(zai)14.4V。

根据电(dian)池大小选择充电(dian)电(dian)流。对于铅酸电(dian)池来说，其额定容量一般在10%-30%。一节10Ah的(de)(de)电(dian)池，30%的(de)(de)电(dian)量大约是3A，这个比例可以(yi)更低。80A启动电(dian)池可以(yi)在8A充电(dian)。

铅(qian)酸(suan)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在(zai)(zai)(zai)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)过程中要时(shi)刻注意电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的温(wen)度(du)、电(dian)(dian)(dian)(dian)(dian)(dian)压、电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，要在(zai)(zai)(zai)通风环境下充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)。当电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)满(man)电(dian)(dian)(dian)(dian)(dian)(dian)，且电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)降低到(dao)额定电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的3%时(shi)，即电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)完成，可断开充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)。如果电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)触底无法降低，在(zai)(zai)(zai)16-24小(xiao)时(shi)后(hou)断开充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)。高(gao)(gao)自(zi)放电(dian)(dian)(dian)(dian)(dian)(dian)会防止电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)达(da)(da)到(dao)低饱和(he)状态。也可以(yi)(yi)(yi)将(jiang)铅(qian)酸(suan)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)压设置为(wei)(wei)比(bi)推荐充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)压高(gao)(gao)10%，使(shi)铅(qian)酸(suan)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)达(da)(da)到(dao)均衡(heng)状态。电(dian)(dian)(dian)(dian)(dian)(dian)源也可反向硫化。将(jiang)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)压设置在(zai)(zai)(zai)建议水平(ping)以(yi)(yi)(yi)上，将(jiang)电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)限值(zhi)设置为(wei)(wei)低实用(yong)值(zhi)，并观察(cha)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)电(dian)(dian)(dian)(dian)(dian)(dian)压。完全硫酸(suan)化的铅(qian)酸(suan)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)初可以(yi)(yi)(yi)吸收非常小(xiao)的电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，随(sui)着(zhe)硫酸(suan)层的溶解，电(dian)(dian)(dian)(dian)(dian)(dian)流(liu)会逐渐增加。提高(gao)(gao)温(wen)度(du)并将(jiang)电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)放置在(zai)(zai)(zai)超声(sheng)波(bo)振动器上也可能有助于这(zhei)一过程。如果电(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在(zai)(zai)(zai)24小(xiao)时(shi)后(hou)不充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)，就(jiu)不太可能恢复(fu)。
